Raspberry pi gameboy advance emulator Patch#
That patch script can also change it so all tests are disabled, or so that you can always get the "push start to aging" prompt, and the following animation, regardless of whether you pass all tests or not. Some of them will freeze up a system though (I think), so they might be disabled for this reason. I also wrote a script to patch the same ROM to use the unused tests instead of some of the default tests. I also added a python script to patch the ROM to write the test results to address 0004 (in the BIOS, so it won't do anything, you can catch these writes and show print them to the console to see what the test returned).Īfter finishing decompiling the tests that are enabled in the AGS ROM with md5 sum `9f74b2ad1d33e08e8a570ffe4564cbc3`, I noticed that there were some tests that were unused.

In my decompilation, besides the actual code for the test, I also documented where in the ROM the test functions start, where they return, and what the return flags mean. The hardest test to decompile was the DMA address control test, since it was so large, it used weird inlined functions it seemed and GHidra kind of messed up the stack on that one.Īll tests in the suite return flags for which parts of the test the system failed, but these are never seen on the screen. The code was quite clean, and most of it wasn't too hard to decompile. You might recognize it from the following screenshot:
Therefore, I decided to decompile the tests myself, and put them in a central place to help future emulator developers! There wasn't much documentation on the tests other than what Normmatt had already decompiled, but this led me mostly to the names and entry points (this was especially useful!) of the tests. I have used it myself mostly to see how well my emulator performed in it while developing it, but I never knew exactly what the tests did.
Hello everyone, I am back with more GBA stuff.ĪGS Aging Cartridge is a test used by Nintendo to test GBA systems. Also I don't know if there is something about an emulator that would prevent my first idea, but again I'm a newbie and I would appreciate opinions and information, its hard to find. To be honest this is mostly pokemon focused as well, I have a project in mind and I would think it would be cool to have a simple process to trade and battle. I was also wondering if one could even write a program or plug-in using bluetooth so that the emulator thought the there is a link cable and between the two raspberry pi s they could determine who is master and slave and try to handle the correct timing or maybe convince both of them they are slaves and let some joint program through the bluetooth between the 2 raspberry pis be the master actually, maybe destroying and recreating data on both emulators. ) and not what I am really concerned about. I know it probably wouldn't work a gameboy and emulator because of timing/speed differences between the two (unless you used something like this.

So I've done alot of digging about link cables and link cable functionality about the gameboy and I was wondering if a raspberry pi running an emulator with an extra board and link cable port would be able to use link cable functionality with another raspberry pi using the same setup.(so 2 separate devices, not a single pc running the same emulator 2x).
