Cheats engine - Githubissues

fjpolo commented 1 month ago

Cheat module:

Supports 3 cheats (above 4 it bugs, eneds more work). IN theory it should support more if I fix the bug 🐛
Barely based in MiSTer's format: Making your own codes, I kept the 128bit format, but changed the order, and added cheat Number for the engine
Added a Wishbone B4 bus, where iosys.v acts as the master and cheat_wizard.v as a slave. Bus is 128b wide to send one cheat per Write.
I added a menu interface in my branch fjpolo/firmware
There's also a release for quick testing [CheatWizard_3cheatSupport_202040604

I'd appreciate some testing if @nand2mario or @nikitalita have some time :)

I might add some more formal verification tomorrow if I'm felling like it

Branch needs to be rebased

nand2mario commented 1 month ago

I'll have some time to test it this weekend.

Rebase done, updated to latest master hash f06aaf8a88489601a51914325cbd8b9c13501797

So I left the branch at 4 cheats. Again, tested with Battletoads (USA).nes

Module toether with its firmware seems scalable enough but I didn't test more than 4 cheats.

I don't know about FV, I'll probably formally verify the wishbone modules, but not for this PR.

This looks good and I'd like to make more changes. So I'm merging this into a new branch.
