Game Boy/Game Boy Color[edit]

  • Game Boy/Game Boy Color (rrgbc V0.10): Great GB/GBC compatibility, supports the APU. Current version found exclusively in Wave.


  • Chip-8 (WAVE-8): Supports base CHIP-8, as well as SuperChip 1.1, hires CHIP-8, XO-CHIP 1.1(full audio support), MegaChip(no audio), HyperWaveCHIP-64, and HYPERCHIP-64(no audio). Exclusive to Wave.


  • Game Boy Advance (REGBA V0.0.5): Expect little to nothing to work, especially not any retail games. Unlike the other emulators in Wave, REGBA expects ROMs to be in base-64 format. Available separately. Removed in V1.0.0.


  • Nintendo DS: Simple homebrew like TinyFB runs, main issue is actually memory constraints. Doesn’t play any retail games. Available separately.


  • Nintendo Entertainment System (Cool NES 2.4): Compatibility is the same as CoolNES 2.4. Available separately.


  • Bytepusher (1s1s BP): Limited to 200KB of memory due to the Scratch list limit, runs fine with 16MB of ram in Turbowarp. Available separately.


  • Space Invaders (SI8080 V1.0.1): Passes all cpu tests except 8080EXER/EXM. Plays Space Invaders with minor artifacting.

Converting Roms[edit]

  • Scratch does not allow you to upload files directly during runtime, so you have to convert the desired rom to either a hexadecimal or Base-64 format string depending on the emulator.
