Jumper options:
Set to “LO”: Extended mode is switched off. Console is reset if START+A+B+C are held for 1.5 seconds at the controller pad.
Set to “HI”: Extended mode is switched on. Resets if the buttons START+A+B+C are held for 1.5s at the controller pad. The reset is then held as long as the button combination is held. This mode can be used if you have a switchless mod installed in your Mega Drive/Genesis to switch between the different region modes. Furthermore, the CPU is paused during that time so that the game will not run during this process.
Thanks to ArcadeTV for the initial IGR design which we based this kit upon. The kit also uses Borti4938’s IGR code.
