Hello
Why(NES Games) it works in low frequency on the main console 6502 on 3 MHz
But Why should the frequency be high for the simulator? by Atmega and ESP32 ?
thanks

I CAN'T PAIR THE LOGITECH K360 AND LOGITECH CORDLESS DESKTOP EX110 KEYBOARD. ANY IDEA ?

Hello after trying to change out the games on the ESP32 I appear to have managed to have a ghost games list.

Rebooting...

It was possible to broadcast the video signal to a TV from ESP8266. My question is would it be possible instead of producing composite video signal to broadcast the video to a TV nearby?

I'd be interested to know if this would run on an esp32-s2.

If any of the project contributors are interested in trying, I'd be happy to pay for a couple of esp32-s2 boards for you to use.

I know it's not much money to spend but it's not really fair to ask without volunteering the hardware too.

If any of the project contributors are interested, let me know and we'll work out how I can pay for the purchase.

The esp32-s2 has pros and cons for this versus the esp32.

PROS:

• the s2 is able to map up to 10MB of PSRAM into DMA addressable memory, which is much better than the esp32 can do, and could enable large frame buffers, although I believe this library does not use a frame buffer?
• the s2 has USB which would be good for keyboards/mice/controllers
• the s2 costs less than the esp32 - not a big deal of course if you're only buying one device.

CONS:

• the s2 does not have bluetooth, so controllers/keyboards would need to be USB connected.
• the s2 only has a single i2s peripheral, but I believe this library only uses one i2s anyway - is that correct?
• the S2 only has 320K SRAM but maybe this is not an issue given the large amount of PSRAM that can be mapped in?
• the S2 only has a single core - I don't know if there's enough computing power to run all this with only one core? Having said that, it is a later version of the Extensa core used in the esp32 AND also there is a RISCV ULP processor on the S2 but I don't think that is yet supported in the ESP-IDF.

the HID server is the problem?
The program works when i comment this line

hid_update();

If I try the emulator with the line uncommented it shows this error on the serial port:

Hello,

I am trying to write an ESP32 program that outputs composite video. I tried using bitlumi's work as a starting point, but the colors are highly unstable, at least on my display. Reading through your write up, I can tell your code is superior in this regard, but I am having a bit of difficulty looking at video_out.h and understanding how it works. It looks like blit and burst are the workhorse of the operation, but they seem to be tied directly to the emulator in use and seem to do some degree of scaling and jiggery pokery depending on the particular emulator.

Ideally, I would like to be able to simplify this so it simply takes a framebuffer of RGB values and paints it. The particular resolution does not matter, but it would be nice if it were either as much as the ESP32 can handle or some fraction of that. Has anyone already done this work of adapting this code into a general purpose graphics library?

Unless you have any other suggestions, I probably will start by finding out what is the highest resolution emulator and try working backwards until I have a way of setting individual pixels.

I get working this type of controller, is very cheap and easy to find in ebay or other online sites:

https://i.ytimg.com/vi/N2BsJA6EAOo/maxresdefault.jpg](url)

To make it work you need to press (with the controller OFF) the B button and then press the Home button (while keeping the B button pressed). This make the controller act as a keyboard. When you press any button this will cause a short keypress. When you release the key it cause anther short keypress but from other key. This force me to modify the code in this way:

I dont know how to add this functionality but i share my implementation:

gui.cpp:

bool key(int keycode, int pressed, int mods)
    {
        printf("key:%02X %02X %02X\n",keycode,pressed,mods);
        if (pressed && _visible)
            _click = 1;

        if (pressed && keycode == 12) { // F1 - GUI key
            _visible = !_visible;       // toggle GUi
            if (_visible)
                _overlay->frame();      // draw the frame when it first appears
            _click = 1;
            return true;
        }
        if (!_visible)
            return false;

