| JAMMA compatible MAME cabinet : Feedback please |

Thanks for the input CheffoJeffo. Maybe I was a bit unclear in my first post. I'm actually building a Cabinet from scratch - primarily to run MAME, but I also want to add the JAMMA compatibility, hence why I am running a TV - and note that arcade monitors are hard to come by second hand in OZ, otherwise I would have gone the arcade monitor route. And as for sound, I plan on using an amplified sound card, that way it should be fine to run sound for both the MAME machine and the game PCB's. |

I goofed (in my head at least) thinking that TV had horizontal scan rate of 30 kHz instead of 15.75 k Hz .. ma70ltd: I get it now ... will be intrigued to see how it works out ... wonder what kinds of resolution issues you'll run into. Keep us updated. Cheers. |

I should be fine running the video feed from the J-PAC/JAMMA harness and running it through the RGB-> PAL video convertor - as per Jeffo's bit of advice I guess in the end it comes down to : I either have to buy an arcade VGA card or just build an S-Video double adapter. I think the latter will be cheaper for me. Thanks Jeffo, Ray and Bob for your feedback :) Will keep you all posted |
