i know you can flash tsop using 007/evox gamesave exploit. i'm not sure if any of the bfm stuff would work or not, anybody else?
however, i can say that raincoat is not the only way to flash it, i've done quite a few boxes and I always just load up a memcard with the 007/evox gamesave exploit with a x2 bios of appropriate size loaded in it, use xboxdash to transfer to hdd, then use 007 original game to load evox dash and flash.
just a note, the bios folder in this case is embedded in the gamesave directory in the hacked 007 gamesave.
