Thank you. I was finally able to install it, I think my setup is to blame for all the issues. I think I wasn't able to open the .mbin because I downloaded it on Linux before moving it to the emulator, and it missed some information in the process. Downloaded it inside the emulator using iCab, and after several tries (probably because networking on my emulator doesn't work properly) was able to open it on StuffIt 5 and decompress the .gz during the installation.
