Zombieville (1997)/Debug Text

This is a sub-page of Zombieville (1997).

When viewing ZOMB.EXE in a hex editor, there's a lot of interesting details buried inside. For example, there seems to be duplicated strings from the ZOMB.PRF file inside the executable and plenty of strings for different purposes.

MISC STRINGS

Under these following addresses in ZOMB.EXE, there seems to be an assortment of miscellaneous strings.

Address	String	Comment
0x00096E04	-Too much to list-	There seems to be game instructions in English.
0x00097400	"No! Don't Peek"	No idea why this is here...
0x00097530	"Monster.Armed..Monster...." and more...	It appears to be Debug Functions of some sort?
0x000978B5	"Next to Bugger"	These handful of strings are about restoring Matt's Health.
0x00097931	"Blunderbuss"	There is no such shotgun in the game. The next "shotgun" references are possibly to help calculate pellet damages.
0x00097A00	"Crow bar wrapped around the cranium"	No idea what this means.
0x00097A68	"Girly Punch"	Possibly refers to zombie melee attacks or a 'sissy' punch animation.
0x00097DA2	"Colt Pistol"	String to show on top left when picking up guns and checking guns' ammos. However, this gun isn't found anywhere ingame, let alone its ammo.
0x00097E1D	"M16 + Granade Launcher"	Same as Colt Pistol, but with a misspelling bonus.
0x00097E54	"Revolver"	Unknown if intended to be an useable gun or merely an inventory item.
0x00097EAC	"Chainsaw"	Unknown if intended to be a useable melee weapon but left as work in progress or merely an inventory item.
0x00097EB8	"Cleaver"	Same as from Chainsaw.
0x000980EC	"Smoke Grenade"	Unknown if the M16 w/Grenade Launcher would be able to fire different rounds or Matt would use them in a different scenario.

DEBUG STRINGS

Under the following addresses in ZOMB.EXE, there seems to be strings meant for a debug menu. It is currently unknown if the debug menu is a remnant of development and is inaccessible, or it is functional but currently there are no known ways to access it.

Address	String	Comment
0x000989B4	"Bedlam Ground Floor"	These handful of strings seem to show all locations in Zombieville.

0x000989D8	"Bedlam First Floor"
0x000989EC	"Town Square"

0x00098A38	"Garage"

0x00098A8C	"Pumphouse interior"

0x00098B14	"Chapel"
0x00098B1C	"I want to stare at the title Page"	Do you?

INHOUSE LEVEL EDITOR STRINGS?

For the next handful of strings, it appears to be for an inhouse level editor?

Address	String
0x00098B40	"Percentage Chance of Anim Running"
0x00098B65	"Should this Animation be forced?"
0x00098B88	"Do you want to alter/create NPC end Pos?"
0x00098B88	"Does this ammo hurt characters when fired"

.ZLD FILES

In all of the LEVELDAT folders, files with .ZLD extension at this address "4E 6F 21 20 44 6F 6E 74 00 09 50 65 65 6B" contains the following string: "No! Don't..Peek"

It is unsure if this was a little developer comment to dataminers to plea to not look inside these specific files.

ZOMB.PRF

According to the developers [that will remain anonymous], this ZOMB.PRF file was NOT intended to be shipped with the game and served as for debugging purposes.

It also gives an insight to developers' frustrations at the time, which folks can now appreciate their efforts of developing Zombiville.

NOTE: This file can be opened with NotePad++, numbers on the middle are times that the game called each function. The numbers on the far left are believed to be size in bytes that the function processed.
