1)Check your BIOS files.at Menu,at Menu>Game Setting>MISSING BIOS>Play Station 2.If have any missing,search and download it,put on /recalbox/share/bios.
2)Download 3 game for test.Metal Slug Complate,Metal Slug 3D and God of War.Download games from like Coolrom(That's me first select)
3)If you can running MS Complate,program is no problem.
4)If you can running MS 3D but fps not better(n<30/s),program is good,hardware not better but can play game like RPG or AVG.If fps much more 30,ACT and FGT not bad.
5)If you can running GoW first map on rain and fps is full(n>=60/s), all game you can play it!
6)If you can't running MS Complate,and your BIOS files not have missing,just your hardware is too low for running program.
7)If 3 games not have problem but you download other game can't running,just switch a source and download again.
8)Some games can't running,I don't know why,pass it.
