HedgeArcPack - Broken Lost World PAC Generation

[Sonen10]

While HedgeArcPack in its current forms appears to work fine with most games, generating PAC files using the Lost World option causes the generation of broken PAC files. It can currently unpack files from the source games fine, but trying to use PAC files generated by the latest version of HedgeArcPack causes the game to refuse to load them. For instance, unpacking and repacking Sonic's archive causes his model to not load on the world map and crashing the game when loading into a zone. HedgeArcPack is fully able to extract these broken PACs too.

Attached are two zip files for reference. One contains the original Sonic PAC files from Lost World, the other contains PAC files with the same contents but repacked via the latest HedgeArcPack.

Thanks very much for reporting this, and especially for providing samples! I'm currently finishing up a rewrite of the packfile handling code in HedgeLib, which should also fix this issue. I'll look into this and try to discover its root cause to make sure it's fixed.
