Hi Heihachi_73,
Yep, those are the ones I have. In the manuals for the US machines (I also have a US MKVI manual but no schematic), it does mention that the main board may have the DES chip although, it is not used by any US games.
I have a number of dumps for MKV and MKVI games that are not listed against the mame .c files that are dumps that I had personally made.
I'll have to see if I can mod the aristmk5.c files to add them but it will be no good without the 2Khz timer not working at least.
I'm going to have agood look at Arculator now.
Thanks again for the info. If you need any help, let me know. My current studies are in Software Development.
Cheers,
Col.
P.S. I did manage to get a MKVI main board working on a MKV machine provided that the MKVI game did not need a touch screen. All that was needed was a jumper change in the backplane.
Later.
