I don't think there are any other 2K VCS games that use BRK instructions. ;-) There are some 2K games that use addresses at $f000-$f7ff and at $f800-$ffff interchangeably, IIRC. For those you have to double the binary to 4K before you can use them on the SC. But since that doubles the transfer time and isn't nessessary for most 2K games, we leave that to the user and only map the 2K in the appropriate spot. If the person from AA used a 4K EPROM, he probably doubled the binary to 4K as well. If he used a 2K EPROM, then one address line would be ignored, and the 2K ROM would be mapped into both slots automatically. > Ok, I have attached a new version. Does that work on a SC too? I couldn't test it much. The most current version of Playbin for the Cuttle Cart seems to have a problem when transferring games in SC mode. I tried an older version of Playbin, and version 1.04 of your game plays fine on the SC. The older versions crash when the joystick button is pressed. So I think you fixed the problem.
