the picture looks so nice :) much better than my old svideo board.
i also got my super nova working with the neobitz board very nice:)

below is what i did.
i dont under stand why i have to tie the normal video sync with the y of the component out(i tried to use small circuit to filter the sync signal but that did not help) it is needed to get the genesis to display the colors right
if i dont the blacks and other colors will have a washed out neon look to them.
i needed the resistors in the rgb input side to keep the colors from flooding out details they are normaly way too intence.

any one have a clue to the science behide the color and black problem?
i dont even know why the cap is needed but i was told to give it a try. it helped sync in the picture.

the picture looks nice but it looks way better in person some reason
the digi cam makes the white look a little on the yellow side

Does this work on any model of Genesis?

Your Genny 2 with the KA2195D should work fine with the NeoBitz. But the price is signficantly more than you buying another Genny with a 1145 or 1645 in it, sending it back and forth for modding, and paying for the mod.

i have tested it on the model one genesis, 1st model sega cd, cdx, 32x, power base converter, tototek master system adapter(like the power base), and nomad.

only the nomad seems to have some problem with it .
the video on the nomad will go out of sync and there is some diagonal noise that moves through the picture on the tv side. the rest are perfect.

there may be a problem on other tvs.... i will have to test it on my old wega.
the svideo out and composite video will not work.
i do get perfect video from the component out.

True, maybe I should just try and purchase a Genny that you have modded already? Do you have one of those?

ALso, the picture looks totally awesome in RGB.

Check the "WHITE BALANCE" option on your camera !!!

D-lite have you moded the genesis first model(mega drive or altredbeast model)with component video?.If so.Is the difference worth paying for?

I've done the S-Video to genesis, but haven't tried one of Jeff's excellent NeoBitz boards yet on a genny.

If that picture is any indication...whoah! S-Video is nice, but that component looks *pure* for lack of a better description. :eek:

"worth it" is directly connected to your budget. Adding a NeoBitz board to a Genesis mod easily more than doubles the cost of the mod from OSG. If you can DIY it, it's definitely worth it. Or if money is not important. :D

Thanks for the thread!

Trust me, modding the Genny is so worth it! The RF output totally sucks. It's no fun playing with vertical bars every 8 pixels or so. Looks like crap.

the neobitz picture is way more pure than the svideo i mod i was using for all my systems.
i think it is the best you can get if you do not have a hd tv.
i have once again upgraded my video for my legacy systems.
i sold my neobitz board and bought a xrgb2 plus.
this works great with my vga port on my tv it also up scans all my video to progressive scan.
the picture now is clear as it can get.
looks as sharp as a emulator on the pc.
no lag a lot of hd tv have a little lag with interlaced video.
some thing to do with the way they up scan it to display the picture.

I've not tried the NeoBitz on a Genny, but I know how much a jump the S-Video alone is. I've found that the standard S-Video upgrade is very very nice.

Now on a Turbo Duo, I've played around with the NeoBitz and gotten it to work quite nicely. I'll have to look at what I ended up finally using, but I had to amp the RGB with a KA2195D (or CXA1145 or CXA1645) first and I believe I had to amp the sync too. Again, I'd have to check. The Genesis has much higher RGB output than a Turbo, so amplifying it shouldn't be necessary.
