I'll try to force it to run on a different line. thank you!

It would be easy to track it while it's running, but it's blocked because the execution is stopped.

hello I only patched games that can run on mame using a debugger, I would like to get some hints on how to bypass patch for a game that won't boot. The game I want to patch is 'Spikeout'. To find the part in the main CPU's code that accesses the location (fe1a0000~fe1a001f) of the 315-5881...

I successfully wired the power and turned it on, but an 'E1' or '13' error occurred. I think it's probably a gpu board(maybe BGA cold soldering) issue. Does anyone know about this?

wow! thank you so much! I'll try wiring it.

thank you! I will try to make it well while looking at the wiring diagram. I need to boot after replacing the rtc and hdd. I hope the bga isn't broken.

I got a Cobra board. I need to make a power supply, but I'm curious what the 3.3 volt connector is divided into purple and blue wires. Are both purple and blue 3.3v or some other voltage?

The code that writes a hexadecimal number to keycus and retrieves the value converted to decimal is approximately 10 lines of code. It is impossible to convert hexadecimal to decimal within the CPU by modifying about 10 lines of code. And I am not familiar with mips programming, so programming...

I will also have to look into the keycus function of quiz angel 3 / point blank 2. It's hard to imagine that among all Namco's keycuses, dancing eyes' keycus is the only one that functions as a hexadecimal converter.

Since I don't have a star sweep board, I looked into what star sweep's keycus does in mame debugger, but it wasn't used as a hexadecimal converter.

I have been thinking about making a BGA socket because of frequent failures of BGA chips on model 3 step2.0 graphics boards. This may be fixed by socketing the Cobra board's BGA chips. https://www.advanced.com/products/bga-socketing-systems/socket-adapter-systems

This is a modified patch that allows the x and y axes to be read as 5v analog values like in the type2 gun io exclusive game. You need a type 2 gun io or a device that converts the x and y axes into a 5v potential difference using Arduino. It works if you connect the analog values of the...

hello. I wanted to convert the Namco system11 games to Dancing Eyes, so I applied a patch to bypass keycus in mame and succeeded in booting and running the game. However, keycus is used to convert hexadecimal to decimal, which displays the remaining time during gameplay, so when I run patched...
