On December 29th 1990 (exactly 24 years ago) Jakob Veje Hansen, Jens Andersen, Bjarke Kjærhus Larsen and I finished the Idiotic demo for Pulsar. The Demo participated in the C-64 demo competition at the Dexion X-Mas Conference held at Højstrupskolen, Odense / Denmark.
The demo wasn't released at the conference as we had to fix a few bugs here and there. Time went by and 24 years later I decided to fix the demo as a little project for the retro party held by Teddy René Hansen not long ago. First things first, so I had to dust off my good old trustworthy C64 and Morten Skov was so kind as to fix my good old Final Cartridge II. Amazingly the C64 and the diskdrive still worked. Having the hardware in place I had to look at the software side of things...
Of course most of the source-code was lost and all I had to work with was some partial data here and there, some linked parts which didn't work etc. So, first of all I had to re-read the 'Programmers Reference Guide' for the C64 and re-learn 6510 assembler programming. Next I had to reverse-engineer the linked parts in order to extract the data (graphics, sound etc.), then recompile whatever source code I had, bug-fix the code and then finally put it all back together using "link'n'crunch 2.0" by my old buddy Jesper Juul (still a magnificent tool). Then I had to crunch the demo using Time-Crunch 4.2 (it's amazing how slow that process is). Finally I had a working version of the demo - digitally remastered after 24 years. Michael Englyst was so kind as to transfer all the data from the C64 into a .d64 image so I could take a few screenshots on the PC.
Going through this process I came to appreciate how much programming, tools, computers and user-interfaces have evolved in the past 24 years - not to mention the speed. On the other hand, my C64 boots in a few milli-seconds and I can turn it off instantly - so I'm not really sure we're quite there yet!
On a final note, the music was made by Drax / Vibrants. |
