So do we know if anyone has tried to get in touch with the person to see about dumping the game? Other than wanting to try game myself like most everybody else here, I'd REALLY hate to see it eventually lost forever if the eproms finally give out and it was never dumped.

This is how I personally did it:

RAM adapter tests fine, and FDSstick and FDSemu both work fine on it as well.

So I got this FDS about 5 or 6 years ago stating it had the belt replaced. It's worked great and I've never had an issue with it before. Last time I used it a handful of months ago it worked fine without any apparent issues. With the advent of things like FDSstick and FDSemu, I've been using them fo...

Any idea when plastic shells will be available for this and/or FDSemu?

I was pondering modding in a switch to overclock my NES to eliminate/reduce slowdown in some games that have a more annoying amount of it. Only thing is I'm anal enough where the sound pitch change would drive me crazy. I was hoping there was maybe a newer solution I was unaware of, but it's become ...

I'm just going to go full nuclear option here: you could do it with a custom FPGA. You could make/modify an FPGA (VHDL/Verilog/etc) implementation of the NES that would allow this. However, if you're overclocking the NES, then you're already not compatible with previously made NES games (barring fe...

So let me state the theory thus far and see if it seems correct: 1.) Perform overclock on NES CPU (I'll refer to this CPU as X) mod per usual methods. 2.) Disconnect pins 1 and 2 (AD1, AD2) on X so that it is no longer outputting audio to the NES sound circuit. 3.) Take another NES CPU (i'll refer t...

Almost all the pins would be needed to generate audio, as NES APU port addresses are fully decoded. You could probably leave out the IRQ, NMI, and joystick pins, but that's it. Would that theoretically work though? I assume the 2nd CPU needs to receive all the same data (minus controller input) as ...

Would it be possible to do something crazy like piggy back a 2nd NES CPU with only the minimum amount of pins needed for it to generate audio (to hopefully not interfere with proper operation of the primary CPU). Basically my scenario in question is: 1.) Have the primary CPU overclocked (with a swit...

I've read that supposedly the HDMI NES has this feature built-in, but I prefer NESRGB as I like to get 240p output that I can hook to a CRT or to my XRGB3 if I'm in a HDTV mood. Most NES overclocking information I'm finding is several years old, so I'm wondering if there's a more modern method I'm u...

I'm very appreciative of devices like this and loopy's FDSstick. I enjoy them both, but I wonder if it's possibly to implement auto-disk swapping like flashcarts do. Now I don't know the low level behind the scenes workings of the FDS and its bios so I guess I can only speculate ways I'd imagine for...

Goal: A method to play FDS games with perfectly accurate 2C33 audio without using FDS disks (eliminating need for moving parts). Basically, I'm chasing a perfect solution for playing FDS games that will work for years to come. Using the FDS drive with real disks works currently, but since there are...

Not sure if this or the hardware subforum would be best, here it goes. So, a handful of months back the fan translation for Lagrange Point on Famicom was completed, but due to the special chip/mapper in the cart it is not currently compatible with any NES/Famicom flashcarts. I've seen some people ta...

The FDS adapter is supported by the TNS-HFC NSF playing cartridges (e.g. http://www2s.biglobe.ne.jp/~tns/nr26740601.html ). The bandwidth of the FDS is only serial at about 70kbit/sec, so a microcontroller should be able to keep up. A few people have requested such a device in the past, but most en...
