August 10th, 2015 update: JGP AES 2.0 now plays on all 17 known AES system variants, including the previously incompatible 3-6 motherboard. 15/20 original release (version 1.0) were sold, so the remaining 5/20 pieces were revised and converted to this new 2.0 version. No additional pieces were created and the serial numbers remaining can be chosen from below. The v2 inserts now use gold foil rather than silver & "Version 2.0" was added to both the insert and cartridge sticker. The sticker uses a newer process and is now laminated and die cut. The insert is also cut by machine now. These five 2.0 copies were fully tested on the multiple systems, are perfect new, and sealed.
Due to numerous unsolved complications, never before has anyone been able to produce Jockey Grandprix on home cartridge format. Involving two years of engineering development, JGP is easily the most complex and challenging MVS to AES conversion to date. This professional (but unofficial) production will be released in snap case format, complete with insert, full color manual, cartridge sticker with gold warning label, & epilepsy warning card. The NeoStore had urged the manufacturer not to rush the production and to take whatever time and measures were necessary to produce the exceptional quality that the purchase price commands.
JGP MVS version:
- With a converter you must have a unibios to run the game.
- The game will only work in MVS mode on converters, using home
mode will cause the game to get stuck at a service menu.
- The game requires a unibios cheat code for credits or the use
of external hardware plugged into the cart.
- The cart uses a custom program board with SRAM making it
impossible to convert using normal methods. As stated
above, even if you did convert it, you will still be limited by
JGP AES version:
- Uses all original ROMs from the MVS cartridge.
- The game
runs off two high quality custom made PCB's that are virtually
impossible to replicate.
- The game will run on all AES decks with stock bios in home
mode as well as debug and unibios chips.
- Pressing SELECT will add a credit, no need for a unibios or
- Each game will be uniquely numbered by a tamperproof method on the insert, manual, and cartridge sticker.
- Tested to run on all AES decks with all known bios versions.
- Limited to
this 20 pieces worldwide with the assurance of no future
Condition: New, mint, & unplayed. Factory sealed with round Neo-Geo sticker.

Note from DG Enterprises Limited:
"JGP was fully tested on 17 AES systems from first gen,
3-3/3-4/3-5/3-6 with many systems tested as both 5v and 9v+ versions. While the
game was being tested, it was noticed that a single 3-6 system wouldn't run the
game. The game would boot to a black screen with no error and full unibios
access. That 3-6 motherboard was sent here for testing to figure out the issue,
and to look for a solution. This version of the 3-6 motherboard looks the same
as any other 3-6 but has a few parts with slightly different part numbers. From
my test, it seems this motherboard was changed slightly to fully work with the
newer parts. In doing so there is now a conflict between parts on the
motherboard and the SRAM found on JGP's program board. My test show that a new
unmodded MVS JGP using any converter will also boot to a black screen on this
3-6 system. Over the past week I've tried to correct the issue in the games
program rom, however the problem can't be corrected with software."
