Technical notes

Fork of higan v106 by hex-usr, renamed at byuu's request. Dot-based PPU profile (cycle-accurate, most demanding). Current nSide source blocks accuracy build (#error at libretro.cpp:39, libretro-sfc.cpp:8). Core is orphaned from an older nSide revision. Coprocessor firmware loaded via icarus manifest system from system_dir. File names follow icarus convention: {identifier}.{content}.rom. SGB emulation loads from SGB1.sfc/ or SGB2.sfc/ subdirectories, with fallback to SGB.sfc/ and Super GameBoy.sfc/. SPC700 IPL ROM (ipl.rom, 64 bytes) compiled into binary. Accuracy and balanced cartridge loading code is identical.
