Dumping AR firmware?

[ExCyber]

Anyone got any idea how to dump the firmware of an AR via commslink? I tried using action.exe to dump the various cart address spaces (at both cached and uncached addresses), but I'm not getting anything...

Isn't the firmware mapped to a portion of the BIOS memory?

Not that I know of... it does copy at least part of itself to RAM, so depending on what it copies I might be able to use that to accomplish what I want.

Just curiousity.. what is that that you want to do? Sounds VERY interesting...

I want to write a CD-based flash util for AR carts... I don't think I'll actually need to be able to dump the firmware though; I wanted to dump it so that I could do a test write to some nonessential region before overwriting the actual firmware, but I should be able to just alter a cheat code region to do that...
