Hi guys,
finally finished this hack which allows you to completely drop the MCU and convert any romboard to Moonwalker!

I've used romset mwalk, just use files from this set except for the 2 program ROMs A5/A6 where you must use my patched files:
http://www.filedropper.com/mwnomcuanyromboard_2

I've found several critical mistakes in MAME regarding sprites banking, also it states there are 3 different known romboards but 171-5987 and 837-7525 are the same thing: 837-7525 is what's printed on the part side under the label, 171-5987 is what's printed on the solder side...
So only 2 really exist:
- 171-5874
- 171-5987

1) ROMs types:

A6 -> 27C2001/27C020
A5 -> 27C2001/27C020
B1 -> 27C2001/27C020
B2 -> 27C2001/27C020
B3 -> 27C2001/27C020
B11 -> 27C2001/27C020
A11 -> 27C2001/27C020
B10 -> 27C2001/27C020
A10 -> 27C2001/27C020
B9 -> 27C2001/27C020
A9 -> 27C2001/27C020
B8 -> 27C2001/27C020
A8 -> 27C2001/27C020
A4 -> 27C100/27C1000 - NON JEDEC!
B4 -> 27C2001/27C020
B5 -> 27C2001/27C020
B6 -> 27C2001/27C020

That's 16 * 27C2001/27C020 and 1 * 27C100/27C1000 needed.

2) ROMs positions

Obvious for 5874 romboards, for 5987 use this conversion table:

Left OG position on 5874, right corresponding position on 5987
A6 -> A4
A5 -> A6
B1 -> B1
B2 -> B2
B3 -> B3
B11 -> B10
A11 -> A10
B10 -> B11
A10 -> A11
B9 -> B12
A9 -> A12
B8 -> B13
A8 -> A13
A4 -> B7
B4 -> B6
B5 -> B5
B6 -> B4

3) Jumpers settings

On 5874:
4/6/7/2/9/16/14/11
35/38/33/40/45/41/31/43
19/24/22/27/29/17/26

On 5987:
2/4/5/8/10/11
18/14/16/19
25/21/23/28
29/31/33/35/37/39/41/43
45/47/49/51
66/68/69/71
