We got to get that chip on the A1200!


I'm surprised no one ever made an Akiko compatible card for the Clockport... ;-)


-Edit- Actually I'm surprised I never thought of it before  :-o

Hmm... you might also need to patch the Kickstart ROM (graphics.library).  WriteChunkyPixels() uses Akiko on the CD32, but not on the A1200.  The question is, does it detect the presence of Akiko and use the appropriate routine, or is it hard coded depending on the version of graphics.library in the ROM?

I assumed that one would program it the "old way" by using it's hardware regs. But that said, I've never seen any technical documents for it, and I don't know how the software Akiko Emulation worked on the Squiriel drives

I do not think any emulation was used. Games would have there own workaround or it would fail.

Apparently not many games used Akiko, so it is not a big problem. Shame though, it is supposed to be quite good :-(


The Manufactured claimed there was Emulation.

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.

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.
