@neauoire is this something that can be generalized easily for UI at uxn scale? i did this repainting management once in flash when i was manually blitting the game sprites, but it was easy because they were all 16px or 8px sized and were regular actionscript 3 objects
@dantescanline do you mean like, I should implement it as part of each emulator? It's sort of per-device, like for example, sdl and x11 emulators can do coordinates selective redraw, but something like the GBA or the playdate, it's per screen row, so the same debug routine couldn't be used for both
