Nearly all games are working - at least the ones I can try (8k-Cartridges only). The sprite-implementation is still beta, and the accesses are not 100% cycle-exact, so tricks like Sprite-Strechting/Crunching will not work properly. Badline-stuff as FLI or FLD should work, but it's not tested. Collisions seem to work ok.
I will be off for holidays now, but will come back after 3 weeks with an AD725-Board (for colour video) and some 3.3V - 5V bus switch ICs (for the IEC-Bus, and maybe for a SID-Socket for proper Sound) - then I can start to do real tests with heavy games/demos.
