I have only 8 and 16bit consoles systems. Full Sets and All JAP games are patched personally by me with at least "playable" patches. I love those games so much!
Thinking to switch those on Retropie and start modern consoles and systems with launchbox, but i don't know as the way LaunchBox handles multiple roms (for me, mostly translations) is unmatched and it's the reason i happily moved here
