>>33068255Yeah, trial and error will really help you decipher .spa files, a file type you can only view with a mario kart editor with no way to edit it.
And sure, you might be able to open up a hex editor and change the image itself (because it's there, in hex, you can see the image) but the information that precedes it is undocumented and tricky to edit at best. In fact, all I can figure is there's supposed to be palette in there somewhere (with transparent colors)
but hey, trial and error, right?
