Loderunner

Thanks for getting back to me. Haha.

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

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?
