rottexpr-openal: Fork of rottexpr using OpenAL

[Cacodemon345]

https://github.com/Cacodemon345/rottexpr-openal/

This fork of rottexpr switches to using OpenAL for sound playback.

Features:
1. All features of original rottexpr.
2. Now able to use OGG/FLAC files as replacement!

Read the README.md file in the repository for instructions on how to build. Only MIDI music playback is implemented as of now.

Shroom Mode sound reverb isn't implemented; the code to do so is not pleasant and doesn't translate well to OpenAL's way of doing reverbs.

 

MIDI music playback requires a soundfont named "soundfont.sf2" to be stored in the directory where rottexpr is started.
