I have made a BASIC interpreter for the Nintendo DS. I call it Wee Basic. It is DLDI compatible and includes a demo BASIC program to show you the available commands and syntax. Best of all you can program on the DS itself. I will be posting more information when I get an opportunity, including a more detailed walk through of the demo program.
Note that I cobbled the editor together very quickly & I will have to better it over time & iron out some bugs.
Download the file using the link below and change the extension from ppt to zip before opening – using ppt was the only way I could upload it to this blog.
As with all homebrew, use at your own risk.
