Installing an unsigned application in /Applications (automagically) will probably be prevented by Apple's security mechanisms. ~/Applications will probably be easiest and cleanest, and I would also prefer ~/WUDSN instead of ~/jac - makes it easier to find ... If you provide Altirra as part of the package, I would put Alitrra in the directory structure parallel to WUDSN so that it's possible to re-use it for other purposes as well without having to find it somewhere in the directory structure below WUDSN. (JDownloader does this with unrar2 etc., so you might end up having it twice on your drive unnecessarily).
Anyway, thanks for the effort, I really appreciate this!
@Mathy: That would of course be great, but I'm not sure to what extent Altirra makes use of Windows' graphics/screen libraries which may be very specific to the OS. Then again, if a WINE emulation is around 30MB only, it shouldn't be too hard.
Is the new MADS version available for download anywhere? The project's home page still only has the 2.07 version online...
I never wanted to as well, but once I had a MacMini (first at work), there was no way back to Windows for me. Linux is still nice® for programming, but having a consistent user interface that only changes in minor things over the years plus the underlying Unix background is really the best compromise for me - but I disgress ...
I have used WineBottler (http://mike.kronenberg.org/) - in the advanced section you can set a few parameters that will create a self-contained Alitrra app. Most important are the libraries that are to be in- (or ex-)cluded as these can save a lot of harddisk space (well, a lot is relative nowadays). Unfortunately, it's been so long ago that I did this that I forgot which sections in "Winetricks" I activated. I could send you my Alitrra App so you could have a look what I removed from the App directory structure to save space.
Later on, it is sufficient to replace the altirra.exe (and maybe the help file) within the app bundle when updating Altirra (one of the reasons why I never really wrote down the install settings).
