My CRT has died :(

Yesterday my good old 29" Sony Trinitron KV-X2901D CRT has died.   It has faithfully served me for about 20 years, for watching TV and developing all my Atari 2600 games.   R.I.P.   I will miss you.

Star Castle brainstorming

With the recent thread about the never to be released, new Star Castle homebrew, I first tried to understand from the available videos and screen shots, how it is done.   The rings and gun are drawn using the 48 pixel routine, using large, precalculated ROM blocks. I described that a bit more detailed that in the very thread. All other objects are probably drawn with the ball (though I am not 100% sure here).   The result looks pretty impressive, but there is one pretty obvious difference f

Source code found in ROMs

I was a bit bored this weekend, so I had a closer look to some games. A lot of games, especially from Taiwan, contain garbage data, which is unsed by the game itself. Often this garbage contains traces from the game development, sometimes even snippets of source code. In this entry I will post some source code findings.

The Sentinel in 2D

When reading some stuff about one of my old C64 favorites "The Sentinel", I wondered if something similar would be possible for the 2600. Since 3D was sure impossible it had to be in 2D. Attached is a very preliminary result.You now watch the game top-down, your own position is at the bottom of the screen. Your sight is limited but you will be(!) able to rotate in 90° (maybe 45°) degree steps. For the heights, various colors are used, starting with dark magenta, then blue, cyan, green, yellow, o

IFA 1981

While doing some research on my Atari 2600, I came to IFA 1981. It was that exhibition were I first played a game of Asteroids on the Atari 2600. And a few weeks or (months?) later I bought them both.   On the very same show, I accidentally stepped by a booth were I watched something completely new to me too. At that time I did not know where this came from, but a few years later I found out. http://www.youtube.com/watch?v=_pqvjfW9yHo&feature=player_detailpage   What I had watched was
