The Pro has two 4455LLYBQ1 chips for the game flash/psram... I knew that already - Dr.neo mentioned that in a PM sometime back and I forgot about it.
It uses the ST M36DR432 for the menu flash/save ram.
EDIT: Rather than hijack this thread further, I've started a separate thread for writing the flash on the NeoMyth.
