TREE9 tree, last leaf falls, the end
PoP1: prince.exe megahit x
PoP2: prince.exe yippeeyahoo levelx
where x is the level you want to start
note: in pop2's beta versions change yippeeyahoo to makinit or makinit2
in pop1 1.3 and 1.4 change megahit to improved
start at another level than the first one
Note that support for non-vga screen modes (cga, herc, ega, tga) has been removed in version 1.4, so they'll only work in previous versions. Also, the set of allowed sound cards is different in each version.
About prince 2: Note that gameplay doesn't randomize the starting location, but uses a different built-in level-set.
If you type in to the start on some of those cutscenes, the cutscene is just repeated.
Using REC 2.0 - Reverse Engineering Compiler, you can sort the detected strings of the game (prince.exe); some of those are interesting, like: Printer error., Printer out of paper., etc.
The printer error messages are strange, because this game doesn't print anything.
ABOUT SAYCHEESE
If you type SAYCHEESE after the cheat parameter, you'll be able to view other rooms by pressing the arrow keys!
But: this prevents you from normal playing (or you have to use the W-E-R-S-D-F-X-C-V or U-I-O-J-K-L-M-,-. keys to move) and it's very buggy!
In level 11 (second red level) you can make one birdman killing an other!
Video link: http://www.sendspace.com/file/5t59hs
Notice that when the birdman kills the other, the prince's hitpoints are decreasing!
The game (so the birdman) thinks that the birdman is the prince, and this makes a bigger glitch: you can control a guard!
Start like this: PRINCE.EXE MEGAHIT/YIPPEEYAHOO LEVEL11 SAYCHEESE
and press left, up, up, up, up, left, left, up, down, up, down, K.
One birdman stays alive. You can control him: Ctrl=use sword, S or J=go left, F or L=go right, C=flip, M or X=turn left, V=turn right
Also, in level 1 itself with the SAYCHEESE parameter you can get guards to kill each other or 'become' a guard and control him as if he were the Prince!
WATCHMEM
Another parameter (although it's not very interesting): if you use the WATCHMEM parameter, the game will save a DUMPx.TXT automatically when you start the intro or start playing.
You have to call WATCHMEM with YIPPEEYAHOO or else it doesn't work. Also, the DumpX.txt files can be created with Alt+D in cheat mode too. The cheat mode DumpX.txt files though have the message: "Called via program cheat key." and the WATCHMEM DumpX.txt files have the message: "At beginning of ResetGame() loop."
Notes
GamePlay crashes the Demos with the following error:
ERROR: Couldn't find shape list.
Id = 3500
Because the PRINCE.DAT of the demo contains only the original level 1.
Sunshine doesn't activate cheats for PoP 2 Demo (1.0 or 1.1), but the cheat parameter is required for some parameters, for example LEVELn.
In the demo versionss: NISn and TREEn exit with an error message, LEVEL1 starts level 1, LEVEL2 exits with an error message, LEVEL3-LEVEL14 show a strange copy protection screen and then exit with an error message. The copy protection screen is all messed up, no images are shown but the selection rectangle is there. Weird, huh? Guess they created the whole game and then just removed huge chunks of code to leave behind the first level, and finally tacked on the ending message.
