That's pretty freaky, have you checked to make sure all the solder joints for the header pins are good?

[viletim]

It goes nutty.

It looks like a problem in the analog section of the NESRGB. If you have a multimeter handy, you could have a go at fixing it or I can send you a replacement board. Either way please send me an email and I'll sort it out.

Does that mean... YOU HAVE BOARDS LEFT?

Ever since I found out about this mod, I wanted to say thank you to anyone that is involved with it, finally we have an amazing board that is easy and doesn't require ripping out old Nintendo Arcade PPU's. I can't wait to get both my AV Famicom and NES modified for this. And I must say I've been drooling over the pictures posted of circuit boards and comparison shots, I'm such a geek

Makes me wonder if the NES is the only system that can be done like this, it would be great to see something like this on an Atari if it were at all possible

So I was able to score one of Viletim's NES rgb boards. It showed up probably around a month ago and I finally got around to installing it. It will output a picture but it is just some crazy stuff. I made two videos to show what is happening. First is where I have it hooked up to output component video:

I can't see your setup but you can't hook up rgb format directly to component format.
You need a converter of some sort between the two.

[Slymick]

To be honest, from Moosmann's photos, it looks like the palette is being changed alternately between scanlines, causing some sort of dithering effect. If it's off-by-one, it would start flickering similar to composite video crosstalk. The photos don't really look like composite at all (the picture is way too sharp), and I can't really see a logical explanation for it.

A quick check with a debugging emulator shows the palette in Duck Maze is only written to when the whole screen changes. Maybe you are on to something though... The NESRGB will simply ignore palette writes during rendering. I'm not completely sure if the ordinary PPU behaviour is the same. I'll have to spend some more time with the debugger to find out...

markfrizb,

Ok, I'll change the adapters. Can you (or anyone) confirm that if the new adapter moved the NESRGB board 10mm closer to the front of the console that it will still fit into the NES 2 and AV Famicom ?

Tim are you still after a top loader for testing / measurements ? I've got one you can borrow and I'm regularly in the Sydney area.

Yeah, I am using Ace's circuit off the Sega 16 forum.

In case any one wants to know, you can make a converter to use snes controllers on NES's.
I bought a snes to USB converter off ebay and stripped out the USB stuff and wired the NES wires as shown on the case. A direct 1 to 1 wiring. I grew up playing the snes first so those controls are more comfortable to me than the NES.

Just thought I'd share my mod.

How funny, I just made a couple of such converters yesterday. However, I took a different approach with mine:

And I took and even different approach to mine:



I added Famicom to NES capability using the DB15 Famicom game port pinout.

I added Famicom to NES capability using the DB15 Famicom game port pinout.

Will those work with Famicom accessories, as well as controllers? I'm curious if they'll work with the 3D glasses adapter and the keyboard.

I've tested it with the BPS Max, and configured for player 1 operation. Adding a switch for data and clock would allow for player 1/2 switching.

EDIT:

Upon searching for pinouts for the Famicom 3D glasses and keyboard I discovered that both use pins that are not connected to either NES controller port. The 3D glasses use pins 1, 11, and 15, of which pin 11 is not mapped to either controller port. The keyboard uses pins 1, 4, 5, 6, 7, 10, 11, 12, 13, and 15, of which pins 6, 10, and 11 are not mapped to either controller port. The keyboard is interesting in that it uses both player 1 and 2 connections and D3/4 (minus player 2 clock)!

I don't know why you WOULDN'T want to use the NES controller... I need to get around to making my NES-to-SNES adapter - DKC should play nicely.

Dude, that's pretty sick. He should tweak the code on the receiver, change the layout a bit and do discrete direction/button signals out so you can mate that thing with Toodles' MC Cthulhu and have one universal receiver for all your old consoles. One controller to rule them all!

Had a spare few hours today so decided to attempt the mod on my NTSC Front Loader NES, I will just be using the supplied min-din socket for a scart connection.

I have connected up the R,G,B, V (for sync) and GND, and then +5v and GND for the voltage regulator.....



But have noticed when i connect the nes up to my LCD TV (via scart) im not getting a display at all. I have not shorted any of the Jumpers on the NESRGB board (as i dont think i need to as its an NTSC system). Is something wired up incorrectly in the above picture?

One of the jumpers has to be shorted, J5 I think.

Ah, JP5 is said to need to be shorted for NTSC system for selecting luma trap frequency for encoding composite video, so i do i need to short this JP if im using standard comp sync (solder pad 'V')??.

Also i should add i havent added any capacitors to the RGB lines on the scart plug do i need to do this?

You don't need to as the 220 uF caps are already on the NESRGB.

My 3rd NESRGB vid
NES-101 with multiout, hooked up to an xrgb mini with hdmi out and also to a csy2100 with component out and also with regular svid out.

My 3rd NESRGB vid

I use an XRGB mini and I wired mine up using only the composite sync with no issues. I did not have to use the composite video like that to get mine to work. It worked fine with my own custom scart cable (i use an 8 pin din on mine) on my front loader and on an SNES RGB cable (built by that person in Florida) on Phonedork's AV Famicom. In fact I have yet to run across a device that wont accept sync coming off the CS# pin on the NES RGB kit.

As a side note the CSY2100 family of encoders has some slight issues with this kit. I noticed in Mario 2 on the first level there is a crawling effect on the green structures by the waterfall with the two red logs rolling down it (lower part of the green things). The CSY2100, CVS287, and SDV4 encoders were the only ones that seemed to display this issue. I am not sure if it is present in other games and was visible on every CRT TV I tried it on. It was not present on HDTV's, I am guessing this is due to digital noise reduction. The CSY2100 also does not have this issue on the old RGB mod. I might make a small recording of it later when I am feeling less lazy.

The one you did for me works fine with xrgb-mini. I bought a raw sync cable from retro accessories and did not try composite video sync on mine. On the front display of the mini, you should see the sync light come on if it is getting a signal. If you are using composite video sync, you may have to adjust the sync level in the xrgb mini's menu to get it to show a picture. On my old one you did for me (with the Playchoice PPU) I had to adjust the setting from default of 9 to around 15 to get it to work with composite video sync. Possibly the issue you were having.

Regarding the audio solder pads on the NESRGB, if im going to be have the audio wired to the min-din socket which of the 3 audio solder pads do i need to wire up to the din socket, is it possible to get stereo audio from the NESRGB, and also what about the Famicom extra audio channels how do i go about wiring that up?

Ok i have tried shorting Jumper 5, and now when i connect the system up to my LCD (via scart) it appears to be getting some sort of signal as the channel info disappears from the screen, but the screen is still black (or though it does lighten slightly when i power on the NES). I tried removing the sync wire from composite video output (V) and solder it to composite sync (TTL) (CS#), this still had the same problem but this time the screen became very bright also grey in colour!. An ideas what the problem might be here?, a faulty NESRGB board maybe?

You are not alone in this. I keep a tab open to this thread and the sales site and just refresh it everyday. I just hope Tim's has enough stock in the second batch for all the interest it seems to be generating.

Tim, is there any chance of pre-ordering, or reserving for the second batch? I really don't want to miss out on this run.
