Technical notes

Fork chain: gpSP (Exophase) -> gpSP Kai (takka) -> TempGBA NDS (Nebuleon) -> TempGBA4PSP (unknown) -> TempGBA-libretro. PSP-optimized GBA emulator. No HLE BIOS: SWI calls execute from the real BIOS ROM. The NDS version (ReGBA) added an open-source BIOS replacement (Normmatt), but TempGBA4PSP did not carry it over. Boot sequence skipped by default (PC starts at 0x08000000).
