The wiimmfi patchers that support upnp will also write there (though I don't think any the ones that do unp support gekco codes anyway?). 800002c0-6 (inclusive) are written to by those patchers and then read in game by the payload. As long as 800002c0-3 doesn't equal "UPP1" in ASCII then the payload won't read from it, so it's unlikely this'd break anything
