I'm working on carset manager 1.0 which has a totally different structure, and a lot more capabilities. It will be compatible with Gp4Tweaker, and also with CamEditor 6.4 files.
Maybe i'll release another version first with CamEditor 6.4 file support first, because that shouldn't take much time. I looked at the file format and it shouldn't be a problem.
1.0 should have a lot of new features and maybe it will be the last version that i'll make.
Don't worry... there's going to be something else which should replace it, and which is a lot better.
I'd rather have a bottle in front of me than a frontal lobotomy
