As far as I understand Sam's Jounrney's cartridge is a so called Gmod2 cartridge and has 3 save states so you can save the game progress on the cartridge itself. When I tried the Cartridge image in my TC64 V2 it did not save the game progress. I had to use the D64 version if I wanted my game progress saved. Is saving to Gmod2 cartridges not supported by TC64?
Also, I bought the digital version of L'abbaye Des Morts. It comes with a cartridge image, one regular D64 and one D64 for SD2IEC. None of the D64 images seemed to work on my TC64V2. Started loading the game and just gave me an error. Cartridge image worked fine though. I connected an SD2IEC to my C64 and the D64 for SD2IEC worked just fine. So is this a know issue with the TC64/TC64V2? All other D64s I've tried so far works fine.
