Awesome project, congrats!

I "discovered" DOS 25 years ago, not sure what's your point?

Hadn't heard of them, thanks for the links!

Good point, OpenWatcom is obviously miles ahead of Turbo C, but it's also much more complex. I tinkered with it for a while, and ended up using the latter for its simplicity.
DOSBox can be easily installed on any system, you can save the entire C: in a git repo and it'll probably keep working in any number of years from now :)
Meanwhile, OWC doesn't have packages in popular Linux distros, only a custom binary installer, and on MacOS it doesn't even have that.

Targeting 8086-level of instructions was actually my first idea. It wasn't possible with gcc/clang, but Turbo C is freeware these days, so... ;) In case you're interested, see https://github.com/luke8086/nf/

I'm not sure if defaulting to 32-bit instructions would still allow calling BIOS, but good point!
In this case the design goal was to show the easiest way to jump into C and start building the actual application, so I just tried to avoid any trickery (even enabling the A20 line)

I feel your pain, so sorry that you still need to support the .code16gcc hack! My first approach was actually to avoid GCC/clang altogether, and use Turbo C instead. It came with its own set of problems, but the output was much more predictable. In case you're interested, you can find the code at https://github.com/luke8086/nf

I created one such game [1] a few years ago and had plenty of fun. I'm pretty shocked to see an actual book published specifically about this niche topic. I haven't read it, but I hope it gets some recognition, because IMO toying with 8086 is one of the best ways to get into bare-metal coding.
