Pong on the Game Boy!
This small game is designed as a demonstration for Delwink's libstdgb library for developing for the Game Boy. Since Pong is the "hello world" of game development, I thought it would be well-suited as a test of the library's capabilities and the readability of its API.
You'll need the GNU Make, Small Device C Compiler (SDCC) and Wand for Python 3. On Debian-based systems, you can install as follows:
# apt-get install make sdcc python3-wand
After that, just run
$ git submodule init $ git submodule update $ make
Finally, you'll have
pong.gb which can be run on an emulator or flashed to
your programmable cartridge.
If you get a syntax error while compiling, try
$ make CFLAGS=-DINT_BOOLS
On older versions of SDCC, the
bool type doesn't work properly, so I added a
way to use integers as boolean types. It makes the binary a bit larger and the
computation slower, but it should still work.
Match the style you see in the code. Do not use spaces for indentation.
Since the Game Boy is a very limited platform, code is expected to be written
for binary efficiency. If you're just getting into Game Boy development, try
mixing around nested
if checks, and evaluate when pointers can efficiently be
used, and check the output of
gbromgen to see how your code affects the
