: I have not put a Dreamcast in my cabinet... however, try checking out www.spies.com/arcade Then click on the manuals link, on that site, they have the Hantarex MTC 9000 manual in pdf form. With schematics and troubleshooting. Voltage drops can be hell in a handbasket dealing with modifications of these types. Ohm's Law is evident all over. However for you... it could be something simple as the converter construction itself. You've narrowed it down to the voltage problems you say, so I'm assuming you have zero vert/horz sync problems to make it do that. Few options that I can think of.... Rebuild your converter..., perhaps shorten the lines, check syncs... reread voltage signals. If there is no datta on PC2Jamma.... hopefully someone here can help... although its 90% dependent on hardware (monitor and converter). the Hantarex are some of the top of the line monitors on the marker... and should be set to handle it. Make sure your monitor has no technical faults (check the manual pdf if you have one for troubleshooting). Check their website. If you are experienced at electrical engineering... op amps to boost the signal/voltage can do wonders if built safely. From what you are explaining, its hard to diagnose... just test your hardware, schematics, voltage requirements, and troubleshoot it step by step. Sorry I can't help more.... thought I might since I own that monitor myself, but I don't have the consoles in it.. I just have a PC(mame), and Jamma setup. BTW... France use PAL? or NTSC.
Hi , thanks for your response , i'll try to increase voltage with op RGB amp i hope it works !! the hantarex cannot accept lower RGB voltage like PSX,DC,etc wich is 0.7 Vpp
In france the video systeme is PAL !
With my PC without video converter (PC2Jamma) and Mame , the hantarex work fine , PC-Video-Out 1.25 Vpp
Best regards,
