Re: Little Lode Runner was Re: 48K stage-loaded to 64K single-load?
Another followup...
The current level is stored in 0D00-0DFF and the high score table in
1F00-1FFF.
I am currently trying to detect disk i/o targetting these blocks of
memory. If possible I want to simply eliminate i/o on 1Fxx - this doesn't
need to be saved, and I keep a blank image in the memory dump - and I can
rework level loads once I find out where the code *is*. The demo levels
are already held in memory (9F00-A1FF).
The first objective will probably be to use one bank of the language card
- allowing (depending on what the code uses as its "end of game
conditional", I think it's a blank level) about 46 levels stored there.
Add another bank, and that number rises to 62 - enough to comfortably hold
the level set for Championship Lode Runner. I don't think it's possible
to free up enough memory to hold 150 levels (the whole disk version)!
Afterwards - if I can create Little Lode Runner successfully - I will
probably resume the original ProDOS-8 Lode Runner project.
