What settings can be changed on-the-fly?

[Foebane]

I've discovered that I can adjust certain settings, like Display options and the CPU Emulation Speed slider without having to quit WinUAE and restart, but I'm wondering which ones? Turning on and off JIT would be handy right there and then, but I think changing CPU would require a restart, which I always do with Ctrl-F11.

Also, what about the Restart button, does that restart the whole emulator as if I'd used the Quit button? I've discovered in the past that it still remembers the previous configuration even if I select a new one, so I tend not to use it.

I think it's for restarting virtual Amiga, not emulator.

"Reset" button does that. And LeftCtrl with Insert+Home as well.

JIT can be changed on the fly as long as originally started CPU mode is JIT compatible. (68020+, no MMU). It is (generally) on the fly supported if config change does not require replacing hardware or type of hardware.

Restart = stop emulation, return back to GUI with config unchanged.

Thank you, Toni, that's brilliant. It means I don't necessarily have to restart the emulation or the program I'm running if I see a problem, I just hit F12, make the changes, Start and there it is, fixed.

This also seems to work with the Chipset as well - I just tried running a demo that works mostly with the Quickstart A500 configuration, but needs an ECS Agnus: demo ran until the glitch showed up, F12, select ECS Agnus and Start and the glitch disappeared and I didn't have to restart.

This is really useful to know!

Chipset change is not really officially supported, it does not modify everything (especially if switching to/from AGA), it is mainly debugging option that enables to see OCS/ECS glitch differences easily.

Note that you can also change config inside the emulation by using uae-configuration Amiga program. (Search the forum if you want more information)

Yes, I noticed that with an AGA slideshow - switched from AGA to OCS and back again to see what would happen, and it didn't quite work (not really surprising as AGA is so different compared to OCS/ECS) but this is an extreme case and just a test, but it did work with two OCS demos (out of all my A500 demos) that required the ECS Agnus.

EDIT: No, just checked again, there were glitches there too. I think you mentioned that in post #4, with the hardware, unless that was something else.

I've just spotted that there's an A500 configuration for ECS Agnus, so that's that sorted.

Is there some kind of way of assigning a key to toggle JIT on and off directly, without even going into F12?

I've got a list of demos I'm having to go through and determine if they work better with or without JIT, and at the moment my only option is to write a list of what demos need JIT turned off, but it would be a Godsend if I could just start any demo and toggle JIT the moment I saw any problems.

EDIT: I found the solution at this thread: http://eab.abime.net/showthread.php?t=35360
Already tried it, and it works beautifully!
