You gave some instruction, but I still need some help.
First how do I create a alternative ISO. I looked at the meta link files for other alternative ISOs. There appears to be a number hashes that need to be created. Is there software that can generate this file based off a current iso of mint linux?
Second you told me to modify items in the wubi/src directory. I do not find the directories, so I presume that I need the source of wubi, modify those files and recompile. If this is the case then where can I find the source code? Second what is needed to compile the source code on linux?
