Hi,
The subject explains it all. But for good understanding:
Can i copy VRAM-VRAM in screen 0? Or RAM-VRAM and VRAM-RAM?
Many thanks in advance

VRAM to RAM: BIOS CALL $0059
RAM to VRAM: BIOS CALL $005C
input registers are similar to LDIR
VRAM to VRAM: first copy to RAM, then back to VRAM
with the MSX2 graphical screens a VRAM to VRAM copy can be done with a VDP command.

well as you mentiones screen 0 and as previous in other thread you mentiones that you want a text scroll to do two independent text scrolls in the screen 0 at the same time... i was looking for a routine in source code and in compiled version that allows scrolls in the 8 directions... written by me and hidden in some thread...
as the thread on the forun don't give much clues about what is being the name... like typical topicname "I need help." and the search engine don't allow to search in a specific forun or subforun... mixing all with newspost results...  hard work

DarQ, those BIOS routines work with every SCREEN mode.
