So it looks like the MB8421s were both replaced or reflowed as there was a ton of flux around them. I cleaned things up and fixed some bad soldering and now the board just boots to a shredded mess of colors...Actually, ignore my previous post.
Palette RAM will most likely be the 3x SRAM (labelled 2088-35 on the board - one per colour)
MB8421 is work RAM
So I by chance ordered another motherboard and have the same shifted top right bottom pixel issue (it's like 3 pixels at most). Piggybacked the ram on my original board and no change.Hey, that will be fine, same type different brand
The board actually has 2088-35 silkscreened on it!
in some days we have them in stock againGah! I was about to order one, and now saveyourgames.it is out of stock. Any idea when a new batch of multis will be available?

Did you ever resolve this? I just noticed my F3 throws a color ram error on Rayforce. Every other game seems to load just fine.I also get a color ram error when booting Gunlock, but this happened on my Rayforce conversion cart as well.
Mine arrived the other day (just going nuts with multis lately, not much else to spend money on in 2020!) and I'm extremely happy with it, now I can play the best game on this hardware:
Neither, it is a normal sticks and buttons game (check the input test in the service menu):Riding fight uses rotary joystick doesn't it ? Or is it just an Arkanoid style dial ?
