Wrote a Donkey Kong (and Jr) Test ROM

[SNESNESCUBE64]

I've written quite a few freeplay mods at this point but I had never written anything from scratch. I decided it would be fun to write a diagnostic ROM for Donkey Kong hardware. It runs RAM, ROM (just prints checksums), NMI, DMA, and audio tests on startup. It also provides controls, dip switch, and basic video function tests as well as some crude monitor test patterns in the run time menu.

I am still writing the manuals but with the long weekend coming up I am hoping to finish the manuals over the next couple days. After I'm going to give radar scope the same treatment

You can find both my source code and compiled ROMs on my github.

Test menus (same on both DK and DK Jr for the most part)

Monitor test patters (as they appear in DK)

How did you get the last 2 screens to appear? I was not able to find them.

Hover over monitor test in the runtime menu, use left and right on the joystick to select monitor pattern, then press jump to go to the patterm. Which pattern is selected will be shown by the number on the right side.

Thanks, that works.
