| I bet they are very low (as in "slideshow mode" low) for now, but it's an incredible achievement all the same.

| I saw the video. Yes it was a slideshow. No surprise there. BUT IT WORKED! :) Hats off to the developers on this.

Femu 0.10 has achieved the next compatibility milestone. Note that femu is not an FPU, femu only allows programs requiring an FPU to run without.

Is it faster than the non fpu version?
If so then even more impressive.

| Pure integer version should theoretically be always faster, because its needs to execute less instructions than FPU emulation.

I guess you mean remake the who engine to not use FPU?
What i meant to compare with was the version from this topic

| Surely a problem with no FPU is that the assembly code (which on 68k is geared toward being easy to read and write) becomes more obfuscated when trying to do floating point in integer

Hello and thank you to all the team for your great work.
Now that Quake works with FEMU I suggest you test this.
4 years ago, I recompiled Frank Wille's quake68k v.2.3 source code (68060 non ppc) with an option to view fps in real time. Link to the QUAKEFPS file:
EXTERNAL LINK
After running QuakeFPS and launching a new game, in the console, type : "show_fps 1"
The top right will show the number of fps.

I meant in the general level. To emulate one FPU instruction needs many INT instructions. If you have INT version, better to use it.

Sorry I could not get it to run even on WinUAE, it complains that it does not find the AGA. Anyway, to make sure that we understand right of the purpose of femu, my answer would have been femu allows/does not allows it to run, without screen capture.

| Just wondering, any chance we might see a hardware FPU with 12 months? Not looking for a promise, just an indication if it's even on the cards?

I am not part of the team, but ...
Its likely we will have Apollo FPU that might be used in new apps, likely in V4 Vampires.
This means that 080 will be able of fast FPU operations with its optimized apps, but no 8882 compatibility there.
But it might be able to have some software assisted Motorola compatibility (like FEMU using that FPU) is possible.
That you will get 68882 in chipset or FPGA is not even planned,
its not easy to do and might even be legally troublesome.
Most likely is that FEMU (software emulation) gets improved in speed and compatibility (currently 881 16Mhz speed or so) and I hope gets integrated to Kickstart ROM / ApolloOS which would effectively solve the FPU prob to end user.
That is my personal understanding of the situation.

Your understanding is all wrongV4 will of course have 68882 compatible FPU.

Mine was based on what was publicly known up to this moment. This news looks better. But, now will people hold you on to that!

| I've done some testing also with FEMU on a demo and it seems to behave strange on 2 scenes of the demo. for helping a little bit on the last frames of the video if you pause there is a report with the scenes fps so if you can check and improve something its good to know.Can this be fixed ?
The video is here :

recording was made on V600 v2 X13 core using FEMU 0.10

Hi Gunnar,I never doubted it, but there are PLENTY of people (well, 4 or 5) stirring the pot over this, so it is terrific to see it stated crystal clear as to the action the Apollo Team intend to take. Case closed!! A MMU, I couldn't care less about. I prefer not to have one. Software existed before it, it can still be made in the future.

MMU is already here to map adresses and soon Kickstarts on fly :-) Just not backward compatibile. Some tool for debuging/virtual mem on Vampires only should be written.

Thank you for the response Gunnar, good to hear about the V4. Am I to undertstand from this that the V2 will not get FPU? Or is it still uncertain?

Sorry, but that's just dense. With MMU support you have a complete solution and no barriers to adoption.

What mission critical hinderance does not having a traditional Amiga compatible MMU cause?
