So you replace very underpowered hardware with underpowered hardware

nice progress

the demos are to a very high degree Amiga system friendly?

Well by system friendly, I meant the operating system, not the hardware. Hardware more often referred to as a platform, or hardware platform. To be more precise.

If Demo is made for AGA Amiga1200 platform, it means it is probably, not going to work on OCS Amiga500 platform.

It also means that adding graphics cards or sound cards is also pointless, because the demo or game does not care if you have upgrades.

And I have seen many demos that uses Hi-res interlace screen resolutions.

Well yes there are, but they are mostly used for splash screens (sometimes even interlaced), (often while de-packing, pre-calculating), or just as something nice to look at, It's not often you see hires used in demos while you see visual effects.

It's 4 times the Arial, it takes 4 times the CPU power to show the effect.

Anyway, I liked the part of DEMO using HAM picture with hardware sprites, nice creative touch.

Idea: "x86 on A1200 accelerator board emulating 68k"

I've been meaning to make this suggestion for a while, to see if anyone can explain why it's a stupid idea that couldn't possibly work...

Surely it ought to be possible for someone with electrical engineering knowledge to take a really cheap x86 SOC on a custom board, or even something like the Intel Gallileo, with a minimal (user-invisible) OS running nothing but WinUAE's 68k emulation (with JIT) and interface this to the Amiga via the trapdoor slot... to effectively appear like any other 68k accelerator card?

I'm sure there are good reasons why this wouldn't work (timing-related?), but have never seen this suggestion raised...

Anyone able to shoot this idea down, or think it could actually work?

I remember running WinUAE on a 400 MHz PC back in 2000 and being amazed at how much faster it was than the real thing!

I imagine even a modern ARM chip could do it...

No 68k JIT for ARM, yet.

Why not use PowerPC SoC for the very same purpose? There is 68k UAE JIT for PowerPC and you could run AmigaOS 4!

@DruggedBunny

I've suggested it in a couple of threads in the past but it's never resulted in a technical discussion, or much discussion at all, for that matter.

In theory it's possible, but realistically it doesn't make sense: just use WinUAE on a PC to emulate a super Amiga 1200 or 4000.

@NutsAboutAmiga

You have to remember the Amiga is more than the Workbench disk, it contains both the hardware and the kickstart too.

This 64k intro runs in hi-res. Not just a splash screens, disk loader or static screens.

There's already one, for the UAE4ARM project.

WinUAE is better.

@NutsAboutAmiga

So "games and demos" is the only good use you have for Amiga? That is sad. I suppose demo coders are in PAL land, and hence have little interest in 640x480.

@cdimauro

The real thing is the best option in my opinion, then comes Universal Amiga Emulators as next best option, and at the bottom comes those half functioning fake Amiga wannabe carppy Amiga unfriendly so-called NG systems.

Thanks! I missed this one.

So ARM, PowerPC or x86 SoCs are available for such idea.

No (reliable) 3D, no compositing... and alien OS in background.

Your words are even more amusing in this your latest "incarnation". Keep up good work!

Have you tried using AROS, MorphOS and OS4, and what makes you think they are fish like?

His previous personality answered: no. It is sometimes hard to remember all his names.

Why?

Do you know math?

y = f(x)

f = the thing which generates results given inputs
x = the input
y = the result

I, user, give x and f makes an elaboration and produces y. Simple, right?

So, applying the same concept, as I user I only need to send x to something which produces the result. And, in the end, I enjoy the result. Full dot.

That's the ONLY thing which counts: no "religion", no "philosophy", no "ideology". Only the final result.

Yes. Unfortunately, x64 is still missing.

Well, if you put an accelerator board on an Amiga 1200, you have also no 3D and no composition.
Quote:

See my previous message: what counts is only the result.

Anyway, in theory it's possible to realize an Amiga emulator which is also an o.s.: it directly boots from the BIOS or UEFI, and takes immediately control of the computer, emulating the Amiga. No "host" o.s..

Is it fine?

What fish?

How good is the compatibility with the Amiga computer and it's software? What are the system requirements for each OS?

Can you run Amiga system friendly software such as the demos I linked to on these operating systems without emulation?

And before you try to say AROS has Amiga compatibility, just so you know, i tried the included AROS ROM file in WinUAE once and it crashed WinUAE so much I had to quit WinUAE with the task manager, something i can't remember i have had to do before, it didn't even get to the startup-sequence i think.




And most important, what do these NG OS have to offer i don't already have on my fair-priced PC? It's got to be really good to justify the price, especially when it comes to OS4.

With BVision - you have 3D, with Mediator/Radeon 9250 - you have 3D and compositing... and FrankenAmiga.

Quote:

YES!

@pavlor

What FrankenAmiga?

BVision is designed to be easily installed inside the Amiga 1200 case, even a soundcard fit inside the A1200 toghether with the BVision. But you should also install WarpOS, CyberGraphX, Warp3D, StormMESA and Ahi to making use of all the additional capabilities. And you don't lose compatibility with other software like you do with AmigaOS4 and MorphOS.

I don´t think the same applies to Mediator.
