Technical notes

Never-completed fork of PCSX-ReARMed targeting general PC hardware. Experimental, abandoned since 2018. HLE BIOS built-in: if no BIOS file found, core warns and falls back to HLE automatically. BIOS search order: scph1001.bin, scph5501.bin, scph7001.bin by exact filename, then scans system directory for any file matching "scph*" (case-insensitive) with size == 512 KB. No region detection, no hash validation. First valid BIOS found is used regardless of region. .info declares scph5500/5501/5502 but code explicitly searches scph1001/5501/7001 first.
