got a mv-1A for cheap off an auction site.. following sympthoms: Garbled screen, constant resets, ticking noise.. screen has random patterns, sometimes letters etc in the squares too. bios is NOT at fault, all pin connections checked out fine, unibios won't boot either. verified on another...

I have a MV1ACHX here (same size as a MV1FZ, but with different layout and non-socketed bios chip). sound was supposed to be defective, and it is.. I already tried to get sound out of the unamplified/input pins of the amplifier, there's no sound there either. I found soldering near the yamaha...

I've found a load of pinouts that all claim pin 11 carries mono sound on 2-6 slots.. but on both my old 2 slot and now my 4 slot there's no sound on that pin at all. are the pinouts all wrong or am I missing something?

I got a 4 slot here which has a really odd color problem. the green color is missing some shades.. namely the brighter ones. instead, the shades "start over" at dark green. the red line is just there to show where it starts over. which also results in white being normal in the gray shades...

are there voltage regulators or circuits that can get -5V out of +5V? that way the jamenco PSU could work for i.e. midway boards too.

I got a puzzle de pon today which has what looks like an original label, no warning sticker.. V1 is a chip with the number 044 (art of fighting), C4+6 (I think) are 057 (World Heroes 2), 1 V and 2 C roms are NEC chips, proms (not eproms), and M1 and P1 are eproms labeled "PB3". any idea what...

Fujitsu MB3516A Had no luck finding a sample order form, and of course don't plan on buying quantities of 1000s. I believe this is the RGB encoder used in the Jrok.. I'd like to give it a go and will supply diagrams if it works.. that way people could build their own jrok. any place that sells...

I got a selfbuilt RGB encoder here, based off the AD 724. the problem is that I have horizontal, thick lines running through the pic, mostly noticable on black background, totally invisible on white. the s-video picture is VERY good despite the lines, the AV pic good, but gets distorted by the...

I got a 2-slot today that has a z80 error. I replaced the Z80 with a Z80B. same error. I figured what the heck, and installed an unibios, same error.. then I installed the asian bios used in mv-1B/C units, which have the z80 integrated into another chip.. and it works. not only that, but I get...

no, I know how to get into the menu :p when navigating, the controls seem messed up in the menu.. i.e. buttons will move up/down, directions will confirm/abort etc.. is that normal? the controllers work flawless in-game, and the joystick test also displays them as normal.. it's been ages...

I received a MS3 today "with gfx bugs". Unfortunately they aren't just bugs, but 90% non-existant. The cart is 100% original, the contacts as clean as they can be, the MVS unit perfectly fine too. <img src="http://pirate.sparkhost.com/~arakon/MS3-1.jpg" alt=" - " /> <a...
