Re: N64 component (aka YUV aka YPbPr) output

Sorry for the late update, but I did manage to get the better S-Video cable wired to the cheapo connector and the picture looks great. The problem is that I've been too busy to properly solder and heat-shrink insulate the connections, so it's currently in a rat's nest of hand-twisted wires. The only...

Re: N64 component (aka YUV aka YPbPr) output

Well now I'm not so sure that it's related to the composite signal at all. After putting the tape back on, I still got intermittent checkerboarding. I cut into the insulation at the N64 end of the cable and cut the composite wire, and still get checkerboarding. Now I'm thinking it's more likely due ...

Re: N64 component (aka YUV aka YPbPr) output

Took some pics with and without the electrical tape over the pin. Sorry for the quality; it was the best I could do without a lot of fiddling.

Re: N64 component (aka YUV aka YPbPr) output

After modding an original Xbox composite cable into a component cable, I'm not sure I want to try hacking the console end of A/V cables any more. There's usually a ton of heat-welded plastic around thick RF shielding/grounding metal, which forces you to all but destroy the connector to get at the pi...

Re: N64 component (aka YUV aka YPbPr) output

Update: After reading the reviews on all the sub-$15 cables available on Amazon, and finding serious issues mentioned for all of them, I got an idea. I looked up a pinout for SNES/N64/Gamecube and put a piece of electrical tape over the composite video pin, then plugged it back into the N64 and turn...

Re: N64 component (aka YUV aka YPbPr) output

My N64 is NTSC. And it looks like you're right. Damn. I didn't want to believe it, but it looks like it's a common issue with S-Video: http://preservation.bavc.org/artifactatlas/index.php/Poor_Y/C_Decoding_%28S-Video_crosstalk%29" onclick="window.open(this.href);return false; The problem is that I d...

Re: N64 component (aka YUV aka YPbPr) output

I ended up buying a cable that had inputs for various consoles on one end and S-Video plus composite plus audio outputs on the other end. This made it really easy to compare S-Video to composite video by switching inputs on the LCD TV that I'm using. Unfortunately, however, I almost regret upgrading...

Re: N64 component (aka YUV aka YPbPr) output

I'm a bit hesitant to buy one because the only one listed for $5 or less (price + shipping) has reviews from customers saying they got stuck with a composite-only cable. Maybe I'll pick up this one for a few cents more though: http://www.amazon.com/Universal-AV-S-Video-Cable-GameCube/dp/B000067QIG" ...

N64 component (aka YUV aka YPbPr) output

So a co-worker gave me his N64 stash (which includes 2 USA N64s, so I don't mind modding one), and I finally got around to testing it out a bit on a spare LCD TV. The composite video quality is terrible, and the S-Video versus composite comparison pictures I've seen online don't have me excited abou...

Re: Stereo mod - which method?

It sounded like maybe you were building two amplifier circuits (one for each channel) based on the original NES amplifier circuit design, instead of leaving the original one on the board intact to handle one of the two channels and then building a second for the second channel?

Re: Stereo mod - which method?

I'm surprised you didn't use the already-existing circuit for one of the two channels by removing the mixing resistor.

Re: Stereo mod - which method?

Topic revival LOL. I am just now finishing soldering up my first circuit which is using the whole of the components in the above schematic using the 74HCU04, and am going to try it on my NTSC revision 4 toaster NES. If it works I'll post more. Cheers, Alistair G. Let me know how it goes. I think th...

Re: NES cartridge battery replacement woes

Okay so I'm a TOTAL idiot. I was trying out NES emulators on my new HTPC(*) and I noticed that Crystalis has a hard-to-find save/load menu that I had forgotten about. When testing my real cart previously, I was mistakenly trying to "save" by resting at the inn (that method seemed to actually work ac...

Re: NES cartridge battery replacement woes

IIRC most NES games use 8KB srams for the save ram, so replacing it shouldn't be an issue, though I doubt your save ram has been damaged unless you're really bad at soldering. You'd probably do more damage than good in the process of trying to replace the sram. Any idea what *could* be the problem ...

NES cartridge battery replacement woes

So I pulled Crystalis off the shelf a week or two ago and played it for a couple hours, then saved my game and turned off the NES. When I came back the next day, booted up the game and hit Continue, I found that my save data had been lost :( I did some testing and found that the game retains the sav...
