An edited version of my Hokuto no Ken (the first game of the series) for FCEUX to work with Fist of the North Star on BizHawk.
  • Ignore the "template" comments, as I had to change the format for BizHawk (cannot read word, have to use read_u16_le or something)
  • The memory variables are very similar between Hokuto no Ken and Fist of the North Star, so the following variables are OK: Cam X, PX, PY
  • The following is not implemented so far: Enemy/projectiles IDs, these being alive
  • There's also a bad quickfix on the bottom of the script which doesn't cares about BizHawk loaded a ROM, so loading this script twice will closes BizHawk... will fix it in next version

This template features an example to NES Rush'n Attack
