The thing is, they used to work fine on all of my consoles, including that AtGames "thing" (I have never owned a model 1 MD/Genesis) - it's only during the last few years where they refused to work at all.

Columns: SEGA MPR-13286-T 5M62-15-D966 9227EAI JAPAN
APTG: SEGA MPR-12645F 834200A 0G6 BK 9104 Z02

Consoles:
PC BD MD2 VA1 PAL (PCB: 171-6534A-20, stamped 09C34; 68HC000 dated 9339)
PC BD MD2 VA1.8 PAL (PCB: 171-6534B-21, date stamped 17 NOV 1995; 68HC000 dated 9535)
PC BD MD2 VA0 PAL (PCB: 171-6349A-21, date stamped 26 AUG 1993; 68HC000 dated 9329)
PC BD MD2 VA1 PAL (PCB: 171-6534A-21, stamped 17K13; 68HC000 dated 9336)

The last console is the faulty one (blank/solid screen after showing "PRODUCED BY OR UNDER LICENSE FROM SEGA ENTERPRISES LTD.") - the two "bad" games fail to show the license screen at all on any console.
