The #SEGA #MultiMega repair log of SN: Y001983. This poor unit has been with me for quite some time due to a lack of references or working systems to compare against until this year.
Also it has been previously professionally repaired by another party.

So, it turns on and play games; where's the issue?
Operation is somewhat haphazard at best. We're missing some audio effects, 6 button controllers do not work in 2P and are erratic for 1P, noise during operation in audio & video and CD games work intermittently after ten minutes

So it had been "recapped" along with having the SEGA 315-5660 ASIC replaced due to corrosion. The latter is no small feat to be taken likely for such a fragile multi-layer board. Sadly the quality of the rework is not up to scratch nor are the trace repairs. Also, missing a pin.
