So I opened up my 120-in-1 and snapped some photos.
The whole thing is just 3 Altera CPLDs, and bunch of Fujitsu Memory (all the same), and a 8 bit microcontroller with flash.
Microcontroller:
ATMEGA8L-8PI Datasheet - ATMEL Corporation - 8-bit AVR with 8K Bytes In-System Programmable Flash
http://www.alldatasheet.com/datasheet-pdf/pdf/80252/ATMEL/ATMEGA8L-8PI.html
CPLDs:
Altera EPM3256ATC144-10
http://www.arrow.com/item/detail/altera/epm3256atc144-10
Memory:
Fujitsu MSP55LV100S
There is a lot of people selling these, but I cannot find a datasheet anywhere.
My thoughts are that the menu is all controlled bt the microcontroller and if we can read the flash in it and hack it we can at the very least edit the menu.
If you look at the photos there are places to add more memory that are not used. I bet it would be possible to add more memory and more games!

Mysterious Cable 1 and 2 header!?!
