GSE vs ProFaceFinder

GSE is a free emulator for Game Boy, Game Boy Color and Game Boy Advance, intended primarily for speedrunners. It uses Gambatte for the first two systems and Mesen’s GBA core for Advance. The emulator runs at approximately 59.7275 FPS and uses clock synchronization for consistent frame pacing and low input lag. An optional Low Latency Mode can further lower input lag, though frame pacing may become less consistent. GSE records input logs for each run as a secondary source for verification and provides 100 savestate slots in ten groups. It supports compressed ROMs in 7z, rar, tar, gz and zip formats, and controller support through SDL3 includes GameCube USB Adapter and Switch controllers. Discord Rich Presence is available but off by default. Bootrom or BIOS files are required. GSE runs on Windows, macOS, Linux and Android, subject to minimum operating-system and library requirements. Cheat-code support and other features not useful for speedrunning are omitted. The project is distributed under the Mozilla Public License 2.0.
