Star Haven
A native Nintendo 3DS port of Paper Mario (Nintendo 64), built from the Paper Mario decompilation. The game's own C code runs on the 3DS; nothing is emulated.
Star Haven contains no game data. You need your own Paper Mario ROM (EU or US).
Install
- On a 3DS with custom firmware, open FBI → Remote Install →
Scan QR Code and scan the code on the right. It always installs the newest release.
