Changed files?

[IAjtuma007]

After all ive tried and fiddled and such, read post after post, the readme and all that jazz... I believe my only problem is that Ive patched beyond the emu. so here is my question...
What files changed that causes the emu not to work after the patch, and where might i get them to 'roll back' my eq folder?

thanks for any help

im really itchin to see this work, sounds like fun, thanks to the developers in advance to me seeing it =)

EDIT: my actual problem is the 'may need to re-run patch program ... da da da...' as this happens on a LAN setup ( thought it was best for testing errors ) my world.exe spews an 'unknown opcode: 0x0286 size:196' followed by a 196 byte dump, then the client is desconnected. Not sure if the data in the dump is important for troubleshooting, but i can post it if necessary.
