Memory Pit by Shutterbug2000
(added lower firmware & korea support versions contained here - zoogie)

256      -  Use this version for Korea and < 1.4 for all regions (try 768_1024 if your non-korea system doesn't work).
768_1024 -  Use this version for 1.4 - 1.4.5 all non-korea regions.

Otherwise, directions are the same as the standard pit.bin from shutterbug2000's release thread:

If one of my versions isn't working, go ahead and post in that thread about it.

Note: Chinese iQue isn't mentioned because I haven't encountered any users from this region yet. But try 268, who knows it may work.
