mesen-x's Introduction

Mesen-X

Mesen-X is a fork of Mesen, which is a cross-platform NES/Famicom emulator for Windows & Linux built in C++ and C#. The original Mesen project has paused development, and this fork is meant to collect patches contributed by the community.

Changes include:

Support for newer versions of Mono, for running Mesen on Linux
ESPM homebrew expansion audio support
HD Pack improvements
Replaced VRC7 synth code with Nuked-OPLL
Debugger improvements, for Alchemy65

You should probably use Mesen2 instead if you are able to.

Development Builds

Development builds of the latest commit are available from GitHub actions. For stable release builds, see the Releases section below.

Warning: These are development builds and may be unstable. Using them may also increase the chances of your settings being corrupted, or having issues when upgrading to the next official release. Additionally, these builds are currently not optimized via PGO and will typically run 20-30% slower than the official release builds.

Follow either of these, select the top-most entry in the list, and then click the link under "Artifacts" near the bottom.

Releases

Windows

The latest versions can be found on the releases tab

Ubuntu

There's a separate Linux release available on each release in the releases tab. You should be able to use that in most cases if you are using Ubuntu.

The Linux version is a standard .NET executable file and requires Mono to run - you may need to configure your environment to allow it to automatically run .exe files through Mono, or manually run Mesen by using mono (e.g: "mono Mesen.exe").

The following packages need to be installed to run Mesen:

mono-complete
libsdl2-2.0
gnome-themes-standard

Note: Mono 5.18 or higher is recommended, some older versions of Mono (e.g 4.2.2) have some stability and performance issues which can cause crashes and slow down the UI. The default Mono version in Ubuntu 18.04 is 4.6.2 (which also causes some layout issues in Mesen). To install the latest version of Mono, follow the instructions here: https://www.mono-project.com/download/stable/#download-lin

Roadmap

Things that may or may not be added in the future, in no particular order:

Support for more UNIF boards and more NES/Famicom input devices
Shaders
TAS editor
Support for new homebrew mappers
More Lua features

mesen-x's Issues

Ability to rewind out of a CPU crash

I heard it suggested that CPU crashes "trash the rewind buffer" - need to investigate this and see if I can fix it?

[Enhancement] Does it possible to make option for sound...

Just look that great video, explaining on how sound can be enhanced highly
https://www.youtube.com/watch?v=8RrQrATnXXY&t=68s&ab_channel=KYLXBN

Ability to set custom display refresh rate depending of Region (like mkwong98 fork)

Original Mesen have a nice option to force user-specified refresh rate in fullscreen mode.
User can select it from drop-down list of refresh rates that your GPU/Dispaly support:

Nestopia had "auto" refresh rate function in fullscreen depending of region.
For NTSC emulator try to set 60 or 120 Hz, prefer higher value, if hardware supported it.
For PAL/Dendy emulator try to set 50 or 100 Hz, prefer higher value, if hardware supported it.
It was really nice when i had CRT, which supported 60-75-85-100-120Hz

I guess nice idea is combine this methods.
To make an separate "fullscreen preferred refresh rate" option.
Two drop-down menus where user can set prefferred hardware refresh rate:
one for NTSC, second for PAL (for PAL/Dendy if system=NES)

This feature was added to Mesen fork by mkwong98:
mkwong98@708a13b

It works very well.

True reason of this topic/request - ability to smooth (no-tearing) scroll, which is avaliable ONLY
when physical refresh rate corresponding with emulator output.

When emulating NTSC 60Hz mode - preferred physical refresh rate = 60Hz or multiple value (e.g. 120Hz)
When emulating PAL/Dendy 50Hz mode - preferred physical refresh rate = 50Hz or multiple value (e.g. 100Hz)
This settings + vsync gives true smooth scrolling.

Most of PC-hardware runs at default 60Hz refresh rate, so it's good for NTSC but cause jerky scroll on PAL.
Not so much emulators have ability to switch between refresh rates separately depending of region.
Of course, i mean fullscreen mode.

P.S:
Feature similar Nestopia was added to puNES/QT (linux and winD3D/OpenGL) in lastest commits.
It have "Adapt Refresh Rate to the Region" checkbox:
For NTSC emulator try to set 60 or 120 Hz, prefer lower value, if hardware supported it.
For PAL/Dendy emulator try to set 50 or 100 Hz, prefer lower value, if hardware supported it.

Cannot import labels from old version cc65 dbg file

For some reason, I have to use cc65 version v2.13.3.
As the title, I found that there is a huge difference between v2.19 dbg file and v2.13.3.
Is there any possibility of importing v2.13.3 dbg file to mesen or other ways that can use mesen-x source-code level debugging
Thanks!

(This shows after import starter.dbg)

test.dbg build from v2.19
starter.dbg build from v2.13

[Enhancement] Add ability to turn on and off NTSC Overscan Borders.

I think the title of the issue is self explanatory.

Read/Write CPU registers with Lua scripts

Add functions to read and write CPU registers using Lua scripts

[Request] The ability to add the new header database (or merge the updated one)

Can you add an option to add the updated NewRisingSun database?

