aristmk4.c:
* Cashcade workaround for topgear [Frasher]
* Improved a few memory handlers [Palindrome]
out of whatsnew: the original patch contained more changes so probably someone might want to contact Palindrome & c. about these.
1. the way ticket output was handled has been rejected (MAME should not print out files like they did)
2. they changed a rom in autmoon and another PROM: since I'm not sure if the roms are available and the commit message did not mention them at all, I cannot judge if the change is fine
3. the way they implemented Robot Test is debatable, but I know nothing about the hardware, so someone should review that part
4. if they want to remap Jackpot inputs, they should choose a key not already in use ('I' is taken as well) and possibly use the common IPT_GAMBLE we have
