Good find, Fred. This package actually started my games emulation-fever. I remember I found this once on a warez-cd back in 1996.
These games are runable from a DOS-front end but in fact it runs everytime PC64, an ancient C64 emulator.
PC64 is one basic emulator: it can only read C64 disk-files (*.D64), no tape files, it has only one resolution (full screen) and it used my Soundblaster soundcard to simulate C64 sound.
Nevertheless this package started my games emulation-mania... Has it really been eight years?
