Re: A little bit of Mode 9 insanity
I changed the code to modify the palette. However the top half is still black. The bottom half now changes color as would be expected. m90_split = 112; for (unsigned char i=0; i < (25);i++) palette[0] = i*10; for (unsigned int i=0; i < (400);i++) vram[i] = 147;

Re: A little bit of Mode 9 insanity
OK I think I figured out what I was doing wrong with the m90_split. I am trying to make a quick test to see if I can change the screen to lines. I think this code should make vertical lines. However it just makes the top half of the screen black. m90_split = 112; for (unsigned int i=0; i < (400);i++...

Re: A little bit of Mode 9 insanity
I'm getting a Symbol 'm90_split' could not be resolved, when trying to activate the new mode. For writing to RAM tiles, do I use settile, or is there another method?

Re: A little bit of Mode 9 insanity
Sorry I've been a little busy lately. The newest fix you incorporated, allows mode 92 to work in standard mode. I haven't attempted to convert a picture yet, I'm hoping to do that later today.

Re: A little bit of Mode 9 insanity
adding the .space 2, didn't help. It seemed to make things worse. The screen was mostly black with that change. The map file has vram at 0x0080010e.

Re: A little bit of Mode 9 insanity
I'm running eclipse for the ide. If I set it to mode=90, and do a clean then build everything works fine. Then I set it to mode=92, do a clean, and a build. I get the results I posted before. Then setting it back to mode=90, clean and build, problems disappear. Since I can make the problem appear an...

Re: A little bit of Mode 9 insanity
I installed the new kernel, thanks. However There is some screen corruption. The whole screen is shifted the right, and loops around. Also the top line and a quarter are damaged. Perhaps the whole screen simply starts at the spot on the second line, which causes every line to be off. roguze_92.png R...

Re: UCC2016: The Uzebox Code Challenge returns!
And kind of working on mine at the same time, with the stuff you've been putting into your mode 90.

Re: A little bit of Mode 9 insanity
I already load some of the game content from SD. The 2bpp 120x112, would work great. Not much would going on in the game itself during the enhanced display, so you could use more cycles if needed. I would only need to check for button presses, to exit this mode, or switch to the next image. I am at ...

Re: A little bit of Mode 9 insanity
Is there enough time in HSync to load some of the graphics? Such that an image could be loaded 120x112 at 4bpp. Perhaps preloading half of the image before the display routine, then replacing the lines as they are displayed. If half a line could be loaded on each line, then everything could be displ...
