Why no FPGA accelerator cards?

The problem is the content. There is no 32-bit 68k CPU core, FPU or MMU (yet) to program into it.

Add to that the price of the FPGA (at least 2x as expensive as real 68060 for something that might be able to match performance).

See the NEXT part... meaning it has not been done... if it ever is done then there is a chance someone might make an FPGA accelerator card... but unlikely. At that point you may as well replace the whole Amiga.

and is 100% compatible (and a lot faster)

Why even bother posting stats like that? Never going to happen.
Compatibility with the OCS core is getting much better thanks to Yaqube's hard work but lots of subtle undocumented "features" must be implemented. Not to mention similar things for AGA. High compatibility can be aimed for... but in the short term.... you'll have to live with gfx & sound glitches and crashes not present on the real Amiga.

Plus when you go "faster" in a system like the Amiga you're going to lower compatibility. There is no getting around it.
