Apple II version with slightly edited levels

Post by David »

Today I found a version of PoP for the Apple II with slightly edited levels.
It was made by The Doppleganger.

Link: https://mirrors.apple2.org.za/apple.cab ... %20persia/
It's a *.shk (ShrinkIt) file which can be extracted with CiderPress.
I've attached a ZIP with the extracted disk image, and the two text files extracted from the disk image.
This disk image can be used in the same way as the disk image which comes with leapop.

The ABOUT.EDITION.TXT contains information about the changes.
The following parts are related to levels:

Code: Select all

    4. Re-designed some of the rooms in each level.
       (In Prince of Persia, the levels are divided into 24 rooms.  Some of the
       levels didn't use all 24, even though some were already designed.
       Anyway, I redid the room map and put some in where they could be found
       easily, and some where they couldn't be.  In the new rooms I often suck
       in super potions and such, so they would be worth going to (in some
       cases))

    5. After you kill Jaffar, and go through the exit door, you come to level
       13.  On the original it was only 5 rooms (out of the 24).  On this
       version it is 24 rooms with guards (so keep on guard)

Interesting find. (I've added it here.)

And for a quick hack to open and view the mod with leapop 0.9b, make the following 2 changes:
1. On line 872, set iDiskImageA to 0 instead of -1.
2. Change the arLevelOffsetsA[][15] offsets to:

Code: Select all

  {
    0x27200,
    0x27B00,
    0x26900,
    0x4F200,
    0x4FB00,
    0x4E000,
    0x4E900,
    0x4CE00,
    0x4D700,
    0x4BC00,
    0x4C500,
    0x4AA00,
    0x4B300,
    0x49800,
    0x4A100
  },
