I just got a "rebuilt" 6 slot board with UNI BIOS. The sound works better on some games (left speaker was very quiet on 4 slot w/Bomberman), and the graphics are better too (brighter colors, and no more horizontal banding parallel with vertical character movement in Blue's Journey).
Is this due to a better quality manufacturing? Newer techology? The UNI BIOS? Better harness contact? Cleaner slots?
