How did you download them all from wayback ? I tried to use teleport pro and it just refused to gather all the zips (from your link, but i do know they work cos i downloaded a few manually).
When all these sites were active i was a bit of a SW map horder. I recall leeching hundreds and the majority of the map packs were from my own backups. Had to dig out a rather old dusty cd
Many people contributed too and whatever sites i could find that still existed i rechecked and leeched from. Including yours.
This means that i probably did include virtually every map from that gameleader site. All yours, all my backups, deleted all dupes and shared them here. For this reason i believed the pack to be pretty complete.
I can say that many zip names often had a different map filename inside. So the corrupt zips you have i.e. Bridge.zip isn't necessarily bridge.map inside and may still be included. Hard to tell though but i'll be interested in a full zip of files you manage to find and i will check and update the packs. (would be great to have access to a single huge zip if you could ? I could let you know when i've got it so you can take it down again.)
