Quote fromso the issue with the patcher wiping your mods is fixed in this version?
The Unpatch button still works the same way, by copying minecraft-<version>.jar to minecraft.jar. Since minecraft-<version>.jar gets created the first time you run MCPatcher, unpatching effectively restores minecraft.jar to the way it was the first time you ran the patcher. If you had mods loaded at that time, they will still be there. If not, you will be back to an unmodded minecraft. This is another reason it's best to run MCPatcher last if possible.
If you're worried about losing your mods, follow these steps before running MCPatcher.
- Load your other mods and get minecraft.jar exactly the way you want it.
- Go into your bin folder and delete minecraft-1.3_01.jar (or whatever the current game version is).
- Run MCPatcher, and the backup it creates will be of your modded minecraft.jar.
