> Chrono Trigger Reimplemented ports the USA SNES game to handwritten C and compares ported routines frame by frame against the original ROM. Its development runtime combines native routines with generated C and a 65816 interpreter while the attract sequence, field, menu, event and battle systems are being ported.
