So we all know the early models of Locked n Loaded were actually Dragon Guns, but they took the graphics/program/sound roms off and made them into Locked n Loaded. The good news is they can be easily converted back since a lot of the roms from Dragon gun are still on the board. You need to replace the graphics, sound, and program roms. This will require soldering/desoldering. All of the PALs are the same/equivalent even if they say different numbers.
Front of the board:
You need to take the light gun board off.
On the back board:
Pin 18 and 19 of 26M needs to be reattached and put back into the socket.
Pin 28 on CN1 needs to be reattached to the trace.
Fix on mine: The CG wasn't appearing (IE the boss fights where the backgrounds are CG), it wasn't getting the FREQ from the KD82750PB to the KD82750DB. A 74f245 providing it to the KD82750DB was bad.
Another question is why would I do this? Well there are very few dragon guns left out there and Locked N Loaded has a dedicated version of the board, so might as well convert these back.
