Another board from my friend ‘mastercello’ and another quick fix.

We have on the bench a Raiden DX (Seibu Kaihatsu) PCB in  good shape:

Raiden DX_PCB

Board booted but colors were wrong and sprites colored blocks:


This Seibu hardware doesn’t use many components since most of logic has been condensed in some custom ASICs which have mostly graphics functions so I focused on them.Like I usually did I probed the tightness of each pin with a small needle and found some lifted pins of the one stamped  ‘SEI252 SB05-106’ (QFP208 package).


A simple reflow did the trick and fixed graphics completely.
