retroarch msx cheats

Hello, I understand, but how can you compare the first photos that belonged to Retropie and the last ones from Batocera? Differences can be seen.

Leaving aside the menu driver difference (XMB vs. Ozone), the only difference I see is the version of BlueMSX - RetroPie has a newer version (Jul 2022) than the other systems (Feb 2022), which doesn't account for much, since there's only 1 commit between the 2 dates.

Ozone

If you mean ozone , I changed it to that one, Regarding the bluemsx version, I don't know what can influence it, Sorry I'm new to raspberry

edit: whether it works or not , nothing happens , it was just an appreciation , I still prefer retropie

As soon as I have a clear idea, I will try lr-fbneo that I have read in the forum apart from the partner that was mentioned

@Folly @mitu
It took me a while to be able to try and work fbneo for msx because I've been very busy, it already works for me but no matter how much I've searched I haven't found a solution there are no fbneo cheats for msx1 only for arcade

@barbudreadmon

Can you help @wicketewoks to get msx cheats working on lr-fbneo ?

Do these cheats work on lr-fbneo ?
Or are there other msx cheats for lr-fbneo ?

Those cheats aren't meant for FBNeo.
Afaik, nobody wrote msx cheats for FBNeo.

@barbudreadmon

Thanks for you reply.
Ok, so that is a dead end too.

Until someone discovers how we can get it working with lr-bluemsx.
Using Mame and lr-mess described in this post seems to only working option for now :

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.

@barbudreadmon
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.

@barbudreadmon
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.

wicketewoks

@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