        if (pressed) {
            switch (keycode) {
                case 30:        // 1 key
                case 31:        // 2 key
                case 14:        // 0 key
                    disk_key(keycode-30);
                    break;
                case 15:
                    enter(mods);    // return
                    break;
                case 26:    // up
                    move_v(-1);
                    break;
                case 7:    // down
                    move_v(1);
                    break;
                case 27:    // left
                    move_tab(-1);
                    break;
                case 4:    // right
                    move_tab(1);
                    break;
                case 11:   // left control key
                    break;  // FIRE
            }
        }
        return true;
    }

emu_nofrendo.cpp

 virtual void key(int keycode, int pressed, int mods)
    {
        switch (keycode) {
            case 26: pad(1,event_joypad1_up); break;

            case 24: pad(1,event_joypad1_b); break; // option key event_joypad1_b
            case 9: pad(0,event_joypad1_b); break; // option key event_joypad1_b

            //case 59: system(pressed,INPUT_PAUSE); break; // F2
            //case 61: system(pressed,INPUT_START); break; // F4
            //case 62: system(pressed,((KEY_MOD_LSHIFT|KEY_MOD_RSHIFT) & mods) ? INPUT_HARD_RESET : INPUT_SOFT_RESET); break; // F5
        }
    }

how we can add this functionality?

Is there a way to save the state of games? I saw that nofrendo has something about save states don't know if that's related to it though. If it isn't possible right now it should definitely be added that would make this awesome project perfect.

Can I use NES Controller? How to set it up? Is there a code for the relevant input device? Thanks！

Any suggestions as to what I might be doing wrong?

Rossumur,

Which ESP32 Arduino Core release version did you use to build and run this project?

Thanks.

I'm thinking of writing a Bootloader for all the emulators.
So... this is what i'm thinking:

*The emulators are in the app0 partition
*The roms are stored using the CrapFS in the app1 partition
*The first time the emulator is launched it copy the roms in the spiffs to the app1 partition....

With the CornN64 fork that uses an SD card to store the roms we can have the spiffs partition free and...

*Use the partition app0 to store the bootloader.
*The bootloader is a menu that read a folder called "emulators", display the binary files and the user select what emulator is going to run
*When an emulator is selected from the SD card, the bootloader copy the binary to the app1 and mark the partition as boot source. Then the bootloader restart the ESP booting the app1 (the emulator) partition.
*When the app1 (the emulator) start, mark the app0 as the boot source. After that it start the emulator.
*The partition for ROMS (CRAPFS) is the FFAT or SPIFFS where the roms are copied from the SD.

Can this work?
Im planning to use this library for writing the Menu:
https://github.com/Roger-random/ESP_8_BIT_composite

And this is the code that i use to switch between the apps partitions:

#include "esp_partition.h"
#include "esp_image_format.h"
#include "esp_flash_partitions.h"
#include "esp_ota_ops.h"

esp_err_t err;

void setup() {
  const esp_partition_t *partition_running = esp_ota_get_running_partition();
  const esp_partition_t *partition_boot = esp_ota_get_boot_partition();
  const esp_partition_t *partition_ota0 = esp_partition_find_first(ESP_PARTITION_TYPE_APP, ESP_PARTITION_SUBTYPE_APP_OTA_0, NULL);
  const esp_partition_t *partition_ota1 = esp_partition_find_first(ESP_PARTITION_TYPE_APP, ESP_PARTITION_SUBTYPE_APP_OTA_1, NULL);

  switch (partition_boot->address) {
    case 0x00010000:
      ESP_LOGI(LOG_TAG_MAIN, "Boot partition: ota_0");
      break;
    case 0x00150000:
      ESP_LOGI(LOG_TAG_MAIN, "Boot partition: ota_1");
      break;

    default:
      ESP_LOGE(LOG_TAG_MAIN, "Boot partition: unknown");
      break;
  }


  switch (partition_running->address) {
    case 0x00010000:
      ESP_LOGI(LOG_TAG_MAIN, "Running partition: ota_0");
      err = esp_ota_set_boot_partition(partition_ota1);
      if (err != ESP_OK) {
        ESP_LOGE(TAG, "esp_ota_set_boot_partition failed (%s)!", esp_err_to_name(err));
      }
      else{
        ESP_LOGI(LOG_TAG_MAIN, "esp_ota_set_boot_partition ota_1 OK");
        
