Has anyone outside Datel ever dumped the Mechacon firmware of a retail PS2? It would be quite hilarious to find an exploit that could be used to write to its RAM while it's running. You could make a Free McBoot that let you run imported games directly on an unmodded retail system. =)
I'm sure someone like l_oliveira, SilverBull or sp193 can give more details; but AFAIK this is not possible. The mechacon is a SoC and IIRC can't be dumped (or can, but is encrypted). Here's my assumption: Even if it could be dumped/decrypted, being a SoC means it has its own RAM and I don't think you can write directly to it. I think this was discussed a couple of times, but my memory is not good. Anyway, you may want to ignore my post and wait for someone with more technical details to provide a right answer ^_^
Yes, it has its own RAM. That's why it'd need to be an exploit. If there is a bug in the firmware handling a command from the R3000, it could let us overwrite arbitrary memory locations inside the controller's RAM. In order to do that, though, we'd need to dump its firmware.
Sorry to resurrect a long-dead thread, but I was wondering if there has ever been any progress on this?
I doubt so. Otherwise, it would have been pretty widely-known. It seems to be similar to the CXP974F064. But because these devices are very obscure, there is not much information to go about.
