IPL Replacement

The original RTC/IPL Mask ROM IC on the Gamecube Mainboard

IPL Replacements were the first modchips for the GameCube. Basically, the Mask ROM which contains the IPL could be overridden to load unsigned code from a separate flash chip on the EXI bus.

Technical details on the replacement can be found in YAGCD Section 2.8.3

Many IPL Replacements also replaced the disc drive firmware by sending a "sudo password" from the Gekko, namely MATSHITA DVD-GAME. These DVD-compatibility IPL Replacements were succeeded by drivechips.