      }
      break;
    case 0x00150000:
      ESP_LOGI(LOG_TAG_MAIN, "Running partition: ota_1");
      err = esp_ota_set_boot_partition(partition_ota0);
      if (err != ESP_OK) {
        ESP_LOGE(TAG, "esp_ota_set_boot_partition failed (%s)!", esp_err_to_name(err));
      }
      else{
        ESP_LOGI(LOG_TAG_MAIN, "esp_ota_set_boot_partition ota_0 OK");
        
      }
      break;

    default:
      ESP_LOGE(LOG_TAG_MAIN, "Running partition: unknown");
      break;
  }
  delay(5000);
  esp_restart(); 
}

void loop() {
}

Thanks a lot for such a wonderful & fun project! It works flawlessly. 🥰
I try to study the code (hoping to learn something) but was just totally overwhelmed by its complexity 😅. So proceeded to try the next best Noob move, poke around the code...

Experiment #1: Adding an UART input (Arduino as an game input to the ESP32).
As soon as I add the line Serial1.begin(115200, SERIAL_8N1, 16, 17); into Setup() & pump Data through the UART. Even before adding any code for Serial reading, the Vertical Sync on the TV screen is already messed up.
So I am wondering if Serial is somehow affecting the video output timing on Pin#25?

Taking a hint from CornN64 #16 modification, I try to mess around the Sync parameter but to no avail. 🥲

Anybody have any pointer/suggestions on where I should start digging next? 🙏🏻

Hi, I must say that this project is amazing, and it is a shame that its development was stopped. I hope that somebody could help me anyway.
I tried to run this software on an ESP32-CAM board, and after solving problems like downgrading the ESP32 board package to 1.0.4, I was able to compile it and upload it to the microcontroller. The problem is that it does not load. These are the logs:

set_pref("recent",path);
_emu->insert(_path + "/" + path,flags);//exacly this line is responsible for my headaches
}

I've tried to find out why it does not work, but my knowledge is not enough to solve the problem :(. Any help would be very appreciated :)

The error:

The Rom:

It's possible to fast forward in the rom menu list? It's a bit difficult to find a rom when the rom list is to big.

Thanks!

Is there enough CPU leftover to output to a small TFT instead of a TV?

I was hoping you could post a picture of the actual wiring. I am a beginner at interpreting wiring diagrams but was hoping to build this for my son's gradution.

Thanks!

Just wow, great project!

This isn't a real feature request because it is out of scope, but I wouldn't mind your 2c.

How would you go about overlaying this video on another e.g. making an OSD (text etc) to display over another video source? It is possible to use something like the lm1881 video sync separator, but what would be the best way to use your lib and sync to this video input?

If you've read this far here is the end goal application. FPV quad racing uses an analog video transmitter and sometimes the video receiver misses the vertical or horizontal sync pulses. This of course causes static lines or scrolling. Having a video source generated on the video receiver end that is synced with the incoming video transmission from the quad would be useful for inserting the sync pulses. This helps to eliminate momentary static in the video.

There are now a few commercial products available, but it would be awesome to have an opensource option... long term goals.

Cheers

What do you think of making your solution compatible with FabGL?

http://www.fabglib.org/classfabgl_1_1_canvas.html

I don't know if this is practical, but if so then it would be great to use the FabGL VT100 terminal and graphics library using your PAL and NTSC.

Hi,

I need some help.

I don't get video with the sketch.
In the console I see a correct boot, Wiimote pairing and .nes load from SPIFFS, but no video

Board: DOIT ESP32 DEVKIT V1
Tried both pins 26 and 25, PAL and NTSC and ATARI and NES setups
Bitlunis CompositeVideoSimple sketch works fine with same setup (ESP32 board, pin 25 and same TV)
In the Oscilloscope I see video output with Bitlunis sketch but not with esp_8_bit nor espflix

Thanks in advance!

