I've tryed the disk2easyflash program but it doesn't work. What do I wrong?
If the description of your problem would be a bit more detailed, possibly someone could help you.
Note that really only a few programs work with this tool. The usual and reliable way to make an EasyFlash version of a game that has more than one PRG file is to patch it.
Where can I find a complete list of working d64 files for the Easy flash cartridge?
There is no such list. Some programs which are known to work are in this thread possibly.
