New A-EON Music Card for Classic Amigas

[spirantho]

The chip in the Prisma is well documented, so it's quite easy to use. I'm more than happy to help provide pointers etc. for using it.
You could make your own interrupt routine without the OS and spool from RAM very easily.
I wouldn't recommend killing the system if you can help it though!

this is the result of advertising it as a "sound card". no wonder people expect sound card functionality. if it was advised as an audio stream decoder the expectations wouldnt be wrong and people would not ask "stupid questions"..

It's not a stupid question at all, but it has been answered repeatedly in this thread.

I agree the thread title may make people think it's like a Delfina or something, but I can't change it, sorry.

Or wire the Prelude output into the aux input on the Prisma. Best of both worlds. You could chain them with Paula audio too!

It still could be better at mp3 playback than a delfina. Is it?

I've never used a Delfina but I believe it struggles on high bit rate mp3s... the Prisma will happily play many more formats including 320Kbps mp3.

The aim is using UAE as a dev env of course it's to improve the music of existing games for the so called classic.

It would be easy to make a Prisma.library that actually redirected to a software mpeg player. You wouldn't want to lose the OS though in that case.
Arcade games wouldn't benefit easily but something like Monkey Island could be done, I guess. Same with Sierra games.

Is the Aux input on the board or backplate?

I can't say, I afraid. Mine just has a wire as it's a prototype.

At the moment it's only using the A1200's clockport address, but if you need me to add another address I don't see a problem with it.
