I'm running PKHex on my handheld R36S Clone (Ark 2.0). It saves as .SRM If I convert it to SAV PKHex picks it up. The problem is trying to get the updated file back on the device. It exports as .SAV & I changed file extension to .SRM. When I boot up the device it can't see any save states and doesn't have continue game as an option. Only "New game". Any help appreciated.
