Freezing Issues / Muffled Amplified Sound about summercart64 HOT 23 CLOSED

Sorry but this sounds like a faulty hardware and no firmware update would help here. Can you post photos of the PCB with marking on the chips visible? While I might believe your cart uses required parts, there's still a possibility a different part was used that is not compatible.
Also please run built-in tests by holding button on the back of the SC64 while switching power on the console. Let tests run in a loop for some time and report results here.

@Polprzewodnikowy This is one of my carts, the BOM is the "fixed" PCBWay one.

I ran the test twice and both times I got a "Mismatch" and it stops from there..

Right, there's definitely something wrong with the connection between SC64 and your console. Before drawing any conclusions you can try:

• Clean your cartridge slot in the console with an alcohol
• Run the game with USB cable connected to a power source, doesn't matter if it's not recognized by the computer
• Replace your power supply

I hope you've tested your console with a retail game beforehand and it works without any hiccups. Keep in mind that custom cartridges draw more power and your power supply might just barely provide enough power to run retail game, while SC64 might get underpowered.

My nintendo 64 works fine with other carts. I have an ED64 and an Everdrive X7 and never had issues. I have retail games and never had issues. My power bricks are fine as I have 2 of them. The console was of course cleaned since I put on a new shell.

I will test this with my spare Nintendo 64 I have. I will post results.

It could also be N64 slot pins being slightly widened with regards to the PCB depth of the SC64 PCB, especially if the PCB was ordered in the wrong depth (1.2mm).

I purchased this from Phenom Mod.

The pcb thickness is whatever the PCBWay share project is

I have tested this with 2 N64's. 2 different power supplies and one attached with the actual DD. All 2 mismatch errors. This is the only Nintendo 64-related item in my possession that gives me issues. I think the cart is faulty. Getting another one would prove if I was right or wrong.

Yeah that definitely seems like a faulty unit. Thank you for the photos, I can see that bits 8, 9, 10 and 11 are wrong. I suspect faulty SDRAM chip but confirming that would require testing the memory via USB interface and I have not developed such test yet.

So then I would have to open an RMA at Phenom Mods? That is where I got the Summercart from.

Yes. Email me your order number and I'll send you a replacement and a return label

@Kinooshi823 Suggest you close this issue. Just to keep the repo issues clear.

from summercart64.

I got the cart back. Some bad news is that the hardware is fine. As I said, I test the carts before shipping.

from summercart64.

@Kinooshi823 are your consoles modified in any way? Like HDMI mod or an overclock?

Both consoles are stock unmodded. Both have expansion paks.

I didn't even know you could overclock a 64

I see you're deleting comments. Please understand that we are trying to get to the bottom of the problem, asking questions is a part of the troubleshooting. I'm still looking through the firmware code to locate any cause for this problem.

Would be great if you can update firmware and do some testing for me but preparing new firmware with more tests will take couple of days at least.

The comment I deleted was more of me upset of the situation and wasn't information relevant to the troubleshooting here.

I cannot update the firmware as I don't have it in my possession and it was sent back. I am currently thinking if I want a replacement.

Also, firmware updating doesn't seem to be easy right? as I am not adept with CMD.
