This is a simple mod to set CPU speed depending on the state of the WiFi switch. If the WiFi switch is down before starting a game, your game will run at 333MHz, if not - it'll run at 222MHz which is the normal speed.
Install by running the eboot included!
Greets to Cpasjuste who loaded the first custom prx on SE-B, the staff at irc.lan.st, and Dark_AleX for creating SE-B!
EDIT: Post updated with WiFi OC-R2, includes a new installer. Thanks Coldbird! :)
