The mayn diff. between PAL and NTSC is the higher resolution of PAL... PAL has about 600 horizontal lines and NTSC 500 (a bit more or less). Most games are from JAP, so those must be "fixed" to fill the whole screen in PAL-Format, otherwise something is missed = black borders !
FFX PAL isn´t that bad, but if it´s the same problem with FFXI, than I´ll buy the US Vers. of that game !!!
