The scaler really is very good, for the boards it supports I would dare say its better then the xRGB Mini.
That however is the break down... FOR THE BOARDS IT SUPPORTS!
It simply refuses to scale/sync some games period, the xRGB Mini has always worked (I'm told it has issues with Taito F3) for me with anything.
This is my list of boards I've personally tested with the Taito and found not working.
- Mortal Kombat 1/2: I suspect all Midway boards on the Y/T Unit have this problem, funkey refreshs to blame.
- Captain America and the Avengers: Sync on this and I suspect other boards from Data East made around the same time.
- Pang/Buster Brothers/Super Pang/Super Buster Brothers: Sync pulse isn't wide enough, only works on a analog CRTs with out a generator.
- Aliens: Only Konami board I've tested that didn't display, TMNT2 needed a Sync cleaner but it works.
Now as for Naomi... Yes the scaler will take the 15khz output from a Naomi and upscale that into 31khz.
But why would you ever do that? Just change the output of the Naomi to 31khz with dip switch #4 on the com-board.
Do you mean to say you have a Naomi Uni cab, that is 31khz only and you want to use 15khz boards with it?
Yup that will also work, just be aware you will have to modify the wire harness that comes with the JAMMA kit.
Derick is correct on the price too btw, with shipping and fees its closer to 450$.
The lead time is insane on this kit, so if they have it in stock and you don't want to wait 6 months... Order it!!!
