MS Change

For spoofing some games checking (such as "xxxのディスクがセットされていません" error), this plugin can emulate inserting or removing Memory stick with key combo.

The project is developed on PSP3000 6.60proC2 CFW, and also tested on PSV2000 Adrenaline 6.61pro.

Usage

1. Add ms:/seplugins/mschange/mschange.prx 1 in ms:/seplugins/game.txt config file and then reset vsh
2. Start a game, accroding to the game instruction
   select+up to emulate inserting memory stick
   select+down to emulate removing memory stick
3. After that, most of games create a save on the memorystick, then you can disable this plugin

Build

1. Download pspsdk or minpspw(windows)
2. set env PSPSDK to the sdk path
3. use build_mschange.bat or build_mschange.sh to compilethe project
