I'm using the android Shield TV and for some reason this specific game won't work right with save states but only if I swap games or unmount the storage. If I leave the game in it works fine but I can't put another game in and come back to my game in progress. I just start from the beginning again. The rom will work but if I try playing it off the cart it won't. I cleaned it 3 times with brass polish and alcohol and the save state folder is not on the cart. It's on a usb thumb drive and I have tried the internal storage. Every other game works though. I've tried the latest mupen64 nightly and mupen64 in retroarch. Oh and my Retrode 2 is on the latest firmware.
