19x19 update

Posted by Zach, 26 June 2006 · 28 views

Three years ago I would not have thought this kernel was possible.

[attachment=1183:attachment]

There is no game logic at this point. The program just allows three players to place their stones on the board, all using the left joystick.

Note that the cursor does not move into the top row yet. There is certainly room for improvement,...

Moving

Posted by Zach, 25 April 2006 · 15 views

If anyone needs to reach me, please be advised that due to moving, my internet access will be less frequent than usual. Four-Play is still on schedule, and is planned for release in a few months. I'll try to synchronize the release with any events that AtariAge may attend in the summer.

Finally Solved Marble Jumper

Posted by Zach, 18 April 2006 · 28 views

Tonight I finished off the last few puzzles. The most difficult by far was #19, where I was stuck for months:

[attachment=1014:attachment]

Even when you've solved all 24 puzzles in Marble Jumper it still has replay value, because you are not likely to remember all the solutions. Indeed I doubt I could complete #19 again without spending a...

Stella debugger question

Posted by Zach, 13 April 2006 · 7 views

I finally decided to wean myself off z26 logs and learn to use to the Stella debugger. It will obviously make homebrewing easier once I get used to it.

I am trying to set a break when PF1 is set to $aa. I tried the instruction below, and the program is clearly not breaking when the condition is met. Does anyone see what is wrong?

52-pixel bitmap tool

Posted by , 26 February 2006 · 15 views

[attachment=811:attachment](52 and 48 pixel Pac-Man logos by DEBRO)I have attached a tool that converts a 52-pixel wide BMP file to assembly code that can be plugged into a kernel. The BMP file should be set to 256 colors, but the program only reads it as monochrome. To set the colors for each line, you have to manually change the data in the C...
