I dunno, UAE has some pretty nice features. On my machine, it supports modern SATA-II hard disks, DDR3 memory, gigabit network connections, high end sound and graphics. Those are pretty good features, really.
I'm not knocking natami, but the main advantage it seems to have is that it is a piece of hardware you can actually hold in your hand.
Yes of course this is a major advantage.
Having a small system which just boots only AMIGA, which you can turn on and off as you want - is just nice
Regarding the different between UAE and NATAMI.
First of all:
UAE is a great piece of software - I love UAE -
I think it very much depends whether you are mainly AMIGA or mainly Windows guy.
When you are a 90%-Windows/10%-AMiGA guy or gal then UAE is a gift from heaven.
You use you PC for Windows mainly and play a bit with AMIGA OS from time to time.
UAE is free - bingo.
If you are 90% AMIGA guy then having to have a huge and power hungry machine that loads gigabytes to boot up only to emulate an AMIGA is a bit of a pain. Especially if the 2 GHz and 200 Watt eating PC runs AMIGA slower than the NATAMI HW.
NATAMI is real HW which continues the AMIGA spirit.
To me the AMIGA spirit had a lot of elegance and efficiency.
AMIGA did had DMA based sound, DMA based Copper, DMA based Sprites, DMA based Blitter etc.
NATAMI is a real AMIGA so every is DMA based again.
On AMIGA audio was "free". It did not cost any mentionable amount of CPU time.
How much CPU time does 100% correct AMIGA audio emulation in UAE?
How much will it eat if you emulate not 4 voices but 8 or 16?
How much CPU time does 100% correct emulation of sprite and playfield collision take?
How much would it take if the screen resolution is not 320x200 but 1280x1024?
How much CPU time does emulation of the AMIGA Blitter take?
How much would it take if the NATAMI Blitter is 120 times faster?
How much CPU time will emulating of the new 3D Blitter take?
The point is UAE can emulate an old A500 or an old A4000 by brute force.
The NATAMI is to fast to be emulated by bruteforce.
Good examples to me are the new game we are working on.
For example, look at the new 194x screen shot on the NATAMI website.
The new 194x game is much to demanding for UAE.
It could not run smooth on any PC with UAE. (At least any PC available today)
With todays fast PC you can easily emulate an A1200, that clear.
But you can not reach NATAMI performance in software emulation - not even with todays PC.
Certainly at some point you also emulate an NATAMI in software when PC are 10 times faster or so.
The NATAMI is no PC killer - of course not.
But its a faster AMIGA, much faster than the old A4000 or even UAE.
Cheers
