Dance Dance Kung Fu Pixel

Not many updates lately. One of the big reasons is I tried to finish a Commodore 64 game for the Forum 64 and Protovision Game competition 2017. The whole game is done within a 12×21 pixel resolution spread across most of the screen (including the borders), by just changing the border color. While extracting the … Continue reading →

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!).

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?).

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 →
