Basilisk II, SheepShaver, Mini vMac, SoftMac don't support resolution switching.

Fusion PC does.

case solved
you just have to delete the .opt file
fixes both full and demo in all resolutions

I have managed to run Fusion in 512x horizontal resolution, so I updated my previous message.

I just used univbe and 512x384 works in Fusion PC 3.0 now.

Is it possible to set Operating System to 512x384 resolution on System 7 on real computer?
Fusion PC 3.0 only allows the choice of: 640x480, 800x600 and higher.

I have also tested Prince Of Persia 2 demo version in Fusion and it has 640x, 800x, 1024x, 1152x and 1280x horizontal resolutions with distorted screen, while 512x looks ok.

I have also tested Prince Of Persia 2 full version in Fusion and it has 1024x, 1152x and 1280x horizontal resolutions with ...

Ok, thanks anyway! I already have Sheepshaver with 9.0.4, and Basilisk II with 7.5.3 installed, just thought running Prince of Persia 2 on Mini Vmac would run the music at normal speed. Oh well, I'll take what I can get! Thank you anyways!

In Mini Vmac and in SheepShaver you can use the same hdd ...

BasiliskII and Sheepshaver allow it every pixel

It looks I have found the solution:

I have checked minivmac v3.2.3 and v3.4.1 and they behave same way as v3.5.8 with 512x and 640x horizontal resolutions.

But what is important:
Even though your building program says horizontal resolutions are allowed every 32 pixeles
v3.5.8 actually allows it ...

I have also tested Prince Of Persia 2 demo version in BasiliskII and SheepShaver and it has 640x resolution with distorted screen while other resolutions (including 512x) work ok.

just in case, i am getting this during compilation:
1>ADBEMDEV.c
1>d:\2\minivmac-3.5.8-wx86\src\ADBSHARE.h(89): warning C4456: declaration of 'p' hides previous local declaration
1>d:\2\minivmac-3.5.8-wx86\src\ADBSHARE.h(55): note: see declaration of 'p'

I have tested Prince Of Persia 2 demo version in SoftMac and it has 640x resolution with distorted screen while other resolutions (including 512x) work ok.

This would mean it is not a game problem but the emulator problem.

I have noticed that cause of some reason Prince of Persia 2 demo has got two right most vertical lines removed making intro doesn't look nice. That was somewhat changed in full version where it is removing two vertical lines from the middle of the screen (line 17 and 18 from the right) so that it is ...

I have also tested Prince Of Persia 2 demo version and it looks only one horizontal resolution is making screen distortions in intro/cutscenes:

512x

All other resolutions (including 320x, 640x, 800x and 1600x) look correctly.

It is easy to test as it is the first screen of intro that is distorted ...

I have tested Prince Of Persia 2 with lots and lots of horizontal resolutions and it looks only the following ones are breaking cutscenes:

320x
512x
640x
800x
1600x

All other resolutions work OK.
Why is Mini vMac treating above resolutions in a special way?

Cause of some bug in Mini vMac, Prince Of Persia 2 has messed up graphics in introduction and some cutscenes when played using normal resolutions.

Hence I have hacked Mini vMac this way so that all cutscenes are being displayed properly.

Game uses 510x384 but doesn't look properly in 512x384, but ...

Prince Of Persia 2 The Shadow And The Flame works nicely in Mini vMac 3.5.8 when you use a slightly modified resolution. I have enclosed a build I compiled on Vogons forum.
