I created a Chinese Word Processor for the Commander X16, the 21st century 8-Bit computer of the 8-Bit Guy, TexElec, Perifractic, Michael Steil, Frank van den Hoef, and Michael Allison. I go over the steps I took to create this word processor and discuss certain details of programming the X16 in 6502 Assembly.
This program was able to go much farther beyond the scope of my last Chinese Word Processor I created for the Apple II, in that it now includes saving and loading of Chinese text files, along with the ability to scroll the file down to 120 lines of 40 columns Chinese (or 80 column English) text.
One of the main programming highlight is how to interact with different VERA registers, and I go over several tricks I learned while working with them, including setting up a graphics layer in tile or bitmap mode at the proper resolution, copying data from one part of VRAM to another, editing the default color palette, and much more.
