Hi all,
What is the simplest way to load a file in VRAM using assembler on MSX2?
I found the BLTVD instruction in the Sub-ROM but I'm not sure how to use it.
I'm working on a 32K cartridge (Page 1-2) using 16K of RAM (Page 3) so I don't handle any memory page switch.
To access the Sub-ROM functions, have I to change manually the Page 0's slot?
Also, I found in the MSX2 Technical Handbook that the NX/NY parameters have to be in the data to transfer... in what form?
I added 2 WORDS in front of my image with width+height information but I'm not sure this is right and I don't miss other information.
Last, I would like to know if there is any initialization to do before to be able to use Sub-ROM functions?
