I made a modded version (details soon) of the Xecuter 3 bios to theoretically boot on all chips (it was tested on a 1.0/1.1 TSOP, SmartXX and Xenium chip). It is 1024k bios so you can't flash it on a 1.2-1.4 tsop. (Config Live won't work because most if not all except x3 chips don't have a dedicated EEPRom)
Warning: This modded version hasn't been tested on every modchip so don't try to flash it, if you have no way to recover as it might could brick your chip.

Thanks to xbox7887 for testing it on his Xenium Box and 1.0/1.1 TSOP.
