Famicom controller in a NES

I have a few perfectly working controllers I have removed from a HVC-001 and that I want to use on my NES-001 and HVC-101. I've searched the forums but haven't found anything about this. EDIT: Through the internet I have found this: https://www.raphnet.net/electronique/famicom_to_nes/index_en.php Wh...

Re: Famicom stopped working - Recommendations?

Yes, I borrowed a multimeter from a friend. I followed what Fisher told me to test, so I made diode testing on all the IC's. I found that removing the CPU made voltage increase a bit, but it seems there's still a short circuit. I started de-soldering the suspicious ram chip but the desoldering unit ...

Re: Famicom stopped working - Recommendations?

Haha I see you are from Brasil! :) :beer: happy father's day to you too :) I desoldered the CPU and quickly measured the 7805 output. The outputted voltage measured around 3,7 volts. I was desoldering the ram and my unsoldering unit started working bad. I will try to fix it and go on tomorrow. Will ...

Re: Famicom stopped working - Recommendations?

@FIsher: So I've done the diode test, using the thread you suggested to me. I used the image in this post for the names of the pins: https://forums.nesdev.com/viewtopic.php?f=9&t=16305&p=203042&hilit=diode+test#p201653 Even if some chips have slight different names and numbers I used the pin names f...

Re: Famicom stopped working - Recommendations?

Alright, I did some testing and noticed a few things: When I tested the Famicom turned off, plugged to the PSU: - The power sub-board seems to work correctly, I followed the power flow up until the on-off switch and it was all ~5v. - Just in case I checked if there was any voltage in the mainboard, ...

Re: Famicom stopped working - Recommendations?

Thanks a lot for the recommendations. I'll start today after work :) About USA SNES, PAL SNES and SF PSUs, I think there might be AC/DC differences for different regions actually. I bought this PAL SNES in Germany a few months ago, but all my life I've used USA consoles exclusively. My original cons...

Re: Famicom stopped working - Recommendations?

Well, I replaced the regulator. It's outputting ~5v, but still not working. The tube tv reacts every time I turn on the famicom, but the screen moves a bit only. This is looking a bit bad to me :( Thanks for all the help so far. I will spend some hours this weeked trying to learn how to debug the ci...

Looking for people that wants to start some projects

I'm looking out for people that wants to program some videogames for the NES. I'm looking for people that knows how to program in assembler 6502 and know how the NES works. I know how to program in assembler, but I'm not much familiar with the NES cpu. I know some basics, but I will need some help a...

Re: Famicom stopped working - Recommendations?

Well, I'm actually measuring the output pin and it's indeed ~12v. The input pin measures ~13v. It's good to know that the boards are original. Hope I can repair them. I thought about the av mod but with the broken regulator its probably not the case. I never got any audio output after the "incident"...

Re: Famicom stopped working - Recommendations?

Okay, I got a multimeter and tested the thing. First I did a good cleanup of the cart slot and still didn't work. Now, as I've checked some videos on the internet and seen the famicom board, I noticed that the circuit for the power management is different than the ones I've seen, so I think this mig...

Re: Famicom stopped working - Recommendations?

Thanks for the answers guys! About the cleanup - yeah, I thought about it. It's really hard to clean the famicom connector and games. I purchased the famicom and several games just recently and who knows if they ever were cleaned. Tomorrow I will give them a deep cleaning and try again... But with m...

Famicom stopped working - Recommendations?

I purchased an original Famicom from japan (ebay) two weeks ago. Today I received the package and connected it to my tube tv. As I currently live in europe and original power brick is AC100v input, I plugged it in with my Super Nintendo power brick which has similar specs (9-9.4v output) but it didn...
