I just purchased an Xecuter2.2 PRO mod chip. will the bios that comes with it allow me to back up my games? I've been reading many many many posts but it still seems unclear. Thanks for the help
nope. flash to something better. m7 or 4981 are the latest. Cromwell is put on chips because they are legal and make it easier to flash bios.
no matter what your chip is the bios are the same and allow you to do the things you do. Both of the bios i named are pretty stable and are the most recent and popular.
the xecuter chips all bring the cromwell bios which is basically what allows you to flash your chip with the hacked bios such as the xecuter 4981 or the evox m7. i think the xecuter bios are more advanced than the M7 bios and is what i would flash with.
