The CGA colour palette specifies that colour 6 is supposed to be Brown but is shown as Dark Yellow.

I may have a possible idea how to fix this by treating the Green intensity value differently as I found a possible FPGA pin I can spare.

Hello @yeokm1 - Sorry for opening issue in your Repo and not in the TubeTime Repo, maybe you can answer my question.
Its about original GG. Your GG HDMI is in Production, so i dont tried it yet.

I flash with a little bit different UM-FT2232H Module, because its much cheaper in Germany.
The Problem which i have are the missing 3 Pins
V3V3 to VIO strap
VBUS to VCC strap
V3V3 to VIO strap (2)
which are not there on my UM-FT2232H Module

I already posted a question in the original GG Repo:
schlae#22

To my Problem:

I could flash 2 cards without this 3 PINs - anything was fine.
Now, it flashes without errors, but at the End i get a Message that Flash and File are different.
When i try the card - it doesn't work. Somehow the Flash ROM is messed.

Maybe you have some Ideas with:

• what to do with 3 missing pins
• how to solve the flashing problem
• 
  
  

Thank you very much!
