So i bought it and started playing. I have only a misterfpga and with the setting as c128 or c64 works just fine. With cpu normal 2x/3x/4x all good. If i enable the reu 512k/2m/16m or georam 4mb, the game see the expansion but then it crashes after the piggy18 logo.
I understand that misterFPGA may not be supported but just wanted to inform you of the issue.
The game is nice and responsive, played on an old color TV.
