Playstation 2 or Xbox to JAMMA adaptor

[frothmeister]

Hi there, I am looking to purchase an adaptor to enable me to play Playstation 2 games on my 6 button JAMMA cabinet. Failing this I would like the equivalent for an Xbox.
I already have a Playstation 1 MGCD board that works well but have not been able to find the eqivalent for a PS2.
It is also pretty vital that it will be compatible with a UK PAL Playstation 2 console which has been fitted with a mod chip and therefore plays ALL UK,US or Japanese games. I have loads of arcade collections such as Capcom Generations,Namco Museums etc etc for the Playstation 1 from various regions that must also be compatible.
I have no interest in coining up the games properly as the MGCD does in credit mode, I only ever use the timed mode on my PS1 version.
Does anyone know where I can buy such a device?
Many thanks, Danny
