Not Work (N64 - Revision 03)
I used an F-1 World Grand Prix cartridge as a donation and only kept the 4kb save chip. However, there is no signal in the game, I have already tested all the contacts on the cartridge, there are no broken tracks, I have recorded the firmware several times and nothing, not even the test ROM works.
What could I be doing wrong?
My Nintendo 64 board model is 03. I've already tried powering directly via the USB-C peak and nothing either.
not even the test ROM works
Start there and get the test rom to work first. Check your soldering and signal integrity.

I tried running the test rom several times and was unsuccessful. I measured each point from the peak to the plate pad and they are all ok. I spent several hours trying and nothing. Not what could be wrong.
I updated the build environment and made stable releases end of October, please try with those. If those don’t work, the root cause is probably a hardware problem.
I've done the same and it works fine for me (didn't realise anyone else was doing this janky set up haha!).
I've found that if your grounding is loose it doesn't like to work, or it works very intermittently. So, worth a go if you are sure you're otherwise hooked up correctly.
Remove the capacitor (if it has one) and make sure that the VCC isn't making any unintended connections across any of the diodes that are usually on there.
Does the light on the pico turn on when the N64 is on? If not, then focus on your VCC connection. Careful not to back feed the USB's 5v into the 3.3v on the N64 VCC as well.
