|  Re: Porting to Commodore Plus 4 of my game Genius, memory/bitmap mode questions..
Oh my GOD! Yeah I probably forgot to zero the memory RAM from AF00 to AFFF which is used as
memory for the player.
I make some ORA $AF00,X of FF12 and probably on VICE and at times the memory is filled with ZERO and
some times not, I assume in real hardwere there might be random values at startup and this surely
would have ruined bit 2 of $FF12.
Correcting and testing now! Thanks GAIA a lot for the help! 
EDIT:

Here's version 02, works in YAPE and PLUS4EMU correctly so far...still testing. There were a couple of memory areas that needed to be cleared at startup and some premature routine calls that were causing damages that were not visibile in VICE.
Still music is playing a bit slower in YAPE, really don't know why :)
Thanks for any real hardwere test feedback! :)
