FAQ

Q: What the hell is a Nilmod? How do I install this? AAAAAAAAAAA??!?!?!!
A: First of all: you can install NilLoader alongside any other loader (including Forge, ModLoader etc.)! A Nilmod is a mod that is loaded by NilLoader. You should install NilLoader first and then put NilFix in either the usual mods folder or in the dedicated nilmods folder (recommended!) in your Minecraft instance.

Q: I have found a bug in 1.2.5 itself or some mod. Can you please fix it?
A: Well, I will try my best! Please report it over at the mod's issues.

Q: I have found a bug in NilFix itself. Can you please fix it?
A: That's unfortunate! Please report it over at the mod's issues and I will fix it, of course.

Q: I don't have some of these mods installed. Will this mod still work?
A: Yes, NilLoader only applies my fixes if the corresponding mods are present.

Q: I want to disable certain fixes. Is this possible?
A: Yes! In your Minecraft instance folder, go to the config directory and open the Nil125Fix.cfg file. There, you can disable unwanted patches.

Q: Is there a server version of this?
A: Not yet. The server uses very different mappings and I guess (even though, I have not tested this so far) that it is simply incompatible for now. Also, targeting server mappings requires changes in NilGradle - which would need to be done first.

Q: Are there any plans for 1.4.7/1.5.2/[any other version]?
A: If enough people are interested in this: yes, of course!
