Scroll the "PCM" slider to see all the wavetables of the GameBoy's "wave" audio channel, used in Pokémon Gen. 3. The "volume" slider is self-explanatory (but note that the value 3 is only available on the GBA). https://turbowarp.org/1351009826/fullscreen?hqpen&fps=60&limitless&offscreen&clones=Infinity
Thanks to Pokémon RSE Decompilation for letting us know the graphics and sounds used ! The GBA allows 64-entry wavetables, but they are separated into 32-entry wavetables. The wavetable are 4-bit (0-15)
