This is a QR Code generator for MS-DOS. It requires an 8088 CPU and a CGA-compatible graphics card. The application is based on the C++ version of Nayuki's QR Code generator, adapted to compile with Open Watcom 1.9 and run under MS-DOS (or DOSBox).
The project is meant as a demo for experimenting with QR code generation. For smaller QR codes, my NEC V20 takes about 15–20 seconds to generate one.
As QR codes require text to be in UTF-8, the input text is automatically converted from your system's codepage to UTF-8. Currently supported codepages are 850, 852, 858, 866, 737, and 437, with 437 as the fallback.
- Generates QR codes in CGA 320x200 mode.
- Supports UTF-8 encoding with automatic codepage conversion.
- Compatible with MS-DOS and DOSBox.
Start the program with your text as an argument. If the text contains spaces, enclose it in double quotes.
