new WORKING machine (Lexibook 120-in-1) (#5993)

* new WORKING machine
-------
Lexibook JG7415 120-in-1 [TeamEurope, David Haywood]

(weirdly uses a 256MB rom, full of data, but only 128MB of it is for this game, also didn't give 100% consistent reads, asked Klaus to check if bad bits are in unused areas, could have been intentional)

* remove debug code (nw)

* remove debug code (nw)

* (nw)

* (nw)

* less unstable reset behavior (nw)

* looks like the faulty ROM is intentional, and it was wired up in such a way that the game wouldn't fall on the faulty parts (nw)
