As anyone outside of the hackmii team tried to use MINI already?
The ARM code is there, but there is nothing for the powerpc side. Which is kind of a shame.
(http://hackmii.com/2009/05/mini-source-code/ - "Source code for the PowerPC part is not included yet but we will add an example PowerPC project during the next few days." never happend)
I don't own an USBGekko. So debugging mini would be a bit hard for me, I have experience with micro-controllers without much output. So if I can get powerpc code to boot and just poke the video hardware in displaying something I would be ready to do more.
Right now as I see it, the bootmii boot2 starts the /bootmii/armboot.bin file, which loads the /bootmii/ppcboot.elf file. As elf files contain a start address and everything I don't think it would be that hard to get something to run. So by grabbing some files from libogc and remove everything that communicates with the IOS I think you could get a long way.
But instead of trying to reinvent the wheel I'm wondering if anyone has done something already.
