I hate to resurrect a dead thread, but this is an issue I'm still having a problem with. I've found some great potential stages to use for my sprite comic covers, only to find them unusable due to only being able to see them in red, blue, or green only. Is there a way to reverse this process using either Fighter Factory or an image-editing program like GIMP? Everything I've found via Google is about how to do the RGB method in the first place, not how to reverse it.
Thanks!
