Add the sound/beep.s example2026-04-10T11:32:44ZMiquel Sabaté Solàmssola@mssola.com2026-04-08T22:33:04Zurn:sha1:1978afbc18ffb227f0ce36663648e00d1d2d7945
This is the most simple example you can come up when it comes to
producing sound on the NES/Famicom. Basically, a single note is
delivered to the APU which is continuously on.

This was an oversight from the very first example that has propagated
into the other ones.

Put functions inside of the scope, avoid useless fallthroughs and be
more realistic on what is needed from elsewhere.

Be more careful on everything and try to follow along style.nes from my
repository. This might change in the future, but it's in a much better
state now.

Add a way to safely read from controllers2025-02-04T20:04:36ZMiquel Sabaté Solàmsabate@suse.com2024-04-02T21:49:52Zurn:sha1:3c6a583190b827c0e88e535d486a4f191ee255c0
First of all, move some reading utilities into the new `shared`
directory, so controllers can be read by more than one example. Second,
even if we keep the example on `basics/input.s` simple, let's provide a
safe alternative for the other examples.
