Hi everyone!
It's been a while (8 years approx![:D]( "Very Happy")
) but I'm again approaching a possible port to bbc micro of my game GENIUS...
I was thinking to avoid shadow memory and stick to BBC Micro B+ 64k and Master as minimum requirements.
I've been reading docs and references but still have some confusion on how to actually set up a situation where I have
sideways RAM active full time to get $0000-$BFFF available as ram.
Anyone can help me with the correct Assembly code to handle register switches for enableing RAM $0000-$BFFF at startup and keep it available full time?
When this is activated, can I use DFS to load some binaries in area $8000-$BFFF using the standard DFS calls available from assembly?
Thanks a lot!
