Re: NESRGB no video after install. Please help

I ended up resoldering all PPU points and it worked! I guess I had some cold solder joints in some of the pins that are hard to test (2-9 and 14-18) because they're not bridged directly to the motherboard. Also, I was using photos from old versions of the board where the CLK pin was one of the "dire...

NESRGB no video after install. Please help

Hey everyone, I've been trying to install the NESRGB mod but I can't get it working. Currently: - It shows a black screen through RGB-CSYNC with a palette selected (pin 3 and GND bridged).

Making nestest pass

Hey everyone! I'm new here, and as many of you, I'm trying to create a NES emulator to learn about its internals. I have implemented all the official instructions and I'll start reading to start the PPU, but first I wanted to test my CPU with `nestest`. I've added logs in my `.step(...)` method to p...
