Re-hacking the 80’s-part 6: code online

Re-hacking the 80’s-part 5: training run

<previous part Training run For a change of pace I decided to use a few of my trainers (and my new map feature) to try and finish this game for once (never reached the end before!). At first I implemented the ‘never lose your sword’, ‘giant invulnerability’ and ‘endless lives’ trainer options. Regrettably I played … Continue reading →

Hacking the 80’s-part 3

<previous part Music This part I’ll be writing about ripping the music from the game (‘hacking, ‘cracking’, ‘ripping’ the vocabulary of the scene sounds a bit like a pro-wrestling pre-match-rant, doesn’t it?). One of the reasons the C64 was so popular, was because of the great soundchip and the music that was produced for it. Hackers ripped … Continue reading →

Re-hacking the 80’s-part 1

What? Thirty years ago I cracked a game. This is a first post of a series about trying to improve on that piece of (in this case relatively harmless) criminal activity.

Shaving a Yak for Christmas

A few months ago I acquired a Commodore128 computer. An old 8 bit computer from the 80’s. It came with a Star NX-10C dot matrix printer, which I didn’t really know what to do with. But with the coming holidays I thought it would be fun to print some Christmas greeting cards with it. I thought it … Continue reading →

Someone used one of my cartoons in a blog article  about devops. Not a bad article either! It does make me curious how people find my cartoons. Maybe a simple Google search on cartoons and devops is enough. Anyway, here is the link: http://blog.christianposta.com/devops/devops-and-the-myth-of-efficiency-part-i/

C64 browser plugin test

A while ago  I found a C64 emulator in javascript. I seemed an ideal substitute for the JAC64 browser plugin, because Java in the browser is hard to get working nowadays. I had a lot of trouble getting the javascript module working and performance was not very good under Chrome. It didn’t help that I had trouble … Continue reading →
