TO clarify somthing about prince of persia. That game uses IRQ 7 not 5 and I don't think you can change that. Just felt like I needed to repeat myself. So ya IRQ 5 isnt going to work for that game. You might find a lot of guides out there of people saying oh IRQ 5 about everything becasue that is the defualt port SBlasters used. But thats not really right. Pretty much every game lets you use IrQ 7 as well, and some games like prince of persia are hard coded for 7. So ya dont fall victim to that. Also you might need to use the XG pure Dos drivers for that one, not sure I'll test it out later.

you clarified what i was trying to say too thanks 😀

Both the first and the second game from the 1995 Prince of Persia CD collection (Mobygames entry) work fine with IRQ 5. Not sure about the earlier floppy versions though.

Fair use/fair dealing exception

I do know of at least one game which is hardcoded to IRQ 7 - Gods from 1991. However, that one was made before the SBPro was released and IRQ 5 became the standard. From my understanding, such games are the exception, rather than the norm.

PC#1: Pentium MMX 166 / Soyo SY-5BT / S3 Trio64V+ / Voodoo1 / OPTi 82C930 / AWE64
PC#2: Celeron 466 / Abit ZM6 / Voodoo3 / AWE64 Gold / YMF744 / SC-155
PC#3: AthlonXP 1700+ / Abit KT7A / GeForce4 / SBLive / ALS100
PC#4: Athlon64 3700+ / DFI LanParty / 9600GT / X-Fi Titanium

I believe its the original floppy version is IRQ 7

Drivers for the SB Pro are not going to help you here, Prince of Persia uses its own internal driver to communicate with your cards. Except for a very few games, you do not need to install the drivers for the SB Pro in DOS, although the mixer control comes in handy.

If the game crashes right as it is playing the first digital sound effect, either you have an IRQ/DMA issue or a faulty card. Set your Pro to I/O 220, IRQ 7 and DMA 1. Make sure your SET BLASTER=A200 I7 D1 T4 is set in AUTOEXEC.BAT.

I tested it on a XG in pure DOS with the floppy version and confirmed this.
