Looks fine. Did you try reseating the ROMS on the multi and check they’re in the right position? What are your DIP switches set to on the multi and motherboard?
 
without OLED I have black screen after boot so when I move multi dip switch I have this:

Might be even wise to remove all the EPROM chips and reinsert them again for good measure.
 
This is what happened with my kit too... but i thought this happened because i plugged the multi pcb backwards ! In any rate, i’m enjoy with this beauty multi these days ! Check carefully if the rom 1 (keeps 8 games in it) was properly writed also !

this is how my Ultimate SEGA System16 B looks like ✌️

Plugging it backwards didn't damage anything on the multi.
However it had taken a knock in a corner and 3 traces were severed. Simply patched them.

Does your donor board use a MCU 87C51?
If so you must pull it.
