Use the xdelta given to you in the .rar
Xeno.xdelta is for Xenophobia roms while Clean.xdelta is used for clean roms
Then patch the rom (always keep a backup of the original rom file)
These two patches work on clean/xeno roms. DOES NOT WORK ON EUROPEAN ROMS.

*This patch was tested on official hardware; however, it should work fine on emulator as well*
