PS1:In-Game Reset (IGR)

In-Game Reset (IGR) mods are a simple board that allows you to press a button combo to reset the console. There are multiple IGR mods for the PS1 including ones sold by Will's Console Modifications, RetroGamerStuff, and ConsolesUnleashed. It is also open source and available on OSHPark.

Installation
While each different board may be different, generally they are in a Quick Solder Board (QSB) format that installs onto a controller port's pins with a single wire connected to a motherboard-specific point. Instructions for this install are from Will's Console Modifications.


 * 1) Place the In-Game-Reset board over the controller port pin holes and solder it in place. You can also install on port 2 instead, or one on each.
