The 19x19 board

Posted by , 01 December 2005 · 10 views

About 2 1/2 years ago, AA member Atari Rescure Group asked in the forums whether Pente was possible for the 2600. At the same time I had been starting to think about how to port Go. The board I proposed back then was a monochrome 80 pixel wide sprite using flickering.I've...

Four-Play with simple AI

Posted by , 27 November 2005 · 7 views

I've applied the classic minimax search to Four-Play, and I'm pleased with the results. The program will anticipate any traps within 7 moves and act accordingly. I was concerned that it might take a long time to search 7 moves ahead, but it turned out not to be too bad.The AI is not terribly difficult to beat at this point because the...

Catacombs of Mu

Posted by , 23 November 2005 · 46 views

I think I've found my next homebrew project after Four-Play. It's an original concept, and the attachment is a rough prototype that doesn't do much...In the remote mountains of Kashmir, maverick treasure hunter Jack Rascly has found the final resting place of the last survivors of Mu, the ancient empire which sank into the sea 12,000...

Threshold 2P

Posted by , 08 November 2005 · 13 views

Here is an unfinished project of mine to hack a classic title into a two-player cooperative game. I've had the idea for a couple of years now, and wanted to keep it under wraps until I had a finished game to show off. Unfortunately it was easier said than done.The idea was to bankswitch between two nearly identical copies of a game and to...

Scanline timing diagram

Posted by , 27 September 2005 · 27 views

I don't know if this has been done before, but this diagram is the secret to my time-sensitive kernels. It shows every clock and every cycle of the scanline. No more adding up cycles. If you know what your kernel needs to do at a particular point, the code almost writes itself!I've attached a blank diagram, and an example filled out...

Archon is possible.

Posted by , 19 September 2005 · 27 views

EDIT 09/29/05: The ideas and mockup in this post have been made obsolete by recent developments. Supercat has produced a new demo, and I have designed an alternate board. See this thread for details.Many people have thought about how to port Archon to...

1K puzzle game almost finished

Posted by , 18 September 2005 · 12 views

[attachment=359:attachment]As a treat for those of you who read my blog, here is a sneak preview of my 1K puzzle game. I've tripled the number of puzzles from the first version posted, and added a musical reward for winning. (thanks to Paul and Wolfgang ;)) It wasn't easy keeping the scanline count stable when resetting and selecting,...

Four-Play: playable demo

Posted by , 07 August 2005 · 2 views

Work on my board-game homebrew is going well. The current demo is a fully playable two player version where both players share one joystick. The controls are simple: push left and right to select a column, and push down to drop your piece. Use reset to clear the board. The rules are simple too. The winner is the first player to get four in...

4-In-A-Row DOS demo

Posted by , 17 July 2005 · 19 views

I worked out the AI for Vertical Four-In-A-Row and put together a DOS program with a text interface that plays a pretty good game. The next step will be to implement the AI in 6502 assembly. Then it's on to finishing the kernel (see previous entry) and making an interface.You take turns with the computer dropping pieces into an upright board,...
