The hardware Pyxel simulates seems closest to the Williams arcade games -- Defender, Robotron, Joust, etc. These games had a single 256 x 304 pixel frame buffer, 4 bits per pixel (16 color palette). A hardware bit blitter performed fast block copy operations to draw sprites, scrolling, etc. There was a dedicated 8-bit CPU for sound which could play cool effects, albeit one at a time -- Pyxel's sound generator is closer to the NES, better for music and pure tones. You can see a sample game written in C for the Williams hardware here: http://8bitworkshop.com/v2.1.1/?platform=williams-z80&file=game1.c http://8bitworkshop.com/v2.1.1/?platform=williams-z80&file=g...
