The Manufactured claimed there was Emulation.

I think they only meant general CD32 emu on an A1200, I could be wrong though.

[Jose]

Wing commander is mentioned as the only one that used it in some CD32 FAQ pdf file I found.

Ok we have two then on the list:
- Wing commander
- Microcosm
.....


The cool thing would be for someone to test both these versions on a simlar specced A1200 and see the difference in speed.

By the way does anyone know how much overhead does a good  C2P software conversion cause, say on an 60/50 for example?

Check out this line of the SX32Pro expansion description @ amiga-hardware.com:

"The unit supports DMA transfers at up to 40MB/sec by using the Akiko chip."

Now how cool is that? :-) Akiko turned out very useful as far as the SX32Pro CD32 expansion/accelerator goes.

[Jose]

Hmm, doubtfull, shouldn't that be 40Mb/s (= 5MB/s) ?

[x56h34]

Oh, so you think that they were actually referring to 40 Mbits per sec other than Mbytes? Could be...

@Jose

Depending on the skill of the coder, between 5% of the CPU to 15%.  (I've seen some bad coders get 30%+)  Also depends on the resolution, how much chunky data there is, etc.

Does Akiko replace the Gayle chip, or are they completly different?

[downix]

Very different jobs.

[Radfoo]

So there is no Gayle in a CD32?

You see, I was wondering if something like this could be fitted to a CD32. No good without Gayle though :-(

[Stedy]

Does Akiko replace the Gayle chip, or are they completly different?

Akiko replaces Budgie and Gayle.

It provides the interface between the CPU and custom chips and to the Cd drive. It also contains hardware to speed C2P.

All the info I extracted from the CD32 service manual on Akiko is at

I have an SX32 Pro and FMV card............I am absolutely Dying to have these both inside the CD32
at the same time! believe me, it's possible.........anybody wiling to do it? you just have to make a circuit board with a passthrough...........I dont kno squat! about circuitry so I dare not do it with my own CD32......already have blown like 3 of them.

The FMV card ware huge, and used to hang out of the back of the CD32, it was also really quite crap, since it was essentially a standalone unit (it had it's own Decoder chip, it's own graphics chip and it's own video out ports) :-(

A PPC upgrade for the CD32 would be far more useful.

 What in the world are you talking about?  I have a FMV card and it does NOT hang out of the CD32.....thats only the little loopback peice.....the card itself is completely engulfed by the CD32.....i have already installed it and the SX32 at the same time and it fits..........you just have to remove the sheilding and the metal case off the MPEG card......now I only did this to make sure it fits so that when someone makes an adaptor for it, that I know it already fits.
And the FMV card for the CD32 by the way is the BEST FMV card I have ever seen for any system........and the only one that played CD-I Digital Video Discs (The first version of VideoCD)......Philips made the highest quality VCDs at the time.

This card is great and is someone figured out how to access it from Workbench, might be able to get it to play MP3's.........I have already enabled it to Play VCD's from workbench when using it with the SX-1

[bloodline]

Ok, sorry, I'm in a bad mood today :-)

But the card is still a "blackbox" video/audio decoder, the Amiga has no ability to access it and use it within the Amiga environment.

@Downix

U sure? Even at 640x480? Ok forget it, that's far too few to be worth it...

[mantisspider]

customising an A1200 to have the akiko chip would rock if anything actually used the chip.
