Weird level sequence...

[Prince Of Apollia]

I am creating a new story based pop1 game, but for this to work, when I enter the end gate on lvl 13 I have to get to lvl 1, how is this possible. I can't find it on the custom pop page, anyone any ideas. For in case I have to code this in manually. How can I change prince.exe in to code and back to exe?

Thanks

Change these:

Code: Select all

83 3E 9E 0F 0D 74 23 83 3E 9E 0F 0F 74 1C B8 29 00 EB E5 FF 06 18 3D EB 11

->

Code: Select all

B8 29 00 EB F3 90 83 3E 18 3D 0D 75 06 C7 06 18 3D 00 00 FF 06 18 3D EB 11

and

Code: Select all

C6 06 22 3D B9 EB 20 79 03 0D 03

->

Code: Select all

C6 06 22 3D B9 EB 20 6C 03 0D 03

In exchange, Level 13 and 15 now have ending music.

I came up with my own hack before I saw the post by teljesnegyzet.

You need to hex-edit prince.exe.

I changed the code which decides which level to load after the potions level:

Code: Select all

In play_level():
seg003:0189 83 7E 06 10              cmp     [bp+level], 16
seg003:018D 75 0C                    jnz     loc_498B
seg003:018F A1 9E 00                 mov     ax, copyprot_level
seg003:0192 89 46 06                 mov     [bp+level], ax
seg003:0195 C7 06 9E 00 FF FF        mov     copyprot_level, 0FFFFh

Search: 83 7E 06 10 75 0C A1 9E 00
Change: 10 to 0E ("16" to "14")
Change: A1 9E 00 to B8 01 00 ("mov ax, copyprot_level" to "mov ax, 1")

Thanks, just how to I hex-edit prince.exe? Is there any tool for this on popot.org?

If you already use apoplexy, you can press F12 on its main screen.
If you prefer to use a stand-alone program, see the how-to for wxHexEditor.
