Recently, a friend of mine asked for advice on modding his N64 to allow for hdmi output as he was using one of the cheap AV to hdmi adapters and not getting very good results.
This gave me the opportunity to test out the Hispeedido N64 mod board.
This mod comes with a nice ribbon cable, making it a fairly simplistic install. Although I would say this is not for the beginner and a digital microscope is pretty essential with this one to see what you are doing.

I lined up the ribbon and then used some kapton tape to hold in in place whilst soldering, making sure to use plenty of flux.

Once everything was installed, a small cutout to the case was needed to allow for the mini hdmi port to be accessible on the back of the machine.

After this, it was time to put everything back together and check to see how the device performed.

Overall, I was pretty impressed with the quality and I would say it was on par with my NTSC RGB modded SNES which I used to have hooked up via an OSSC. So for the £35 the device cost, I would say it is very much worth it.
It even has a built in menu which can be accessed by pressing Start+A+B at the same time. This gives a few basic options of changing some colour settings and also the aspect ration.
if you have the ability to do fine soldering, then I would definitely recommend this mod 😀

Nice, you did a good job. I may have to get one myself and do a poor job 😉
It went a lot better than I anticipated 😅
