you can hex edit the xbe to change the crc's to your roms crc's get a hex app and open the xbe and search for the crc but in reverse (eg: crc E5794ACC, you look for CC4A79E5) after you find it, type in your rom's crc in reverse order save and try the xbe out i've done this for my rom on that fbax you posted and they work great except for the rotd since it uses 2 p roms and not the one p1 i got in my current kawa-x se I'm still waiting on n30ghost's fbax plus which will use kawa-x se roms and even add the 2 games kawa-x never got (v-liner and jockey gp)
