FPGA options for the A1200

[grond]

is there any idea about when or if we'll see any with Vampire levels of performance?

If there is going to be an FPGA accelerator for the A1200 with the same or similar speed as that of the Vampire, it is going to be a Vampire. It's not that FPGAs are magically fast at running 68k code. The other 68k softcores reach low to mid-range 020/030 class speed (without FPU and MMU, of course) in comparable FPGAs.

Or someone else improves the other 68k softcores. It's not like vampire is magically the only fast FPGA 68k emulator.

Apollo likely has a headstart, but you don't know what people are doing in private.

It's impossible to improve the existing other 68k softcores to the level of the 68080. Write a new one, yes, that's always a possibility. Albeit a very unlikely one as there are few microprocessor developers around that would spend several years worth of their sparetime for such a project.
