Behind the scenes of a C64 demo

I’ve only watched twenty minutes of this presentation but I’m blown away already. Up to about 15 minutes and a bit I was familiar with what he was talking about but then he got to the part about abusing the stack (neat way of saving cycles), and the jitter counter. That counter is insanely clever. I used to add small loops to wait for the right cycle or raster point in my demos.

I’m looking forward to watching the rest!

Dinosaurs of Computing

The Dinosaurs episode of This Developer’s Life struck a chord with me. Not because of Fortran or Dataflex although hearing about developers dealing with small memory constraints or attempts to convert an archaic piece of code into something shiny did make me grin stupidly.

No, there’s a bit about the Commodore 64 in there and some great SID chip music throughout the podcast. That sealed the deal for me! 🙂

If you thought software development was hard …

You should read about the development of a Ludum Dare entry called Ponk.

It’s a C64 version of Pong, developed on a real C64 with only a C2N datasette to save code. Back in the day I was lucky enough to have a 1541-II disk drive. I can’t imagine how painful it must have been working with a slow and unreliable cassette.

In the end he couldn’t transfer his game to a PC so he had to take screenshots of his game and OCR them, hand checking every byte. I did something similar about 20 years ago when I was tinkering with a C64 to Amiga cable and needed to somehow transfer a C64 programme from the Amiga to the C64 to do the transfer .. Painful.

Wow. Well done Sosowski. (via Indiegames)
