Did a lot of troubleshooting… I swapped all the components from my board redesign back to the original motherboard I took them from in the first place, and everything worked on the original board. I even transferred my SOT353 LDO (since I’m not using the original N64 one) and that also worked...

Yeah it could be that too. I will look into that today as well after replacing the PIF. I checked all the resistances for the RAM and they all match up with a stock board but maybe I’m missing something. I feel like I’m close though!

I appreciate the troubleshooting suggestions. - Cartridge is in the correct orientation and even probed every single pin to the RCP/PIF to verify continuity and proper routing as well as did the same on a stock board for comparison. Actually did that with the entire motherboard. No issues. -...

Populated the board, started with the onboard regulators to make sure I get 3.3v and 2.5v (VTERM) and all was well. Continued to populate the rest of the components, checked everything under the microscope for bridges/shorts and probed various areas before I dare turn it on and everything...

I'm using the crusty old original one for testing. Confirmed the slot worked before soldering it though. I'm not 100% sure on the Hispeedido solution just yet. It does have a lot of pros though such as inexpensive, has a small circuit, draws low power, and looks pretty decent. It has worked on...

Boards arrived today, parts will be here tomorrow. Had some free time today so spent the last few hours probing every single connection on my bare board and compared to a stock N64 board and I’m happy to report it is 1:1 with no errors found (except a 3.3v and ground test pad for the...

Double posting due to too many attachments... Once I confirm the N64 board redesign works, I will continue work on reverse engineering the ED64 Flashcart. The ED64 Mini™ Layout is all over the place on the paper print out but wanted to see the scale of how much smaller it would be. Much...

I've been tinkering with the N64 on and off for a few months, think I'll start a worklog. Not sure what will come out of this, but hopefully a portable or maybe something that could help others. I've really enjoyed motherboard redesigns, a nice engineering puzzle for soothing the mind. So...

It has been a month since the last post, so quick little update. I have played through Metroid Prime and other light games here and there with the 1V and 1.15V line tied together running at 1.04v under load without any issues. All other voltages are stock, only the 1v and 1.15v were undervolted...

Thank you, that would look pretty dope!

Portable took a small fall, about a foot on carpet and broke some screw posts… So rebuilt it in PETG transparent red in hopes of a little more durability and higher heat resistance since I had found the case warped under the PMS2. Threw in Aurelio’s Direct Drive this time around and installed...

I’m not sure if Aurelio or Yveltal tried this approach in their board designs, but I have tried this approach many times still with no success. Voltages and resistances are all good, chips warm up like they should, but no actual boot. Still working on this though, and I do believe ultimately...

Awesome! I remember that portable from back in the day with the tripod screw mount on the bottom. Looks clean and I'm with you on them cool custom triggers!

I have thought about this too, but getting too close to 1V has caused instability from my testing on the CPU and if we tie both lines together, we would be slightly overvolting the GPU as the most stable undervolt voltage for the CPU has been 1.04V.I'm sure the GPU can handle the slight...

After many months of testing on 2 portables that I undervolted, I have found the 1V line doesn't like to be undervolted. My advice is to leave the 1V line as is and it's only a 0.3W saving anyway and doesn't seem to run any coller undervolted anyway, so it's not worth risking stability. These...

Nice to see the mandatory relocation requirements have shrunk!

These diagrams and scans are a work of art!!!

You the man Yveltal! Awesome work as usual, and man, the hours of work show! We appreciate you in this community!

Looking really nice, your OSD looks killer!

Thank you, and those are the ones!
