LPFaint99 b20858adb3 System Menu Region is now detected based on the Title Version in tmd
Title Version and region char of currently installed system menu are now listed in the menu as well

Which means disc channel will only show pal discs if it is a pal nand dump; ntsc nand dump will show ntsc discs, ntsc-j nand dump will show ntsc-j discs
