I might look for an original DD board if my wire connections are compatible. Would all I need to do is plug my existing wire harness to the board’s edge connector?
It never hurts to double-check the PCB and harness pinouts when swapping boards, but reverting back to an original Double Dragon board
should be plug-and-play.
The edge connector on a Double Dragon board uses the
very common
JAMMA wiring standard.
https://www.arcade-museum.com/game_detail.php?game_id=7619The harness is probably original and the bootleg is probably a JAMMA board.
If you want to double-check that the harness hasn't been altered, here's a JAMMA pinout.
Is there any websites that sell these other than eBay?
If "these" = wire harnesses:You almost certainly won't need to replace the harness, but there are many vendors that sell JAMMA harnesses.
Watch out for the "CHAMMA" (Chinese JAMMA) harness used by many of the X-in-1 multi-game boards.
- The CHAMMA harness changes some of the unused pins and grounds (pins 25-27+c-e) into button 4-6 inputs for P1 and P2 instead of using a separate "kick" harness for games that need those inputs.
- IIRC when pins 27 and e are connected to ground (JAMMA standard), a CHAMMA PCB won't boot properly because it thinks those buttons are always pressed.
If "these" = original Double Dragon boards:If you can repair the audio issue so the bootleg is working fine, it may not be worth the effort and expense to revert to original boards.
You can put "want to buy" (WTB) posts in the
Buy/Sell/Trade sub-forum and on KLOV like Gilrock advised.
There are also vendors that sell used PCBs.
