* Add the sound/select.s exampleMiquel Sabaté Solà2026-04-102-0/+236
| | | | | | | | | This is an iteration over the sound/beep.s example, but it covers three channels instead of just square 1. Moreover, you can use the joypad to select which channel you want to hear and, of course, you can combine them all at will. Signed-off-by: Miquel Sabaté Solà <mssola@mssola.com>
* Add the sound/beep.s exampleMiquel Sabaté Solà2026-04-102-0/+197
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. Signed-off-by: Miquel Sabaté Solà <mssola@mssola.com>
