How to detect WinUAE

[demolition]

Whenever I move my CF card from the Amiga to WinUAE, I have to comment out the ACATune line in S-S, as it will not boot otherwise. Is there a way to detect WinUAE and only run acatune in case it is running on a real Amiga?

[Toni Wilen]

Something like this should work:

version >nil: uaehf.device 1
if warn
; no uaehf.device found
endif

(do not attempt to use any side-effect to detect emulation, it will break someday..)

[demolition]

I get an error if I put that in the beginning of my startup-sequence: 'version failed returncode 20'.

[Codetapper]

You'll need to add the "failat" command above the version command.

*shrugs* i haven't been able to incorporate this, but then again, i fail to grasp the most about the Amiga...

[Codetapper]

Add "failat 200" to the top of your script, ensure failat is in your c: path (with WB2.x+ it may already be in ROM) and it should work fine! (It just means that an error of 200 or higher is required to break your script).

What's the highest fail - I never used higher than 21 in my s-s.

OK = 0
WARN = 5
ERROR = 10
FAIL = 20

These are the defined return values. A bad program might return anything between 0 and 4294967295, though.

Perhaps you like this small program.

Run it like this:

DetectUAE
IF NOT WARN
   ACATune ...
EndIF

Thanks a lot Thomas mate.
I was seeking a solution like this as well, since ACATune nowadays, report that it found the board (ACA1230@28 if chipset=AGA or ACA620@25 if chipset<>AGA) even if it doesn't exist = WinUAE.

This solved the problem once and for all

How does it work? Also by detecting if uaehf.device exist?

Edit: And thanks Codetapper, it now works as it's supposed to.
For reference, the S-S part looks like this:

failat 200
version >nil: uaehf.device 1
if warn
  acatune -maprom devs:kickstarts/kick40068.a1200 >nil:
endif

It checks if any hardware with vendor ID 2011 is in the system.

There is no guarantee it stays the same in future. It probably does but it still isn't guaranteed Nothing outside of emulation needs to directly access emulated boards.

Manufacturer (vendor ID) 2011 is reserved for "Hackers" like prototypes and developer boards so that is not unique for WinUAE!
