The Lynx "flabode" keys, Opt 1, Pause and Opt 2 are implemented using the
conio interface. The only characters the keyboard is able to produce are
'R' for Restart (Opt 1 + Pause), 'F' for flip (Opt 2 + Pause),
'P' for pause, '1' for Opt 1, '2' for Opt 2, '3' for Opt 1 + Opt 2 and

The TGI driver is implemented as a dual buffering device. To use it as a
single-buffer device set draw page and view page to the same value 0 or 1;
The TGI driver has a few Lynx-specific extensions.
Calling tgi_ioctl(0, spr) will display a standard Lynx sprite on screen.
Calling tgi_ioctl(1, 0) will do a flip screen. If you decide to flip the
screen then it may be a good idea to call the install-routine for the
joystick to get that flipped too.
Calling tgi_ioctl(2, bgindex) will set the text background color to the index
defined by bgindex. If bgindex is 0 then the background color is transparent.

At this point in time there is no support for the cart filesystem yet.
I have a cart_template example project that uses an interrupt driven
display, has support for the cart filesystem and an abcmusic sound
module.
At some point in time we may find a way to rewrite these to fit the
way the cc65 drivers require. But for the time being you can create
less portable applications using these Lynx specific modules in
cart_template.
