Game File Bug Fixes and Exploits

Game File Bug Fixes

Cash Rollover Bug Fix

If you have so much money that it all of a sudden it becomes negative (eg: $-2,168,000,000), you can delete the LIGLOB.DAT file and replace it from a new savegame. You cash becomes approx $4mil which is what is available from the new game. Your income will be preserved but the financial graph data will be trashed.

Alternatively you can use a hex editor (see Game_Editors#Hex_editors or HackerTools). Navigate to the fourth byte of the LIGLOB.DAT file and change its value to something between 0 and 127 (00 to 7Fh hex). 64 (40h) is recommended, giving you about a billion. This solution has the advantage of leaving all the other data in the savegame intact.

Research Bug Fix

If your research progress has become corrupted due to the bugs in the research tree of TFTD, replace the RESEARCH.DAT, UP.DAT, PROJECT.DAT, PRODUCT.DAT, BPROD.DAT with files from a new saved game if you don't want to use a hex-editor.

Game File Exploits

Bottomless Money Pit

Insert a LIGLOB.DAT file from an old game that has lots of money, into a new game. You will inherit the cash balance of the old game. Or you can copy the file from a new savegame, in which case your cash becomes approx $4mil (the amount available at the start of a new game).

Enlightened Xcom

The Research Bug Fix (above) can be abused by inserting old files from a completed game into the save folder of a new game. The files to insert are UP.DAT, RESEARCH.DAT, FACIL.DAT and PRODUCT.DAT. You can (optionally) also copy SOLDIER.DAT to transfer you old soldiers into the save as well, just be sure the number of new soldiers is equal to the number of old soldiers you are transferring from your old game or the game will crash. SOLDIER.DAT also stores the solders' equipped armour (not their inventory though, unfortunately): if you remove all their armour then then copy the SOLDIER.DAT from your old game again, you can effectively duplicate said armour.

+Alternatively you can use a hex editor (see [[Game_Editors#Hex_editors]] or [[HackerTools]]). Navigate to the fourth byte of the [[LIGLOB.DAT]] file and change its value to something between 0 and 127 (00 to 7Fh hex). 64 (40h) is recommended, giving you about a billion. This solution has the advantage of leaving all the other data in the savegame intact.
-* If you insert LOC.DAT, CRAFT.DAT and BASE.DAT from an old savegame into a new savegame folder, you'll have your previous base(s), previous craft, and previous alien base(s).
-<br>NOTE: If you plan on overwriting the new with old, you must remove the soldiers from any and all transport craft before you copy the files over to the new savegame folder. Doing so will stop any 'ghost' soldiers remaining on the transport craft when you go to equip it. Alternatively, you can copy the SOLDIER.DAT file from the old location.
-===Why Do This?===
-When you copy LOC, CRAFT, and BASE files to a fresh new game savegame folder, you'll have all the alien bases from the old game present in a new game. Doing this lets you play a game where the aliens already own the earth and you have an uphill battle to get earth back.
-===Setup===
-To get +20 alien bases onto the surface of earth, you have to edit some things to make the gameplay go alot faster. You don't want to play the game through properly. Forget research and manufacturing, training etc. Using a savegame editor, you'd want to:
-* give yourself 200mil. and build seven more bases spread around the globe.
-* edit the layouts of the eight bases to contain hangers, stores, detection, alien fuel, hand weapons, armour etc.
-* buy 6 fighter craft then use an editor to change all craft to Avenger/Leviathan and give them plasma/sonic weapons.
-* use an editor to change hitpoints of ALL alien craft to 25, and speed to 1000. Change xcom craft to 1000 hitpoints and 10000 speed and 500 fuel. It may help to decrease the weapon range of some of the UFO/USO.
-* buy 10 soldiers for each base and change their states to 100 (or thereabouts)
-* edit diplomacy so that you get 100mil per month. It will adjust naturally thereafter.
-===Fast Gameplay===
-The only way to play this game is to shoot and destroy (not crash land) the alien craft. Since the hitpoints of a Battleship/Dreadnaught is only 25, it will take one shot from the xcom craft to blow it up. Also:
-* if you have a UFO on a mission to scout for an alien base location, don't shoot it down. Let it go and you'll have a base building squadron appear earlier. Look for the alien base once you think its built and then you can go after the squadron.
-* if you have an alien craft looking for your base, let it go until you have the VERY LARGE types appear. Shoot these down for big score bonuses.
-* you are playing the game for a positive score at the end of the month. Large and Very Large ufos give the biggest scores when destroyed. You can ignore the rest. For the reason the more you shoot down the more you'll have to deal with retaliation missions later on. The objective is to survive until the next month and letting aliens build bases. You can ignore terror sites as well if your score permits this.
-===Over 20 Alien Bases===
-Once you have over 20 alien bases (and under 25), go thru and sack everyone except 8 soldiers at your first base. These eight soldiers are your defending force if you miss an alien craft attacking you first base. They are not necessary, but just in case. Once you have seven undefended bases, remove the Mind/MC Shield and let the aliens destroy these bases. You might have to shoot down many more alien craft before the aliens start getting annoyed. Once you have one base left, remove the soldiers from any transport crafts and save your game and exit. Use an editor to change the craft back to terran types and replace the weapons with the default starting weapons (stingrayX6,avalanchX3 or ajaxX6,DUPX3).
-<br> Cut CRAFT.DAT, LOC.DAT, and BASE.DAT from the savegame folder and then make a copy of these files as a backup.
-===Using the Files===
-Start a new game and plonk your first base down anywhere. Remove the eight agents assigned to the tranport craft in this new game, then save and exit. Copy the three files into this savegame folder.
-<br>Note: It may help to make new install of the game because you have edited the previous installation, unless you want to go thru the old install and revert the editing.
-<br> This new game from the very start has now got 20+ aliens bases scattered over the globe. Enjoy your (short) time as an Xcom Commander.
+===Research Bug Fix===
+If your research progress has become corrupted due to the bugs in the research tree of TFTD, replace the [[RESEARCH.DAT]], [[UP.DAT]], [[PROJECT.DAT]], [[PRODUCT.DAT]], [[BPROD.DAT]] with files from a new saved game if you don't want to use a hex-editor.
