Hello henriquewicz, I had the same problem, I noticed that in the new recalbox version 6.1 there is no longer the "roms / msx" directory for the roms in the es_systems.cfg systems configuration file, I changed my roms + images to the roms / msx1 repository and Everything started to work.
As paradadf says, MSX definitely works - I was playing MSX and MSX 2 games on Monday.
I will look tonight to see if I have the game you are having problems with.
Can you get ANY games to load from your MSX collection?
@cgyed Pour répondre au message que tu as édité avant que je puisse répondre : non je n'entend aucun grésillement dans fba, mais idéalement il faudrait que je prenne le temps de comparer avec MAME au casque.
@leosabino Upgrade to the latest stable version (currently Recalbox 6.0 Dragonblaze): https://archive.recalbox.com/
You will have to back up your files and start from a clean install because the updater will not be able to upgrade from such an old version (there were many changes).
After that, test and return here to say if it solved.
@zing yep, it will more be an issue of drivers (and linux kernel I suppose) than anything else.
What I meant is that, contrary to arm board it doesn't require any porting or specific development, at least theorically, and has a better chance of beeing supported by recalbox one day than any arm board
