retroarch msx cheats

Using Mame and lr-mess described in this post seems to only working option for now :
https://retropie.org.uk/forum/topic/34117/retroarch-msx-cheats/2

FWIW, while time consuming, it's usually pretty straightforward to transform MAME xml cheats into cheat.dat entries compatible with FBNeo and older MAME. I suppose it could even be automated through some python script.

I have continued doing tests, batocera 36 the cheats no longer work in bluemsx, in 35 they did work

It appears cheats are flagged as unsupported for the bluemsx core for some reason : https://github.com/libretro/libretro-super/blob/master/dist/info/bluemsx_libretro.info#L21. It might be a typo ?

You might be able to get cheats working again by modifying your local bluemsx_libretro.info file (replace false by true) ? Those values in info files used to be ignored by retroarch, but nowaday some of them disable/enable features, like https://github.com/libretro/libretro-super/blob/master/dist/info/bluemsx_libretro.info#L20 which controls savestates/rewind/netplay/runahead availability.

Thanks for your answer, I'll try it

edit: I have seen that the script is here /opt/retropie/libretro cores/lr-bluemsx/ but how do I modify that to take them into account?

The cheat related functions in the core source are just stubs, maybe that's the reason cheats are disabled in the core info.

Retroarch's cheat system can also use https://github.com/libretro/blueMSX-libretro/blob/e21bf74bddb79ad1bbe20b4d964e7515269c669b/libretro.c#L1273-L1284 to directly access the main ram of the emulated system, and since cheats apparently worked with older retroarch/core versions, i wouldn't worry too much about the cheat stubs.

Not sure i understand your question, you just need to edit the file.

because I don't know where the bluemsx file is, but what file are you referring to, I'm a bit lost

The core info files are in $HOME/.config/retroarch/cores or - via file shares - \\retropie\configs\all\retroarch\cores. Just like a regular RetroArch installation.

@mitu
thank you so much

I only see 1 core_info.cache file

mitu

@wicketewoks Update your RetroArch and the rest of the packages.

@mitu
done, they already appear to me

@barbudreadmon
modified the file, set to true and tested, the cheats do not work

You should update your RetroPie-Setup script first and then update the packages.

wicketewoks

@mitu

I did that and it already shows them

I have no other idea, it seems weird that it wouldn't be that, it doesn't seem the core had any change about cheat support so a change in retroarch and this info file stuff specifically seemed the most likely.

don't worry about that, thanks
