Today I test the “Biohazard 2 - Value Plus (Japan)” and load the game with Reicast WinCE. I’m sure the bio2 save is in the vmu save card,But the game have no save. Later, it was found that all the saves in the memory card had been deleted. Other games can be imported into the save, but bio2 can not. As long as the game is load, the memory card will be formatted.
I think the VMU stuff is still in flux a bit, so yeah, you’re likely to encounter bugs.
