  • 648dd180ed CIC 👌 Nabile Rahmani 2017-10-08 00:38:30 +02:00
  • 933423373d Fixed the high-level emulation of the PIF ROM. The previous source wasn't accurate enough, so I stepped through the real PIF ROM and recorded all memory writes and final CPU register values, with the intent of restoring the machine state. This code should be revisited in case memory reads do affect the system, or if the CPU emulation at the time of this commit is inaccurate. Nabile Rahmani 2017-10-06 10:59:43 +02:00
