Re: converting PAL NES to NTSC

Thanks for the responses - yes the NTSC pad (JP5) is closed, not the PAL ones. I have read of other people having many troubles with clone PPU/CPU and NESRGB installs - so suprised you are saying you have it working well, glad you have done this tbh. Have you left these units powered on for some-tim...

converting PAL NES to NTSC

Hey nesdevvers, I have worked on at least 100 NES consoles, many of them NESRGB installs or other misc repairs like faulty chip replacements, so I have spent a fair bit of time under the hood of NES consoles. Since I had a bunch of PAL NES consoles (living in Australia) I decided to try and convert ...

Re: how to remove dip chip perfectly?

Memblers is spot on. Whenever I am going to remove a Nintendo CPU/PPU I re-flow every pin with some solder, after putting flux everywhere. Then I go and use my desolder station on each pin. I heat up each pin, then kind of move the tip of the desolder gun in a circular fashion whilst on the pin to p...

NESRGB audio input/outputs mixed with Twin Famicom audio

Tims NESRGB board does a really nice job. It also does a nice job improving the audio out by means of the O, A and B pads on the NESRGB PCB. I have just dug out my TwinFC and RGB modded with a NESRGB board - but I thought, I would like to use the improved audio mixing circuit on the NESRGB, but also...

Re: nesrgb colours wrong using RGB/YUV although composite wo

thanks lidnariq and Tim Worthington for both replying to me ! The problem with the YUV was that the power or GND on the YUV board was not soldered all the way through :oops: and the problem with the RGB Blue line was that the DIN connector I was using was not effectively poking into my Framemeister,...

nesrgb colours wrong using RGB/YUV although composite works

After having successfully installing a nesrgb in my FamicomAV, I wanted to put one in a clean pal NES I have. After finishing installation + installing the component board I was surprised to see really strange colours when using component and off-colours using scart RGB ouput, but composite from the...

Re: Perfect FDS 2C33 audio when not using actual FDS disks?

New update is up. I fixed the problem with Tototek 3206 write mod chips and made some other changes that should make disk reading and writing more reliable. Wow nice stuff loopy, I did however accidentally rip up a trace on my FDSStick while upgrading to 128MB so I have ordered another from tototek...

Re: Perfect FDS 2C33 audio when not using actual FDS disks?

:P I am waiting for a new pair of flush-cuts to arrive before I attempt this. Kazmat, can you tell me the process you undertook to swap it over, I have not had to swap out such a small chip before - I really don't want to wreck it. I do a lot of soldering work and pcb modifications etc but just a bi...

Re: Perfect FDS 2C33 audio when not using actual FDS disks?

New software update is available (Windows GUI). Supports larger flash, and boots to a menu (credit to deadbody for inspiration ;)). I'll throw the source up on github, it may take a few days to get it organized. Awesome job the menu is really handy. I noticed the following ; -menu lists games you h...

Re: Perfect FDS 2C33 audio when not using actual FDS disks?

I don't have a 3206 drive to test with. Would the modchip have the same effect with a 7201? cut the traces to the write gates on a 7201 !? blasphemy :mrgreen: :mrgreen: i'll send u a 3206 if you send me a 7201 :wink: --- I tested out using diskhacker and such apps with my chipped 3206, it appears t...

Re: Perfect FDS 2C33 audio when not using actual FDS disks?

Hi evilsim, Thanks for the reply Tomy, I understand that fdsstick and this chip don't work yet. I am happy to wait and see if a new firmware on the fdsstick will resolve this problem. Like I said I have 4 FDS drives, one of them is in a TwinFC and 3 loose FDS units, one being a 7201. If there is an...
