So, as you might all be aware, the lv0ldr and metldr contain perconsole crypto that is handled either by a rom and fuses or by RTL that would make it impossible to retrieve without expending quite a lot of cash on chip analysis (which is money that i didn't have back when i started this project)
So the goal was to find the ellusive rom, decode it properly and get the resulting binary tell us its secrets. Unfortunately, instead of getting the bootrom, we got the microcode rom, which is a rom that translates ppu instructions into more simpler cpu instructions. This was done by decapping and SEM analysis (no other way to retrieve this microcode rom exists) and for the sake of anonymity the people that helped make this come true shall not be mentioned here.
3 files will be shared, they're all txt and they all represent the bits representation of the rom. No images shall be shared for the sake of protecting the person who helped us with this. I believe the majority of the group has given up trying to make sense of a binary that would have, at most, 0x1E00 bytes (to give you an idea of how large the xbox 360 rom is in comparisson it is 32 Kilobytes, or 0x8000 bytes, which makes us believe this is not the right thing)
