Re: RGB Mod streaming question

Capturing RGB now is easier than it ever has been. Two reasonably priced solutions are the Datapath E1/E1s cards, which on ebay can be purchased used for around $100, and the OSSC, which is a scaler that runs around $160 but is designed to make RGB very friendly to HDMI devices, whether they are cap...

Re: Famicom AV Mod Situation in 2019

Okay, so you can keep the choke in place and limit the amount of work you have to do. Do you even need to add a tantalum to an AV Famicom? I can't see any jailbars in mine and I have looked hard for them. Do they become more noticeable once the 560pF is removed?

Re: Famicom AV Mod Situation in 2019

A basic question I have is that with the tantalum route, you do not need to lift the PPU Video Output pin to eliminate jailbars? That is a good thing if you do not have to do that. So, if you want to improve the picture quality on an AV Famicom to make it sharper, you should remove the 560pF capacit...

Re: RGB Mod streaming question

The NESRGB mod modifies the original PPU-generated Composite Video signal into an unusable state of black backgrounds and white sprite boxes to get RGB. As lidnariq says, you can enjoy RGB, S-Video or RGB-derived Composite Video using the mod. You can stream the RGB and use the S-Video or Composite ...

Re: New VRC7 patch set

How difficult do you think it would be to adopt Nukey's method for the original YM2413? That chip's patch set has yet to be dumped. It seems like, according to the wiki, that grounding the debug pin on the VRC7 seems to turn some of it's other pins into the bus control lines available on the YM2413....

I know you had already figured it out, but I did post visual proof of the microphone working to haggle the shopkeeper down on original hardware several years ago : https://www.youtube.com/watch?v=aF_TynJ-c6w

Re: I think the VHS side of my VHS/DVD player is defective

Also, make sure the tape advancing mechanism is working properly. The capstans and the pinch rollers should be keeping the tape taut as it travels across the read heads.

Be wary of the ones from China, they may be factory rejects, remarked clones or dead chips.

Re: The state of PowerPak mappers

(Also the Everdrive's USB upload interface is much better for testing mappers.) I also think the Powerpak is the more capable product as it gives you control over A0-A2 and can support the MMC5's vertical split screen. Probably doesn't matter to most people as the MMC5 vertical split screen feature...

Re: Does RF Famicom work with "cable-ready" US TVs?

Japan, like the US, used the standard 300 Ohm twin lead balanced connectors for connecting VHF antennas. However, for 75 Ohm coaxial connections, they did not adopt the screw connector as we did, at least not until later. The connection is the same, the center wire would be wrapped around a screw-ty...

Re: Does RF Famicom work with "cable-ready" US TVs?

I hate the auto-scanning feature. Fortunately my TVs will let me add channels manually without weirdness. So I typically have Channels 2, 3, 4 & 95, 96 added manually. Atari was partial to allowing the user to select between 2 & 3 via RF, Nintendo preferred selecting between 3 & 4. Over the Air and ...

Re: Does RF Famicom work with "cable-ready" US TVs?

It is not particularly surprising that some TVs omit cable-ready channels 95, 96 & 97. The frequencies at which these channels operate, 90MHz to 108MHz, lie in the heart of the very busy FM Radio spectrum, 87.9MHz to 107.9MHz. The conflict between the two band frequencies must make for some crappy p...

Re: Does RF Famicom work with "cable-ready" US TVs?

If your US CRT TV can allow you to select channel 95 or 96, then it should be able to display Famicom RF. My CRT TVs handle it just fine.

Re: Oversize FDS disk images

We have a NES 2.0, why not an FDS 2.0? Here is how it could be implemented. The original fwNES FDS defined a 16-byte header, but only the first five bytes are used. The use of the first five bytes would not change in FDS 2.0. But the remaining bytes would. Here is how a FDS 2.0 header might look lik...

Re: Anyone has a real NTSC Incredible Crash Test Dummies car

This video https://www.youtube.com/watch?v=8x5IHXsJ2js was almost certainly taken with a real cartridge and shows "some jumpiness", but not as much as in FrankWDoom's video.
