Kenshin,
This is, of course, not a normal behaviour!
WindowsXP (and Pentium IV) is one of the systems used to test mGalaxy...and the whole XML generation process is achieved in about 1min!! (on a whole romset, as you!)
Some questions to try to help you sort this out:
- Did you install "Microsoft's .NET Framework 4.0" < The most important thing!!
- Can you see the "xmlout.xml" file in C:\Documents and Settings\{username}\Application Data\mGalaxy\xmlout.xml folder? Is it and empty file..or not?
- Could you try to temporary move all the roms, just leaving a couple one and see what's happening?
