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

this topic is already in the forun... and already closed...
plis searchs a bit .....

not very helpful if you dont give the link

i searched before posting this topic @ mrc and google. i don't see closed topic relating to screen 0 vram copies in this forum.

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.

i was looking for the link

but MRC has a very limited search engine

and the development forum has not subcategories

after checking 20 pages i abandon unsucess the search

yes fly, i did the same search and manual search but did not find anything

@BiFI: does this work for screen 0 !!??

ill try to mess with your information

ahaaaa.. i know how i can do it in ML. but is there are way to do it in BASIC too? at least i dont see a way to load cpu registers from basic without inline ml.

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

the

isnot what i am looking for , but about VPOKE/VPEEK is already there

DarQ, those BIOS routines work with every SCREEN mode.

i read the entire topic you link to.
anyway. i can at least have the upper part scroll up, and the lower part keep intact.

i will try to mess around with copying vram in screen 0

thank you all

i will search with tags

jajajajajajaajaj

is better donot to have a search engine... than to have one that makes loose the time

no tags doesn't work... never mind....
