Boktai: The Sun Is in Your Hand
Game Boy Advance · 2026
Community GBA recomp that drives the game's solar sensor from real local weather instead of the original cartridge hardware.
BoktaiRecomp is a community project by Shy that brings Boktai: The Sun Is in Your Hand to gbarecomp. The original cartridge had a real solar sensor that gameplay depends on; this project substitutes it by driving the sensor from real local weather.
What works today
The v0.1.0 "Boktai builder" release (2026-08-03) ships BoktaiBuilder, which compiles the game locally on your machine. The release includes a Steam Deck flatpak plus Linux and macOS builds.
Enhancements
The weather-driven solar sensor is the headline: sunlight in your area becomes sunlight in the game, no cartridge hardware required.
The release explicitly contains no game data; BoktaiBuilder builds from your own legally dumped ROM and GBA BIOS.