#include "esp_int_wdt.h"
#include "esp_spiffs.h"

Is it easy to find game ROMs, how do I convert to hexadecimal to put in ESP?

After placing the ROMs in the data folder for the appropriate emulator not all of them show up in the menu.
I kept the names short, with no spaces. Sometimes if I change names device ends in a boot loop where it tries to format FS. A list of supported ROMs and appropriate names would go a long way.

I'm thinking of taking your code and seeing about making a takeabout console to friends houses and plugging into their TV's. Do the libraries support mutliple BT Controllers / Wii Motes being hooked up ?

I will take a look, but thought input from you would be a good starting point :)

This is a very awesome project, I pulls so many cool things together. I recently did something similar with just a black and white screen output to TV and a PS3 controller for an Arduboy type console
https://github.com/tonym128/ESP32_Arduboy/tree/tvout

https://github.com/badvision/esp32_nesemu

This user commented on your project on HaD and had added some features to the NES emulator, notably SD card use, purported improvements running Metroid, SRAM support and save games.

I'd be very happy to have this with composite out. I'm looking to design a little keychain NES with one of the more high spec WROOM32 modules so it has more RAM and storage.

(Thank you very much for this. It's making being immunocompromised and quarantined in not as tough)

Hello do you have any suggestions for a graphics library to use with this?

Maybe like the Adafruit GFX or are there others libraries that might be a better start for doing games such as gameduino library or something - I'm just guessing?

Even a simple mode setting/test pattern example would be fun to play with to try out the various resolutions.

Can you suggest where to get started/examples etc or is it too early?

thanks

Is there anyway to add old SNES controller support for this?

First, thanks for the project. I was wondering, its possible to add a Gameboy emulator??
There is one ( https://github.com/PocketSprite/8bkc-gnuboy ) but uses a LCD screen instead of the video out???

Hello,

I wrote a comparison of esp32 video solutions here:
https://www.reddit.com/r/esp32/comments/gpezk3/feature_comparison_of_esp32_graphics_sound_game/

I wonder would you mind confirming please, what is the maximum resolution that your solution can do for each of PAL & NTSC? Also what is the color depth?

What is the maximum resolution that you think your solution could do, presuming you are not already pushing it to the max?

As a side question, can you indicate what plans you have from here for this software?

thanks

This project appears to not be updated much. I wonder is there a project that uses the base work done here and is actively maintained?

This fork appears to be the most ahead in terms of commits - presumably it is implementing fixes and enhancements.
https://github.com/CornN64/esp_8_bit/commits/master

Maybe the project owner could update the status or direct people to a more maintained version?

Can you release also a binary image to flash with Flash Download Tool?

I am questioning why I see only 3 FILE_0x.DAT files when there appear to be 5 deleted files from the Directory. Could there be a bug where every other FILE_0x.DAT file is not displayed?

I am using my APE to USB to make .ATR files/images of many real/physical diskettes using both a Happy 1050 and an indusGT drives. Later I look at some of the resulting .ATR files within the ATR Image Explorer (a great tool). On some images I see one or more .DAT files that always have names of the form: FILE_0x.DAT as in the 2nd picture. What are these? My guess is these were files that were 'deleted' therefore they are not found in the Directory (3rd picture) but their data sectors are still found/read by ProSystem. Is this the case? Note: ProSystem did not report any errors when it read this particular disk image '01a.ATR'

What are the 3 .DAT files circled in red?

Note 5 of the file names in the Directory are not listed above. Where these 5 files deleted? Maybe ATR Image Explorer has a bug in that it is not displaying FILE_02 or FILE_04?

It would be a boon to the usability if a controller could be paired to the device persistently.

Hello Rossum,

I really enjoyed this project and I'm impressed by your knowledge and results!

