 Re: Porting to Commodore Plus 4 of my game Genius, memory/bitmap mode questions..

Hi Twinspirit32,

A few posts earlier gerliczer recommended the Ultimate Map by SVS, I'd like to echo this. The answer to your question can be found there very quickly.

To be specific, The CLALL system call is on $032A/$032B, so the same technique should work. Another way to do it is hook $0302/$0303 (I think this is the most common way to do it).

In addition, I'd suggest that if a disk image only starts with LOAD"*",8,1 - that is a bug, or at least a major inconvenience for the user. DLOAD should work, and in fact, with minimal amount of work it's possible to make a small loader file which works both ways (DLOAD+RUN or LOAD"*",8,1 autostart).

One more note (my biggest pet peeve): don't make it PAL only happy

Good luck with your port!
