Stupid Invaders sound and music

[wuya]

Hello everyone,

I'm currently trying to understand how to decode music and sound files for the game Stupid Invaders.

A demo is available to download here if you want to give it a try.

So far, I'm pretty sure the codec is some kind of raw format.
Playing .adp music files in ffplay using the pcm_zork codec at 11025 Hz produce a sound very close to the original.

If anyone want to try it out, any help is welcome

Can you upload a sample? archive.org is really slow for me

Hello Savage,

I've uploaded samples to Dropbox.
I hope the download speed is better. If you only want to download the musics, download the Stupid_Invaders_Music.7z file.

Strange works with ffplay but ffmpeg gives error
