Let's make a Pi Pico 2 powered video card.

It helps not to wire your DRAM address pins backwards.
Still major issues to iron out.
We're getting there. Still have an issue with alignment of glyphs and attributes.
I'm not sure how, since my latch signals for characters and attributes match the simulation. But baffling bugs are the best kind of bugs.

its still kind of weird seeing like, readable text on a monitor, and knowing this isn't IBM or Tseng Labs or Cirrus Logic it's just GloriousCow.
I made a video card?? you can just do that? isn't it illegal?

There's a lot of ways I could just change the way the card works that would probably be absolutely fine and would be less of a pain in the ass to implement and debug, but there's something pleasing about matching the schematics.

I made it worse
@gloriouscow this is a fundamental experience of outputting video out of an FPGA lol
