VGMStream supports pretty much every console stream format known to man and several that aren't, but it's gotten less and less source-available as it's progressed (mostly due to laziness by hcs rather than malice, I think, but it makes it hard to keep updated).

I just noticed that in 2.0, the NSF channel toggles don't work when playing .nsfe files.

For example, Shovel Knight.

...safe to say this is dead?

How does it compare to let say BZR?

The proposed latest M1 if it even happens might end up being an Audio Overload/M1 merged played gone to the extreme so there is still hope for it yet.

That is because new MAME source code has XML's for games from many systems as it's merged with MESS now and it also has the CPU and Audio sources for those systems.

They can also add the CPU's and Audio Drivers for the PinBall MAME and Fruit Machine MAME into it to make the MAME Music Drivers source even more compete.

I'm hoping for the best from the new M1 direct audio games player. We can even listen to the tracks that didn't make it to the game as long as the music is in the source still and all that nerdy goodness and all in direct lossless quality to how it was programmed unlike a Mega Drive .vgm or .gym for example which is a logged file so might not sound as good as if you load it in M1 direct.

So yeah I'm hoping the new M1 could use the MESS sources for an extra Audio Overload style of advantage for at least cart based games if not floopy based AMIGA ones too for harder to crack game music games which havn't even been put on Exotica as the music is so hard to crack from some copy protections out there which a direct audio player would bypass due to accessng all the possible audio slot placements on the disks directly.

Hopefully we can get this new M1 source code going soon as I just want to see all those new possibilitys from the new combined MAME/MESS sources in action and perhaps when thats working the special PinMAME and FruitMAME versions added as well so theres a working audio source for those machanical games not working in the MAME/MESS source.

What are you even talking about, the current version of M1 supports shitloads of pinball games, it has for over a decade now, where have you been

Is the source code available anywhere?

AO itself is not, but the majority of the players its based on do have available code.

AO can't be open sourced as it stands because there's a fair bit of code in it where the license precludes open source release. One of these days I'd like to get back to it, but real life has gotten in the way.
