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 →

<read previous part Unbugging the past In this part I’m going to describe how I removed a ‘feature’ of the game that I consider to be a bug. Backup material But first: Maybe you imaginary readers would like to have the disassembled source I use, so I uploaded the currenty version. I still add comments … 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. Not sure if it will interest anyone or if anyone except bots is reading this blog, but I’ll just pretend there is an interested … Continue reading →

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 →

Still working on my C64 drawing tool

just broke the main functionality and have to think how to convert my old files, but there is progress. Next features will be full screen bitmap with sprites that can be positioned across the screen, expanded in the X-direction and put behind the bitmap. And some bitmap font feature would  be nice. And while working … Continue reading →

More progress

Still working on a cross platform super hires C64 drawing program (looking for suggestions to make the description even longer). Drawing works pretty good now, just needs a bit more intelligence. I can export the sprite layer, but must work on the bitmap layer/color layer. When drawing a random line I was reminded of a seventies … Continue reading →
