I'm curious if anyone has an idea on some graphics issues I'm seeing. Games load, most sprites have full shapes, but don't display in anything but flat colors - different colors per sprite (or background).

I installed a multiboard, with install/troubleshooting steps including:
Unfortunately I don't have other hardware to test with, though I could put the old ROMs back in after using the multi to write a new key. The B-board was last known to be working (supposedly), but the battery was dead when I got to it and applied the multiboard.
I've got a bad feeling I need to replace some chips on the A board somewhere, does anyone have any ideas or things to try?

I installed a multiboard, with install/troubleshooting steps including:
- Lifting the G PAL pin and wiring it to J17
- Wiring up key writing pins
- Verified board jumpers (board was MvC, valid jumpers out of the box)
- Checked continuity between graphics ROM pins on the multiboard and the bottom of the sockets (pins appear to be set fine)
- Reformatted SD and reloaded ROMs
- Connected A and B directly (no cases, no 'wiggle room' between the boards)
- Reviewed the board for obvious scratches, no trace issues that I could see
- Battery is removed
- Shorted cap near the battery to remove stale key data
