Boktai: The Sun Is in Your Hand
Game Boy Advance · 2026
The cartridge had a solar sensor. This community GBA recomp feeds it real local weather instead: sun outside, sun in the game.
BoktaiRecomp is a community project by Shy that brings Boktai: The Sun Is in Your Hand to gbarecomp. The original cartridge carried a real solar sensor that gameplay depends on; here, real local weather stands in for it.
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.
