    Some weeks ago i got hold of a 256M Ezfa cart. The problem was that it came as is, some games on it, no cable or anything. So i searched all over the internet for cables and couldn't find anything. I tried different solutions but with no luck.
    So I decided to do my own programming hardware, but first i needed to find how to write and control the damn thing, since it's not a standard procedure. Here is a bit of reverse engineering applied to the cart. I couldn't find anything about this on the internet so if anyone knows someone else who did this and posted please PM me.

    Two documents: One is with findings as it went, and the other one tries to be a more polished one (but a bit scarce on the details), feel free to view them both.

    I also made some custom USB programming hardware using an ATmega164PA, but the software is a bit... well unfinished and i must work some more on it. Will release full package with schematics, PCB and software once i think it's at least decent.

    Excuse my english, not a native speaker.
