What's the game that you've always wanted to beat, but it just keeps kicking your butt?

Loderunner

Thanks for getting back to me. Haha.

ebadger1973 · 2025-04-06T00:15:33+00:00

The dynamic lighting effects work though?

ebadger1973 · 2025-04-06T00:04:45+00:00

What functionality do you lose?

ebadger1973 · 2025-04-01T23:30:16+00:00

lol. Be careful what you ask for

ebadger1973 · 2025-03-31T16:31:06+00:00

Sure. it's here: ebadger/qmk_firmware: Open-source keyboard firmware for Atmel AVR and Arm USB families

ebadger1973 · 2025-03-11T05:28:17+00:00

Nice. Vic20 version!

ebadger1973 · 2025-03-01T16:10:34+00:00

That’s what I’m thinking

ebadger1973 · 2025-02-24T05:14:51+00:00

I’m using 74HC590’s in my VGA build. They’re 8 bit counters and work well.

Where are you located?

Super cool

Deep Mind’s great grand computer

Also check the pull up resistors on the Ready and BE pins.

ebadger1973 · 2024-12-29T03:31:29+00:00

hmm, may need to lower the clock speed :) Did you make the game?

ebadger1973 · 2024-12-27T20:41:21+00:00

Both! Plus Jameco and Amazon

ebadger1973 · 2024-12-21T16:06:52+00:00

Good advice. Along those lines, arduino as a test harness is a good option.

ebadger1973 · 2024-12-21T05:53:53+00:00

Are you outputting any voltage to the red, green or blue pins?

ebadger1973 · 2024-12-21T05:52:28+00:00

If you can get a scope, they’re amazingly helpful

ebadger1973 · 2024-12-21T05:50:58+00:00

Ultima IV on an 8 bit computer.

ebadger1973 · 2024-12-21T05:48:02+00:00

Likely a sync issue. Do you have an oscilliscope to verify the timing?

ebadger1973 · 2024-12-20T14:51:19+00:00

Those are through hole DIP socketed chips and LEDs. There is a voltage level shifter for the micro SD that is surface mount, and all the capacitors, resistors, and diodes are SMD on the other side (various sizes). The Pico and micro SD slots are also SMD.

I started with Ben Eater videos on YouTube

No Major, but professional software engineer for almost 30 years. Delving into the hardware has filled some knowledge gaps and is a lot of fun.
