I got boards made and parts to make a TiltAudio like 18 months ago but the price for Raspberry Pis was crazy because of the shortage so I held off. Now Pis are back to reasonable prices, you can now get a Raspberry Pi Zero 2 W w/ a header for $23 shipped. I assembled a board, purchased a license and made the discovery that TiltAudio only supports altsound files and not PinSound files which is a real bummer. Besides sound quality the best part of an aftermarket sound solution is alternative sound packages.
Quoted from lucky1:Pinsound considers the folder structure and ALL the sound packs using it as THEIR intellectual property. That is why steve implemented the altsound structure into tiltsound which was introduced into pinmame (virtual pinball) when Pinsound started scrambling "their" soundsets. From the vpin community there
is a altsound soundset for almost every machine supported by pinmame (and tiltaudio). Just google for altsound and use that format for your new projects.
Reading through the entire thread I see at some point there where downloadable files to descramble some sound sets and then those files got baked into the base image at some point and removed from the website. Is descrambling still included in the code? If so what games are supported? I assume not but it would be good to know for sure.
Is there anyway to manually descrabmle a community sound file? I have the permission of the person who made the sound file but I do not know how to go about it. It would greatly improve the value of my TiltAudios.
