webN64 is a JavaScript/HTML5 port of LazyUSF2 a player for "(Ultra) Nintendo 64 Sound" (based on Mupen64plus). Please be warned that this emulator is not the most stable one, and some music files actually manage to crash it.
The music that is currently played as an example is from the game Wipeout64 (Copyright by Psygnosis). May it bring back some good memories of that franchise and I hope there are no objections to using it here as a test case.
Bring your own .miniusf/.usf files by dropping them onto the page (you'll have to drop the .usflib first - before dropping the song files that use it). Respective files can be found for example on modland.com.
The audio is directly calculated within JavaScript by running the Mupen64plus emulator and then played using the WebAudio ScriptProcessorNode infrastructure.
This is one of about 30 music players that I have ported to the Web over the years. To hear them all in action visit my PlayMOD page.
