- CPS1 arcade modders and Aseprite pixel artists
- Worth noticing
- The page lists 29 playable titles and says the emulator was written from the hardware up, without an emulation library.
Field notes
The capture step is described as recording sprite poses and scrolling tiles during gameplay, while the editing handoff preserves tilemaps and palette data in Aseprite files. The implementation notes name a Motorola 68000 interpreter, a Zilog Z80 audio CPU running in a Web Worker, and YM2151 synthesis via WASM; these are homepage descriptions, not independently tested results.
