Which sprite/memory functions to add to ROM?
Posted: 02 Jul 2018, 16:21
I would like to add some sprite and/or memory copy functions to an upcoming (very minor) ROM update for the kit. Any suggestions? On the short term (this week), I'm just looking for SYS functions that are well-tested and stable already, preferably no truly new stuff. I’m a bit at loss about the status of these in Contrib:
BTW: the video loop has been reordered a bit to enable more retro modes and speed levels. This will make it easier (in ROMs even further away in the future) to assign blitter-type of functions to certain scanline types. Now I just use it to get more vCPU cycles, but I see room to use it for other purposes.
- SYS_SpriteRow_118: Does 4x4 block copy?
- SYS_SpriteCopy_118: What’s the difference? Same?
- SYS_ClearRow32_56: Looks useful. I can add this..
- SYS_BlinkyBlast_142: Doesn’t sound too generic... But it is cool.. I'll sleep on it
- SYS_DrawPixel2x2_32: Small but usefull
