Programming Equivalents

This is a conversion utility to change hex to decimal or binary to hex or whatever combination you need. All you do is put the number you want to convert into the appropriate box (type it or paste it), then hit the Enter key or left click anywhere within the gray utility area to see the results. This tool was improved by bogax at AtariAge in a few ways, including the interactive byte section at the top of the tool.

Reversed Playfield Variables Normal


The tool above is for batari Basic users who want to draw small areas of the playfield. The standard playfield uses 4 variables for each row (8 bits x 4 = 32). You can access these variables directly (var0 through var47). The second and fourth playfield variables of each row have a reversed bit order, so the tool gives reversed numbers to the left and normal numbers to the right. Decimal and hexadecimal numbers are displayed (choose your favorite).

About the Playfield Toy

This is an old graph of the playfield in case anyone needs it. You must have JavaScript enabled to use it. Click inside of each box to toggle the color. It will also create playfield data for you below the graph, but the playfield editor in Visual batari Basic is much better. You can change row height, row colors, copy and paste, preview in emulator and more. Although the VbB playfield editor is better, I'll still leave this playfield toy here for those who can't use VbB. If you want to clear the graph and playfield data, simply refresh/reload the page.
