How to speed up emulated Amiga OS 3.2.3 in WinUAE?

[Snowwie]

I have created a nice OS 3.2.3 environment in WinUAE.

But, the emulation is very slow and (like on the real Amiga) if you have maps full of a lot of files (ten thousands of mod files or whdload games etc) then even on my pc the emulation is pretty slow.

I do know that it's not the read speed capability since the Amiga partition of located on a Samsung 980 Pro m.2. SSD, which is more than fast enough.

In the real world we use accelerators on our Amiga's to get them faster. But even with a TF1230 on my current A1200 loading times of heavy filled maps still takes a lot of time, even with the CF card mounted to the TF1230 (which has a much higher data throughput than the onboard IDE).

What do I need to make WinUEA faster? Can it emulate an accelerator? I already use Picasso to get a better image clarity, but this does not help with speed.

Below are all my settings in WinUAE:
I don't think I find the answer in 'hosts', maybe somewhere in "Expansions"?

Edit: Also after changing those settings I get this message:
So it wants a cpu.library and gives me the instruction to insert the Install 3.2 disk.
Then it generalizes say to install the cpu libraries (but not "how"), of the cpu 'board vendor'.
How can I know who the 'cpu board vendor' is? This message is not giving me, well, proper instructions.

What exactly do I need to do?

Change the CPU to a 68060 for starters ...

Also look to change the OS icon.library to use this instead:

Aminet - util/libs/IconLib_46.4.lha

aminet.net

Makes Icons appear a lot faster

Or use JIT and everything is nearly instantaneous.

As above, unless you use jIT it will run pretty much the same speed as real hardware.

I will test these options out.
But will WHDLoad games still run normally even if the simulation of the OS is beefed up?

 

[miggymad]

Yes, most games use their own internal timings and speed settings so they'll run just fine

For example, try running Frontier: Elite II both using the 68020 CPU then the 68060 CPU settings. Sit back and watch the intro animation, spot any differences?

Jit cannot be used in combination with the first screenshot I see from Miggymad?

You need an 060 library in your libs drawer, depending on what accelerator you're emulating. If it's the Blizzard then you need the phase 5 library.

You have to turn off MMU.

Yes. So you boot off the 3.2 Install disk. Go to install 3.2, inthe install menu you should have the option to install “Thors MMU library”. Select this option and then It will ask you to insert the Thors CPU install disk. Install this and you are good to reboot back to your installed 3.2.