It looks like this:

I still see my task bar.

macOS port possible?

Hey Guys!

So Most emulators, like iNES and higan have macOS versions. (and FreeBSD Versions)

I'm wondering if a macOS port is possible.

Is it possible? 🤔

Mesen crashes during Netplay on Host with Error 0x80004005

hi,

i did some more netplay testing and i noticed that sometimes the host will crash with a runtime error. here is a screenshot with the error message. the crashes happen randomly and they're not very often but they do happen once or twice per play session.
it's also worth mentioning that when the host gets the error the client app goes into not responding until the host clicks ok, then the client disconnects and the game runs in offline mode.

i made a post on nesdev a while back with some of the troubleshooting i did, you can find it here. someone suggested this might be an engine code issue and not .net but i couldn't replicate the crash consistently.

both the host and the client are using the latest build from commit 86326e8 on windows 10 and the game played is battletoads (usa).
i haven't tested any of the other builds from the other forks but i'm assuming it's still there since no changes to the netplay modules were made.

thank you

[Feature Request] Have an option to choose a folder for ips and bps patch storage

Suggested to me by CVReynolds over ROMhacking.net

AVI desync issue when rewind is used

From the original Mesen's issue list:

"Hello. So it seems as though the more that rewind is used while recording to AVI the more that the sound becomes out of sync with the video. Looking at the file information from Virtualdub confirms this with the sound length trailing behind the video length. Additional testing shows that it's not the duration of the rewind, but how many times it's done."

VRC5 Mapper support

VRC5 is a mapper used in Konami's "Space School" series of games. Emulator "FCEUX" already has support for this mapper. Not sure if this mapper already exists in Mesen, but if not, please add this mapper.

I can't save settings

When I try to save any settings,then it jsut doesn't work,when I display the settings again,then I see that nothing got saved.

Crash when loading previous 'auto saved' state

I'm not sure what it's called, but when you open up Mesen without loading a ROM you are presented with a grid screenshots of the last games played. When you click on one it is supposed to load that ROM.

In Mesen-X it crashes shortly after clicking any game. I've tried a few different games, all with the same issue.

Here's a video. Note that the video ends at the moment Mesen crashes.

Error message box instead of the about screen

With the latest 2022-05-15 Snapshot on GNU/Linux when I go to the menu Help -> About, a large error message box appears. This does not happen with the last official release.

Emulator Mesen(NES) setup problem "SteamDeck"

Hello people... I'm angry and I don't know why it's not working for me..... I wanted to set for example up, down, left... It keeps flashing and I can't set... Interesting that it works Duckstation, SNES, Nintendo switch, etc.... I only have one problem because of the NES.. Don't know why? Thank you and I will show the video..

I think the problem will probably be the program or the driver? Have you also tried or not?

Taskbar not being hidden in fullscreen mode

Hello,
I run Mesen onto my Cinnamon desktop environment. By switching to fullscreen mode, the Cinnamon taskbar is always visible, unless I configure auto hide in the Cinnamon panel settings, which I don't want as I need it to be fixed. Never tried with different desktop environments, but I believe the same will happen. Is there any way to have a proper fullscreen, and keep the taskbar fixed?
Thank you

Add Lua function to check if it's running as a result of TestRunner mode

Add the ability to determine if the script is running from the script window or from https://www.mesen.ca/docs/apireference.html#test-runner-mode - as far as I can tell it's doing InteropEmu.SetFlag(EmulationFlags.ConsoleMode, true); but you can't fetch that from a Lua script.

Recording a movie when paused crashes Mesen

Also, recording a movie is binded to Pause, which I can't change. It appears as blank in settings.

[Feature Request] Improve the "automatically configure controllers when loading a game" function

Extend the "automatically configure controllers when loading a game" function to use the info from the rom header if the built-in game database is disabled or the game is not in the database.

Binaries missing from AppVeyor

Artifacts older than 6 months are automatically deleted.

ROM's autoplay

Hi I installed Mesen on Windows 11 and went to play ROMs, each ROM I played it would only go into Demo view. The ROM would not run the game.

Is there a known issue?

[Libretro] Build errors on Windows with Mingw64

Hi, thank you first and foremost for continuing to work on this emulator. I am currently trying to compile a libretro core of the latest code from this repository as well as the one created by @mkwong98, using the makefile contained in the libretro folder with Mingw64 on Windows 10 x64.

Unfortunately, when attempting to build the libretro version in either repo, the compiler throws out several errors and ultimately aborts the process. A few examples of the errors I am getting:

In file included from ../Core/APU.h:7,
                 from ../Core/APU.cpp:2:

 1332 |   switch (m) {
      |          ^

To the best of my knowledge, most errors seem to be related to either the audio updates that have been implemented recently or something to do with the system model identification, but unfortunately I lack the expertise needed to resolve this issue. Any help or suggestion in this regard will be much appreciated!

