HEX CODE CHEATS FOR "ALONE IN THE DARK 2" -- PART 1
---------------------------------------------------
IMPORTANT NOTE: If you have downloaded a copy of the English version of AITD2 that 'freezes' when Carnby enters the sorceress' bedroom, or if you have downloaded a copy of the French version of AITD2 that 'freezes' when Grace climbs the ladder to go onto the deck of the pirate ship, you have a corrupted copy! I plan to try to correct these problems on my own, so that good copies will be available for download. Hopefully, I will have all the troubleshooting work completed sometime during the early months of 2007.
If anyone is trying to run AITD2 under MS-DOS 6.22, without success, send an e-mail and I will reply. I can provide sample AUTOEXEC.BAT and CONFIG.SYS files, as well as installation software for Creative Labs Soundblaster 16 plug-and-play and Vibra 16 legacy cards. I also have copies of the AITD2 copy protection cards that can be sent as a GIF file. You must be a registered Abandonia member in order to access the "Members" section of this website and to send e-mail to me. --- Methuselah
================================================== =
To use the hex code cheats, you must have a hex editor. I use, and recommend, XVI32 Hex Editor, by Christian Maas. Do a Google search to find a copy of this freeware editor. The file that must be edited is named SAVE0.ITD.
Hex addresses for health and inventory items in saved games each occupy two bytes; thus, for example, 68C4 goes with 68C5. The hexadecimal values must be written in lo-hi format; 12 0C becomes 0C 12, for example. To boost health points and ammo, first convert the decimal value to its hexadecimal value, then use the two lists immediately following to convert the hexadecimal value to its 'encrypted' value, then transpose the resulting two byte values (if the decimal value is over 255).
Note the following examples:
255 DECIMAL = FF HEX = CA CONVERTED (NO FORMAT CHANGE NEEDED)
24683 DECIMAL = 60 6B HEX = 55 5E CONVERTED = 5E 55 LO-HI FORMAT
32000 DECIMAL = 7D 00 HEX = 48 35 CONVERTED = 35 48 LO-HI FORMAT
So, to boost Carnby's health points to 255, enter CA in hex address 68C4. To get 32,000 health points, enter 35 in address 68C4; enter 48 in address 68C5.
================
CONVERSION LISTS
================
1. 2.
0 = 3 0 = 5
1 = 2 1 = 4
2 = 1 2 = 7
3 = 0 3 = 6
4 = 7 4 = 1
5 = 6 5 = 0
6 = 5 6 = 3
7 = 4 7 = 2
8 = B 8 = D
9 = A 9 = C
A = 9 A = F
B = 8 B = E
C = F C = 9
D = E D = 8
E = D E = B
F = C F = A
Only a few hex addresses need to be edited to get through the game easily. The most essential addresses are listed below for the English and French versions of the game.
=============================
ITEM FRENCH ENGLISH
=============================
HEALTH 5E38 68C4
REVOLVER 5E3A 68C6
THOMPSON 5E28 68B4
SHOTGUN 6192 6C1E
DERRINGER 5E70 68FC
GRACE ---- 694E
To avoid having health and ammo automatically reset to lower values, do not use health flasks, Thompson ammo magazines or shotgun shells that are found during the course of the game. Flasks, ammo magazines and shells can be picked-up, but they should not be used after hex addresses have been manually edited. Adhering to this rule will eliminate the need to edit additional hex addresses.
Supplementary hex addresses follow below (English version).
68C0 Thompson Ammo
68C2 Thompson Ammo
68B4 Thompson Ammo
6A7A Thompson Ammo
6960 Pirate Pistol
6962 Pirate Pistol
6A7E Pirate Pistol Ammo
6A80 Pirate Pistol Ammo
695E Pirate Pistol Ammo
