Unless you are actually looking for a reason to do some (de)soldering (I probably would, if I could  ) I'd contact porkupan (aka boroda) on this matter.
PS
Very offtopic
I bet Georgian is even more difficult, just an example:

Yes it is re-animated; but I can't get it to run anything from porkupan, or others. It is locked in normal Sony mode -- it is better than when I started; for I can use the sony store now.... But, I'm irritated with it. I would contact porkupan, but I only have one day -- and I doubt I can get a 1 day turn with him speaking Russian.... If I can't work it out by tomorrow, I'll give up until I'm back from vacation -- roughly three weeks... and then I might try porkupan. Your links did help. Thank you.
I deciphered all the chips in my Sony. Wow. Three MCU's, one ARM11 w/ multimedia (400MHz or so) One what looks like a Renesas: R5F21246SNxxxFP R8C microcontroller 32K rom. 8/16 bit processor, and then a third one possibly integrated into the Samsung 2G flash rom. Why sony needed the extra Renesas one has me stumped. My curiosity is getting to me. This thing is seriously overkill in the way it is built -- the ARM processor has all the peripherals built in, but Sony still used external peripheral chips... that makes me wonder why.
Desoldering full chips is impractical in one day, but it looks like I might be able to isolate the flash memory and decode it; there are several test points .. it just depends on how quickly I figure them out tomorrow. A task beyond the typical hacker....
