Description
Allows you to use your Nintendo classic pre-JAMMA game, in a JAMMA cabinet or a super gun device.
Nintendo made a huge name for itself in the arcades in the early 1980s. Most of Nintendo games produced between 1980 and 1984, before the PlayChoice and VS system boards were released, used the same pinout. This includes some high profile games such as Mario Bros, the three Donkey Kong games and Popeye.
The popularity of these games created a large market for bootleggers. While the bootleg hardware is almost identical, there are some small changes. The video and sound output signals are not compatible and the pinout itself is slightly different. The original Nintendo pcbs output inverted video signals and require an external sound amplifier, while bootlegs output normal video signals and have an on-board sound amp.
This Nintendo to JAMMA adapter supports both standard and inverted video, and amplified or non-amplified sound. The low cost, high speed video inverter and sound amplifier can be disabled on the adapter making it compatible with both original and bootleg boards via a couple of jumpers. The signal DC offset for each color (Red, Green and Blue) can also be adjusted to display properly on a standard monitor. The video inverter is a simple linear design for the best possible picture at a low cost.
