    Weird graphic issue MV1FZ

    Hi all, I have an MV1FZ mobo that had a shortcircuit with the power supply and one of the CX5814P RAM chip burned. I have replaced both CX5814P-35L and tried the mobo again with a supergun and a PC powersupply (both in working state). I have it working but with an unpleasant graphic issue, all...

    AES Checkerboard vs MVS picture

    Hi Xian, I have made the RGB Bypass removing the 4 capacitors and the 6.8k resistors and soldering the 4 cables (R,G,B,S) I have soldered only the cables not soldering any 75ohm resistor to the RGB cables. The resulting image is crystal clear BUT has some type of wave in the image. I have...

    AES Checkerboard vs MVS picture

    Ok, I suppose it's not the ferrite beads cause composite is crystal clear (tell me if it's not related) so i'll make the full rgb bypass. I thought that cutting the traces to solve the vertical lines problem was enough. Thanks Xian! Enviado desde mi Nexus S usando Tapatalk

    Power supply to consolize a Neogeo MV2F

    Well, according to Jamma-Nation and his guide to consolize an MV2F I'm planning to do the +5V only mod: http://jamma-nation-x.com/jammax/cmvs2slot.html Reading the link you provided is enough with a 3A power supply Thanks!

    Power supply to consolize a Neogeo MV2F

    Hello, I'm preparing to consolize an MV2F Neogeo board and after reading all info I found I have a doubt about power supply. It seems that for one slot boards with +5V 3A is enough but with 2 slots... Which one should I get a +5V 3A or a +5V 4A? Which one should work best? Thanks in advance.