I have deployed the ESP_8_bit to my ESP32 WROOM. It runs each emulator with no issues.
But when I tried to attach a Bluetooth 3.0 keyboard I observed that a few seconds after it starts to display images to the TV, ESP32 reboots.

So I decided to turn on HCI Messages and to log the serial output to help on finding out
that is going on. The messages I got are at the end of this message.

It clearly recognizes the keyboard as can be seen in HCI messages:
20:73:00:3C:DF:41:402500 input device added
20:73:00:3C:DF:41 connected on handle 129

Last messages before crashing and rebooting are:
HCI_MAX_SLOTS_CHANGED_EVT 3 bytes
unhandled hci case

An unhandled hci case is causing an exception fault.
HCI code doesn't handle HCI_MAX_SLOTS_CHANGED_EVT and crashes followed by an ESP32 reboot.

Best,
Rodrigo Corbera.

Please make it usable on this board (TTGO VGA32 1.4): http://www.lilygo.cn/prod_view.aspx?TypeId=50033&Id=1083&FId=t3:50033:3

I'm trying to make the sketch work in a ESP32 mini, and since I do not have any composite video-capable devices at home, I'm trying a 3xRCA to AV cable. After a few seconds connected, I can see some noisy vertical lines and some noisy colors from time to time, but no sound. Not sure if it's a connection problem of if there is something I'm missing. Maybe I didn't understand the scheme.

What I've done:

• Solder positive of video cable to pin 25
• Solder negative of video cable to ground
• Solder both audio left and right positives to pin 26 through a 1k resistor (and set pin 26 as audio out in video_out.h)
• Solder both audio left and right negatives to ground through a 10nf capacitor

My bt keyboard connect after video_init.

Rebooting...

I'm having a weird sync problem with one particular screen. It's a dismantled screen from a cheap car rear camera monitor with composite input. The display is not great, but it works fine with other devices (Raspberry Pi, game consoles etc) however with esp_8_bit (or espflix for that matter) the image is crisp but it slowly scrolls vertical (same result with both PAL and NTSC). The output is crisp and steady on other displays so I'm thinking it must be something with this specific combination - and most likely the sync signal passed from the esp32 to the display or maybe the resolution. Sync signals and timing have never been my strong suit, so I haven't been able to find where in the source code the resolution and/or sync can be adjusted. Can anyone point me in the right direction?

I got a snippet from here:
nkolban/esp32-snippets#230 (comment)

And although my phone detects it as a keyboard, I can't get it to connect with the esp-8bit.

My plan is to put the esp32 in an old nes controller.

Btw this project is awesome. All the beers for you if you ever come around Argentina once we're done with covid.

Is there any chance to replace bt-stack with https://github.com/bluekitchen/btstack ???
https://gitlab.com/ricardoquesada/unijoysticle2/blob/master/docs/supported_gamepads.md

please rewrite video_out.h for esp-idf framework.

I think that when the execution start the best option is to show the menu. Sometimes when the emulator fails to load a rom to the app0 partition fails to boot and the user needs to reprogram that partition using the arduino IDE. so... if the menu have an option to format that partition, and the emulator menu shows at start (No loading the rom) is a good option to fix this issue.

BTW i think that if the audio pin is mapped to the IO17 and make free the IO18, we can use the standart pins for SPI protocol making it easy to atach a SD card to that pins.
Im trying to understand the CRAPFS part of the code to load roms from the SD card.

Amazing project! Given that you're already doing Z80 emulation are you thinking of adding emulation for any of the early 80's arcade machines? (Donkey Kong, Pac Man, Galaga, Galaxians, Rally X, Route 16, Crash, Head On, Asteroids, etc.)

Hi,

I compiled esp_8_bit with success and uploaded it to NodeMCU 32 module. I found pin with video signal, connected it to TV and no image appeared. Then I checked it on the oscilloscope and I see that time between each line is very short... 2uS.. as I remember, time to draw one line shall be about 64uS... I have no idea how to set proper value and where?

hello, i need help with this error.
