Tnarg,
Yep, the QuadMod is fully compatable with the Modpack (TDM), just unzip it into an empty folder. Rename the "QuadrantTypes.txt" and "SystemNames.txt" (add the 'old' or 'original' prefix to them or somesuch) and copy the two text files named above into your TDM-Modpack/Data folder. You may also want to Open/Edit the 'Settings.txt' to alter the Max Number of Systems line to bump the # to 150 or 200 to make the 'Maze' type maps really maze-like
. The only files that are really changed in the QuadMod are the QuadrantTypes.txt, the SystemNames.txt(though you can use any old SystemNames.txt, I just have mine full of names I thought were 'cool' IMO). All the old system types are already included in the QuadMod so you won't be losing anything that was not already there.
For added fun the MountMod is fully compatable with the TDM as well, just rename your 'CompEnhancement.txt' file and subb in that same file from the MountMod into the TDM-Modpack/Data folder and volia! Instant new mounts (The AI will use most of them as well, prepare for Destroyers that have ER weapons, Cruisers that have Pulse Meason BLasters!!)
Need any more help, I (Or someone else) will be more than happy to oblige......have fun
