People...
I'm in trouble. I just want to set the sprites on Screen 6 and I'm finding
some trouble.
I use the BIOS functions to find the Sprites Pattern, Attributes and Color
addresses, and they return the right address.
So, I use the following to copy the Pattern Table from RAM to VRAM:
LD DE,(SPRPTR) ; Points to DEstination Address (Pattern Table on VRAM)
LD HL,SPRITES_PAT ; Points to source Address (Pattern Table on RAM)
LD BC,8*2 ; 16 bytes (2 sprites, 8 bytes each one)
LD IX,LDIRVM ; Points IX to BIOS function
CALL CALLBIOS ; Call BIOS
The copy actually runs "almost" fine. LDIRVM really writes 16 bytes
starting from SPRPTR (on VRAM), but it doesn't write the same bytes
on SPRITES_PAT (on RAM). Actually it writes JUNK on VRAM. I don't
know what to do. Any ideas?
