I received a bunch of screen$ files in a tape file. I want to read and show then at 25 fps. This is possible in emulator, because it loads files immediately. I have got this code:
10 poke svar &33,1 20 load “”screen$ 30 pause 2 30 goto 20 The problem is that screen$ files have got color palette at the back so the new image is first loaded and shown with old palette and then the new palette is set. Please somebody help me fix this annoyance. I need to keep the current image with its palette visible until the new image is read from tape, and then show the new image with its palette immediately. Can this be done in Sam Basic? Or can somebody help me to make the correct assembler code to do it? I know exactly how it should be done, but I haven’t programmed in Z80 asm for 15 years. I would use two screen buffers in separate pages, and a short asm code would switch VMPR to the new page and set the new palette at once. Something like this: 10 poke svar &33,1 20 load “”code 131072 30 call 131072 + &7000 40 load “”code 81920 30 call 81920+&7000 30 goto 20 Z80 ASM PROGRAMMER WANTED! :-) I need those few instructions to be placed at offset &7000/&f000.