For further reference, the same build process works fine by either using SourMesen's original repo, or the libretro version (which is essentially a mirror of Sour's work) found here: https://github.com/libretro/Mesen

Debugger Breakpoints not saving correctly on Linux / Mono

Info over at SourMesen#881 (comment)
I'll need to test if this is an issue for Mesen-S too

Length less than zero error when importing debug symbols

Steps to recreate:

First clone this repo: https://github.com/jeffythedragonslayer/snes-pal-ntsc-detector
In build.bat, add -debug-info after the .list but before the .asm file in the call to cl65
Then build
Open the ROM in Mesen-SX and open the debugger
Then import labels and select the .cpu.sym file

[Feature Request] RetroAchievements implementation

Well, as all knowing, The Mesen-X is as far most precisely emulator disponible currently and it would be extremely useful for RetroAchievements players who looks for precision, it's would very nice if the Mesen-X integrate achievements in your system, like other emulators doing as exemple the Duckstation.

[Feature Request] Different deadzones for x and y axes.

Hi there. Just wanted to suggest adding different deadzones for x and y axes on gamepads, it would be helpful for some people.

[Request] Submit Mesen-X to Flathub

If Mesen-X was available on Flathub, it could be easily installed on the Steam Deck. This would allow the use of Mesen without the need to use RetroArch.

https://github.com/flathub/flathub/wiki/App-Submission

I have not verified that the code meets the requirements for app submission.

Thanks!

[Request] port to RetroArch

Is there any plans to port this to RetroArch?

Since the link to the latest build is not working right now i would like to have nighly builds for this emulator, i dont know how to compile, sorry :S

A couple of name suggestions for Mesen and Mesen-S

I don't know if this fork and the Mesen-S fork are active, but I already have some name suggestions for these forks, if y'all are interested: Mesen++ for Mesen, and the same thing for Mesen-S, which would Mesen-S++.

What do you think?

Running Mesen-X headlessly with xvfb-run

Hello there. I'm trying to run Mesen-X inside my build process, which worked before with SourMesen 0.9.9. I've run this test code locally and it works correctly, so I assume there's some new problem with running with a headless X server. Any pointers for getting it working would be helpful. Version details of the container:

[Bug] Fast Forwarding doesn't work on Version 1.01

I put my usual settings for my shortcut keys on fast forwarding and rewind, but when I started a game, the rewind feature works but the fast forwarding feature doesn't work.

Steps I did:

1: Set up shortcut keys for my Fast Forwarding (Hold Button) and Rewind (Hold Button)
2: Started up the game "Star Tropics"
3: Pressed the key for fast forwarding, nothing happens.
4: Pressed the key for rewind, and it does rewind.

Is possible to add RAM search feature?

Current Mesen has memory viewer, but it's not so convenience to find specific address, so if RAM search feature be added, it will more convenience!
Also I think current turbo setting is kindly...stupid, two slow levels are actually slow as turtle, so I think this solution would more better:
Fastest: 1 on 1 off (No change)
Fast: 2 on 2 off (No change)
Slow: 3 on 3 off (Change from original 4 on 4 off)
Slowest: 4 on 4 off (Change from original 8 on 8 off)

[Feature Request] Dark Theme

I believe that if there was an option for a dark theme or even a QT interface the project would look more professional and pleasing to the eye, Mesen-X is without a doubt the most accurate NES emulation project currently, but it needs improvement your interface to be more organized and efficient.

Hello Issue / TAS

Hi,
I would like to thank Sour for everything he did to bring Mesen and Mesen-S to us.
I can't imagine the amount of work he put in , and how patient he was with all the issues submitted,
I will never forget this in my life, Thank you very much Sour M.Bibaud.

Nova Thank u for forking Mesen and willing to work on it.
I would start by suggesting a tas implementation , that deals with fceux format too.
Take care :)

[Feature Request] That it uses the qt theme

I don't like the white look

I want that it uses my qt theme,it would look so much better then.

Per-channel visualizer for NSF playback

Windows build doesn't work

I followed the instructions in COMPILING.md, and I got these errors when launching the built Mesen.exe

[Feature Request] Add a script event that is called regularly, even while the emulator is "paused"

Currently scripts cannot continue running while the emulator is paused, as they have no way to resume while paused. All of the currently available events hook to things like end of frame and sprite0 hits, none of which occur while paused. I'd like an event that runs on a regular basis (~30 fps would be plenty) that would allow the script to manage LuaSocket connections even while execution is paused.

I have a partial implementation of this in a PR. This PR goes into much more detail and includes a simplified script for testing the desired effect: AlchemicRaker#1

Mesen does not display properly on a HiDPI display

This issue was already reported here and here and it was never fixed since. On GNU/Linux with a 4K display, the application does not scale correctly

.

Issue with Dualshock 4

I tried to use Dualshock 4 for Mesen, and it worked in a first try. But when I tried another one it didn't work at all. I don't know what is happening. And no is not the controller, because it worked on others emulators.

Mapper 28 (Action 53) seems to initialize wrong

Action 53's mapper should power up with $c000-$ffff mapped to the last 16KB of the ROM. However, Mesen initializes all mapper registers to zero, so as soon as UpdateState() gets called, the first 16KB is put in $c000-$ffff because of a zero outer bank.
