imho, for starters it is pointless to have special purpose hardware, requiring dedicated programming instead of your genuine 68k binary sitting behind a tight bottleneck on your system. but think whatever you will, its yours.

errrrr,

Looking VERY MUCH forward to getting that standalone.

For once I agree :)

I can confirm this works fine with the Vampire:

Usable as "you can write texts in an editor while playing". And this is no "my thingie is better than yours"-discussion; I don't profit from Prisma sales. We just want to know things, ok?

 
  prisma has only very tiny buffer on the card which needs to be constantly fed to gaurantee continous playback. the transfer is pio.
 
  developers actually communicated that this was a problem to overcome.
 

Yes, we did. :)


  taking this into acount, do you really want to say, feeding data to prisma costs no cpu time, even though a 68020 may be enough for it in most cases, which in comparison to what apollo provides is a fraction not to be bothered with?
 

Too much interpretation on your part. I also really don't understand your argument - a 68020 only has to push data over the port while a 68080 without a Prisma has to do the decoding part as well. So the question for me was: Can the Vampire decode compressed audio faster than pushing data over the CP. Gunnar calculated, that the core could be put to better use by decoding the audio itself instead of pushing bytes over the clockport. That's plausible, especially if we picture the Vampire getting faster with each FPGA generation. So the question has been answered. A real life verification would be interesting, though.

On the other hand: There's currently no (easier) way to play FLAC/MPEG-4AAC/etc. than just adding a Prisma to the system and starting AmigaAMP. Even if you have got a Vampire.

I've run into an issue with the A501 on my A500 the game Mortal Kombat seems to be unable to detect the additional ram on the A501 and refuses to boot due to the machine not having 1MB with the Vampire installed.

Does it work without the Vampire installed (and with KS3.1)?

If you have the A501 mapped to chip mem it may not be supported if the game looks for 512k memory @ $c00000.

The A501 worked immediately before the Vampire installation, I've not modified the A501 or the A500 in any way other than removal of the battery in the A501. I'm not sure where Mortal Kombat looks for the memory but I don't think it looks for chip mem I could however be wrong. I'm using whatever KS my Vampire shipped with earlier this month and I currently have no way to upgrade the core.

The V500 doesn't support the SlowMem cards (A500 trapdoor) right now. It's being worked on.

Good to know, I've seen that the A501 can be modified to map to FastMem would that make any difference in this case or not so much?

You can add to the list the SUM internal USB keyboard adapter: EXTERNAL LINK 
It works perfectly with the Vampire II.
