I'm rather confused, now I've made a fair few bootskins and to actually use them I normally get the main bitmap, the progress bar bitmap and the .ini file, zip them then change the extension to .bootskin and it's always worked, but on my latest one it wont, says there was an error and it might be due to a corrupt file or something. Now just in case I did something wrong I did the same thing with another bootskin, one that I knew had worked, and the same problem again.
Any ideas folks?
