I have an Xeye that seems to work just fine except the video output is completely messed up. You can't make out anything on the screen. It's just a bunch of colors and sprites. The genesis and sega cd parts play games fine as far as I can tell. At least I can hear them all boot up. Any ideas? I have several genesis model 2's as parts systems so if I need to replace a part I'm sure I have them.
What kind of video encoder does the X'Eye have? Maybe take a logic probe to the pins of the encoder and see what's going on. I've had to replace the CXA1145 in a Model 1 Genesis before (though it might have died due to the owner's previous mods).
Seconded Guntz's suggestion. If you need an encoder I have spares for most everything genesis related.
Hey thanks for the reply.
I have just replaced the encoder. Still the same symptoms.
Oh and it uses a cxa1145
Capacitor issue?
What output are you using?
Ive tried both outputs and i have caps on order. I will try to get a pic posted tomorrow after work. Ive never seen an issue like this in any genesis.
Can you tell if the graphic glitches are digital? Or are they like analog noise? If the former, there's a possibility the VRAM is bad. I don't know the specifics of the X'Eye, but it should have at least one RAM chip for video data on the Genesis side of the combo system. I guess just look for a RAM chip with most of it's traces connected to the VDP.
Yeah, I was gonna suggest the RAM or the VDP as possible points of failure if the graphics are corrupt. You younggins are one step ahead of me!Quote:

Dangevin is a member of NintendoAge. I don't think he's the same person as retrogamer343...
No it's not me and I think my problem is worse. Here are some pics:

It slightly reduced Master System compatibility. Reset into SMS mode while running was broken (used by flash carts).Quote:

None of those pictures work.
They all work on my end.
That's... interesting. It looks like faulty RAM.
What were all the chips you replaced? Looks like there's other RAM chips on that board. The best solution would be to use a logic probe to check the RAM chips and see if any of them act funny. Just reference a verified working RAM chip, either on that X'Eye or on another Genesis. Otherwise, you might end up replacing all the RAM chips and still get nowhere.
Really? Who was the previous owner? I don't recall the 1145 being a picky encoder.Quote:

Did this X'Eye ever get back in working order? I know the X'Eye aren't easy to come by, I've never seen one in person. Oh one more thing can the X'Eye run the 32X add on?
No I'm still working in this. I plan to try to recap it tomorrow and see what happens. I do believe that it will work with the 32x.
^^
X32?
The Sega 32X works fine on an X'Eye. The only issue would be if you wanted to change discs with the 32X attached.

lum i would still like to find a fix for the master system problem on the x eye. theres got to be a trace or two that are not connected.
I have no idea. It affects only roms anyway.
