A few years ago I bought a professionally done chipped Xec 2.6 PAL Xbox principally so I could use the NTSC dashboard prog scan options but also so I could play some import games. I was a total newbie to this whole thing and didn't have a new larger HDD or anything else added. It took me some time even to realise I needed Enigmah to access the NTSC dashboard options.
After that I had no problem using it for what I wanted except for
NTSC only Myst 4: Revelation. The audio track 'hiccupped' each time a new scene loaded, as though the image and audio loading were temporarily out of sync. I thought this was normal and played through the entire game like that and thought nothing of it.
That was until I accidentally discovered NTSC Myst 4 is actually one of those region free games and will play on an unmodded PAL XBox. Thing is it plays perfectly on a PAL machine ie. without the audio 'hicupp', the BGM and SEs run smoothly and continuously throughout each scene loading process as, no doubt, it was supposed to.
So I have a NTSC game which plays better on a PAL machine than on chipped one meant to and which does play (other) NTSC games correctly.
I'd like to know or try to understand why this occurs. It seems likely it is something to do with the chip as when I turn it off completely and return the machine to PAL status it runs correctly on that too. So is this a known problem with the Xec 2.6 or just an unfortunate unique incompatibility issue with this game?
