You erm are aware that Sega Arcade machines that run Model 3 / Naomi boards are running Medium Res monitors that couldn't be used with JAMMA boards?

[steve_dynamic]

well i wasn't gonna run games like defender or Pacman.. rather the newer games that run on things like CPS3 and Neo Geo...

Heh, but you are aware that CPS2/3 and MVS are still er JAMMA and still er run at Low Res. Not that Pacman and Defender were JAMMA anyway...

What game was running in the machine?

[steve_dynamic]

Virtua Striker 1 is running at the moment cause for some reason, its a Model 2 board inside... It should be okay since Sega has a Jamma cable from the Model 2/3 board so it can be used on Jamma machines.

I just need someone who is good with electrics and electronics to make me a cable.

The only point your missing is the fact that the monitor is a medium resolution monitor (it's between Hi Res (VGA) 31.5Khz and Lo Res (Standard SCART TV) 15Khz). The monitor could be a dual resolution monitor (it will autoswitch or will require a jumper moved), but I know that not all Sega Model 2 arcades did have a dual frequency monitor. If not then you would have to replace the entire monitor chassis for it to run proper JAMMA boards.

Sadly I am in Finland at the moment, otherwise I would have popped in to help you out (and probably helped convert it and make those PS to JAMMA converter too.

Me & Saur checked the manual and the monitor can take Standard and Medium Resolution.

Hmm. Are you on holiday? When will you be back? Cause I really need to get this Jamma Harness done. Also those PS pad converters.

Will PM you tomorrow.
