Bitmap Creator for Apple ][ hires sprites/bitmaps

title

An Excel Spreadsheet to virtually create and render Apple ][ bitmaps/sprites. Works too with Calc in Libre Office/Open Office.

Fill in Apple ][ hires screen bits on a spreadsheet to create reusable bitmaps and sprites for your Apple ][ software development. Use the copy/paste features of spreadsheet to easily create pre-shifted shapes. The spreadsheet renders the bitmap as a real Apple ][, computes all the bytes values (so you can copy/paste them in your program) and even generates POKEs commands to type in Applesoft so you can see how it renders in your favourite Apple ][ emulator.

Instructions are included in the spreadsheet.

Also, an article about Apple ][ hires. Including some interesting 6502 tricks.
