About the error messages...
I'm going to fix that in the future, but that's the most boring part to build, and not most important (for now). If you are having errors and you don't have a clue what is wrong, just send the carset manager.log file and i will take a look at it.
It doesn't support loading pictures yet, but i will add that in the next version.
And about the unwadded wad... Do you mean an empty wad file where the program adds all files that are in the carset?
If that's what you mean.. yes i've been thinking about that too, cause i think it'll be cool to have an option to add single cars in a carset instead of using complete wad files. But first i'm going to focus on other things, because the programs' main perpose isn't edit gp4. Its more like a startup manager, although it modifies some stuff (but restores everything afterwards). Maybe the program will evolve to an true editor, but i'll have to catch up, because i started a little late with this app
But even if that is what you mean.. can you explain me how it would make things easier to test things? The more clear it is to me, the sooner you'll have your version which does everything you want
Ok... now i'll get back to work on the program because i recieved a lot of requests
