you can be sure to make it go elsewhere by changing the gameid in param.sfo, the whatever.conf, the text in the .conf, and the folder with USRDIR and everything in it...it will install to "whatever" not the real gameid..the "dev_hdd0/game/ABCD12345" just means thats where you have to place the USRDIR....
