* or transfer to the respective media and run on a real machine (recommended).
*  - `flapple800.po` is the 3.5" ProDOS disk version (800KB)
*  - `flapple140.po` is the 5.25" ProDOS disk version (140KB)
*
* It should automatically boot ProDOS and load the color version of the game.
* There is a Monochrome version of the game included on the disk.
* To run it, quit game with the `q` key, and from the ProDOS selector menu
* run `fmono.system`.
*
* # How to build
* This was originally written to compile on Merlin 8/16, but it's now
* maintained using Merlin32 (https://github.com/digarok/merlin32/).
*
* - Classic Merlin16+ on an Apple IIgs
*  - Load Merlin, then `L`oad the file "flapple.s", finally hit OpenApple-A to assemble and it should build the "flap.system" file.
* - Modern PC builds:
*   - Assemble with `merlin32 src/flapple.s`
*   - Make disks with `./make_po.sh`
*   * Requires having `merlin32` and `cadius` commands available on your system.
