Hi dear Prince of Persia Fans,
It's so nice to see that there are many active players in this forum. I believe there are also many veterans here who could help me about my situation.
As another PoP fan, I'm happy to say that I have all PoP games as original discs/floppies (even PoP2). Recently I bought Prince of Persia 1 (PC-UK version) as 3.5" and 5.25" double pack. I felt extremely happy and lucky to find this vintage in 2015! It was my only missing part of my PoP collection. But... whatever I do, I couldn't make these floppies work. Neither 3.5" single floppy, nor 5.25" two floppies.
Normally, for my original floppy games, I use a program called "WinImage" to create their backup file in .vfd or .img format. This way, I keep every details and datas in the floppy (even the floppy label and boot sector properties). So, I wonder, are there collectors here, who have made backups of their original PoP1 floppies just like I do (or any similar way)? I would be very happy if you share them with me.
Any help will be appreciated. Thank you

Various images in .ima format can be found here.
Re: Prince of Persia 1 Original Floppy Images
OMG that's awesome! I don't know how to thank you and the others who've uploaded those images. They all are just like how I wanted and none of them seems modded, great!
I checked v1.0, 1.1 and 1.3 -- Mine seems v1.1, because only v1.1's copy protection accepts the characters in my booklet. I think that's enough to make sure about this.
I just wonder, do the contents of the disks of UK and US versions exactly the same? For example, UK versions are released by Domark Software. May there be any note in the game or in setup/install windows about Domark?

Re: Prince of Persia 1 Original Floppy Images
Hi again, today I did read the 5.25" disks of my UK version 1.1 floppies. But it seems WinImage cannot handle these 5.25" disks. When I click "Read disk" in both disks, it says "Disk error no 65535 on track 0, head 0". I know there is no problem in the disks because I could copy the files manually without WinImage. Any idea how to make image of them via WinImage? I need to check their boot sectors. And as I know, only way to do it is making image with WinImage.

You could try some other disk-image software.tez wrote:But it seems WinImage cannot handle these 5.25" disks.

Re: Prince of Persia 1 Original Floppy Images
Thanks for assistance. I used some better devices and finally could read my floppies. All 3 disks work like a charm, and I want to share their ".vfd" images with other PoP fans here.
Just reminding again, these images are from original UK/EU release v1.1 by Broderbund and Domark (1989/1990). Disk contents are "almost" the same as US v1.1 release. As I see, file sizes are the same, but times are not. Also, the disk labels which are "PRINCE" in US version, while mine are "SIR PRINCE"
Enjoy

Re: Prince of Persia 1 Original Floppy Images
Your 3.5 image is similar to the one on PoPUW: http://popuw.com/download.html
The difference is that in PoPUW's (The Hit Squad) version:
* PRINCE.EXE was changed (hacked), see below,
* PRINCE.EXE and INSTALL.EXE were renamed to PRINCE1.EXE and INSTALL1.EXE,
* there are two extra files: PRINCE.BAT and INSTALL.BAT.
The differences in PRINCE.EXE are:
(Note that these are parts of the 1.0 disassembly, but the relevant parts of the code are the same.)
Change: 75->EB, that is: jnz->jmp
Effect: Skip the potions message.
Change: 74 03 -> EB 0F, that is: jz loc_B621 -> jmp loc_B62D
Effect: All potions on level 15 become open potions.
These explain the oddities that Andrew noticed here: viewtopic.php?p=8207#p8207

Re: Prince of Persia 1 Original Floppy Images
My set looks like exactly the same as this photo, which I found on internet.
It seems my version doesn't have music. Or I just couldn't configure, I'm not sure. Is there any way to enable it?
Also, I couldn't get work the "install.exe" properly. It opens but doesnt install anything. I tried on Win98 and Win7 (via DosBox). Do you know what problem is?

I think it's this problem: viewtopic.php?p=14201#p14201tez wrote:Also, I couldn't get work the "install.exe" properly. It opens but doesnt install anything. I tried on Win98 and Win7 (via DosBox). Do you know what problem is?
This might happen if the cycles value (in DOSBox) is too high. Try with cycles=3000.tez wrote:It seems my version doesn't have music. Or I just couldn't configure, I'm not sure. Is there any way to enable it?
