Home Page Forums MAME MAME The new for 2021 WIP thread

Rob Justice sent me support for a card called the "Grafex-32", which was originally a project published in Radio-Electronics magazine in the early 1980s. It gave the Apple II the then-popular NEC uPD7220 graphics processor and dedicated video RAM so you could do fast graphics. Rob has actually constructed the card for real as well, but as often happens with some of the more obscure cards, the original software for it can't be found. So Rob wrote his own software to exercise the card, and it works 100% on the real hardware. In MAME there's a bit of an issue as-is: our uPD7220 emulation has a hack to make some PC-98 games work correctly which causes issues with the Compis machines and this card. Commenting out the hack got me these working screenshots.
