If that is the case, then:
1) cgx/picasso96 applications won't work
2) no truecolor modes
3) no chunky modes, for example updating single pixel on 256 colour screen requires 8 read-modify-write cycles

Even if you would optimize the blitter and memory accesses processing everything in planar would still be horribly ineffective.


Nothing is stopping a cgx/picasso96 driver from being written that will handle these cases, and it would integrate seamlessly with native modes, sprites, draggable screens and all.

As expected.

I remember I used to run HAM8 screen for IBrowse back in the days :)

What software would benefit from chunky modes anyways, apart from quake/doom ports and mac emulators?

But it would be the fastest thing around for DPaint! :laughing:

Wanna bet? I see lots of legal stuff standing in the way along with a bunch of nay-sayers :hammer:

Legal problems?

Who owns what nowadays anyway? And who wrote the uaegfx driver for WinUAE?

And yes, I remember the nay-sayers from when MiniMig was announced... :p

Ok, here's a wild idea. Put a soft-powerpc core in the main FPGA and run AmigaOS 4.1 on it with native chunky screen modes.

That's been proposed and ultimately discarded for the time being.  Most OS 4.1 games are SDL ports that could be recompiled for a fast '060 or the '050 softcore without difficulty under a native port of SDL.

P96 was bought out by Hyperion Entertainment when they started making AOS 4.0.  Cybergraphics is owned by the MorphOS team.

I predict that it will be as Cybergraphics compatible as AROS is, since most of the code that is going into the AfaOS code base comes from AROS anyway.

I respect Piru's opinion and technical knowledge, but I also respect the work Thomas and crew have already completed and their plans for the future and I can only guess that they are comparing apples to oranges.  The expectations of one are quite different than the plans of the other.

I know there has been a good deal of criticism against the Natami team for some claims and plans that have been put forward in the past, but not everyone on the Natami forums, or even the dev team knows which direction the project will ultimately go, so I just dimiss some of the more outrageous claims and fanaticism from a few at the Natami website forums.

I like the progress that is being made and still like the idea of what they are trying to accomplish.  Only time will tell if I will be able and still want to purchase a Natami board when they are finally released.


Edit:  I like the idea of buying a supercharged MiniMig that has faster cpu and aga graphics than any Classic Amiga model ever had.  If the AGA chipset emulation also has additional features, other than just being faster at all color depths than the original Amiga models, that will be an extra plus, but not a make or break item that I have to have.

How are you helping the Amiga community? :)

Natami is all about running and reliving the Amiga experience on NON PC, non emulated enviroment. It's about the excitement of the Amiga trademark fusion of software and hardware capabilites. It's that illusive "it just feels right" feeling of it all, but better, faster stronger...That's the kind of  Amiga experience I want to be connected to. A PC, or XBOX running emulation is great but this NAtami is a special thing.


that's exactly why I bought Amiga OS4.1 and a Sam flex :-)..kudos to Natami team..looks great!

I'm waiting for Natami to change my Amiga 2400 x86 and switch to a real Amiga.

Just think about it... we'll have new expansion cards, startin with 060 then switching to PowerPC cards! Graphics cards et all! NatAMI is the future!

I count on you guys!
Amiga 2400 x86 owner

Amiga is in my heart and in my mind...
