Trying to make it work with Regular Show: Mordecai & Rigby in 8-Bit Land

[CTPache]

Hi, I know this is an old repository, but I've seen the author is active in other similar proyects, so may as well ask.
I've been trying to use this tool to import/export images from RS:MR8L, but it seems like the format is diffent (either newer or older, first 8 bytes are 6A 0E B4 39 01 00 00 00), so it doesn't work. I'll attach a few samples if someone wants to try. I could do it myself but I'm not very good at image RE.
