Sure, except for compatibility, which has always been a bit spotty since it is not a cycle exact replica of the original CPU and custom logic.


For custom chips I can agree, but you do realize that the Minimig has an actual M68k CPU on it, right? It's not in the FPGA (though for the Replay board and the Natami, the CPU is in the FPGA)

I am just wondering if this fpgaarcade/Minimig AGA device is going to drive the Natami to its knees and leave it in agony?


I think there's space for both. The FPGA Arcade Replay board is not meant for maximum performance - it looks like it'll do quite well, not least thanks to Yaqube optimizing the TG68 core (adding cache etc), but we're talking somewhere between  68030 and 68040 speeds here, while the Natami team appears to at least aim for something far faster. We'll see once they actually deliver something, though.

Does not require a real 68k in its design


Neither does the Natami. It has a CPU slot, but one of their goals is to use their own 68050 soft-core on the FPGA.

On the other hand the Natami:
Is closed source


I agree I like the open approach of the Replay better, but I doubt this is going to be an issue for most users.

Cost is near 700-1000 US$


What's that based on?

Hasnt got implemented the so called new features yet


My understanding is that SuperAGA is there, and that the 68050 is pretty much there, though they keep doing refinements. They've also got a lot of things such as a far faster memory interface etc.

We'll see once they actually demonstrates something, though.
