v2.2.0 PAL & NTSC

Risa Tracker for the NES

Risa is a music tracker for the Nintendo NES, shaped around familiar song, chain, phrase, instrument, table, and groove editing pioneered by the renowned Gameboy tracker Little Sound Dj. It targets real NES constraints while keeping the workflow close to handheld trackers.

Risa allows you to utilize the capabilities of the 2A03 APU and in addition to that, the two pulse channels provided by the MMC5 mapper which is used by the software.

The tracker is still in early development, so expect bugs and data loss - back up your saves often! If you encounter problems, please send mail to risa@laamaa.fi.

Latest builds v2.2.0

The easiest and most reliable way for using the ROM image is Mesen NES emulator, which is used for development also. For using the software with actual NES hardware, the Everdrive N8 Pro flashcart by Krikzz is recommended.

For trying out the tracker quickly, there is also a browsed-based emulator available with links below.

Use PAL for most European NES timing targets; use NTSC for North American or Japanese NES timing targets.

Before using another emulator for real projects, make sure it preserves the full 64 KB MMC5 save file. Some emulators and cores are known to mishandle MMC5 save RAM, which can truncate or corrupt saves and lose song data.
