Running Without the CD
7 March 2002

Daggerfall can be run without the CD to improve game speed and prevent the annoyance of having to switch CDs when playing various games.

  1. Install the game with the largest install size.
  2. Copy all the files from the DAGGER/ARENA2 directory on the CD to the ARENA2 directory on your hard drive where you installed the game. There are some large files which are not installed by the largest install size.
  3. Install the latest patch as desired.
  4. Edit the Z.CFG file in your Daggerfall directory. Change the PATHCD value to match that of the PATH value.
  5. To run the game don't use DAGGER.EXE as you would normally, but instead run the command FALL.EXE Z.CFG. You can create a batch file to prevent having to type it each time, but don't name it DAGGER.BAT.
  6. Some say you need to add the line set dos4gvm=@dagger.vmc to your Autoexec or your custom batch file, though the game will run without it.

Becoming a Lich
30 May 1998

I thought I'd put a slight new twist in the game and try to become a lich. This would be essentially similar to a vampire with a few differences. The first step is, of course, to become a vampire as one normally would. Once that has been accompished you'll need to edit several files.

  1. Change your face into that of a lich. Vampire faces are contained in the file VAMP00i0.CIF. I've created a skeleton like face which is available on the Daggerfall Graphics Page which will work fine. You will need to use Andypic and play with the X and Y position of the picture to get it right. Probably the easier way is to extract your vampire face and load it up into an editor. Copy the skeleton face into it and shift it until the eyes match up. Feel free to create your own 'lich' face, I'd love to see it.
  2. Change your body into that of a lich. I've created a semi-decent skeleton also available on the Daggerfall Graphics Page. Find your body image which can be found in the BODY0?i?.IMG files. You will probably need to change the size and position of the image a bit to match depending on your race. The skeleton was made for a male Redguard. It doesn't fit everthing 100% since everything is much skinnier than normal so you'll have to wear things to cover it up....of course you'll have to wear things anyways otherwise people would be fleeing in terror.
  3. Edit your savegame to make yourself immune to poison and disease. Your undead now and can't be affected by either. Also make yourself resistant to shock since this has a lesser effect on you.
  4. Give yourself a critical weakness to fire...very deadly to undead. Also give yourself low tolerance to cold (wouldn't want those bones to shatter now would we). Any previous weaknesses/resistances etc... other than those mentioned can be left as is.
  5. Give yourself a bonus to hit undead. Since you are one of the more powerful undead yourself, you have 'insight' or power over the other beings. Give yourself a phobia of humans since they generally want to kill you in nasty ways.
  6. In order for your reputation not to drop (you are a walking skeleton after all), you must do several things. First, ensure that you are covered as much as possible from head to toe at all times. Next, to futhur ensure people don't recognize you for who you really are, make a magical item to 'disguise' your looks. It can be any magical item really, just make it give it powerful enchantments including the soul of a lich. It probably should have a spell that is cast at all times although I find this annoying, I'll leave it up to you.

That is it really, not too much different than a vampire, but your character portrait is now real cool. Feel free to make comments or suggestions on this.

Changing the Wagon Weight Limit
30 May 1998

Changing the size of the wagon is simple, once you know the location of the bytes. In version 2.13 of Daggerfall the offset is 0xDFE13. Note that you must multiply the desired max weight by four when changing it (ie, a max weight of 1000 lbs is the hex code A00F). The max value for the weight is most likely in the area of 16000 lbs. To change the text that goes along with this, check out the offset 0x1B06AC, making sure not to exceed the length of the string that is there. If you don't want to do this hex-editting yourself, check out the utility DFWAGON.ZIP which allows you to change the value and the text string.

Repairing with Hex Editing
November 1996

I can't find my write up so here it is again. Pardon me if I cover points you already know. If you need a hex editor, I recommend Hex Workshop, which I got off the net from a Excite search (+hex +editor +win95). Remember it's always a good idea to backup the file first (HW will prompt you to do a backup if make changes).

The save games are in the Dagger directory under subdirectories SAVE0 through SAVE5 in the following order according to the save screen....

The save game file is savetree.dat.

The "name" of the save game is in a file called savename.txt if you want to verify that you have the right save.

Look for the item you want to repair (like %it of Orc Strength or Leaping %it), your items will generally follow your name and class name. Locate the beginning of the name then count forward 44 bytes. Position 44-45 are current status and 46-47 are max status. I generally set these 4 bytes to FF7F FF7F. This gives 32000+ uses before breakage. To help insure you are in the right place, for magic items, the two bytes right before that (42-43) usually start with a 2 (2###).

This works for ALL item, not just magical ones. One of these days, I'll play with those other two bytes and see if I can't figure out how to MAKE magic items ;-)

Fixing the Daedric Cuirass Bug + 'Repairing' Items
November 1996

Someone asked if you could use a hex editor to fix the broken Daedric Cuirasses and occasionally broken Daedric Greaves that the shops sell or that you find on monsters. Yes. In your hex editor find the beginning of the word Cuirass. In the file SAVETREE.DAT from your SAVEn directory Words 44, 45, 46 and 47 offset from the C in Cuirass will be something like 00H 80H 00H 80H. These two 2-byte hex words are "hits remaining" and "max hits" for the Cuirass. When it's new they should match. Once it's taken damage the hits remaining is reduced by the amount of the damage. Unfortunately, the word 8000H when taken as a signed integer is negative and the program believes anything that has a negative value is broken. Therefore the cuirass is broken, even though it's new. So, to make the new Cuirass not broken, change the values to FFH 7FH FFH 7FH for the words offset by 44, 45, 46 and 47 respectively. (This is reducing the max hits for the Cuirass from 32768 to 32767.)

You can also use this information to "fix" magic items (just use a hex editor to ake the two hex words match) until Bethesda fixes the "repairs objects" magic enchantment so that it works in the patched versions.

Be sure to make a backup of SAVETREE.DAT before messing with it. NOTE: This is fixed in patch v1.79.

Changing Item Materials
23 November 1998

Ok, so you're at bytes 44 or so doing "self repairs" on your magic weapons and armor, right? Well, you get to thinking about how ugly that leather cuirass looks. You decide to change it. So, you go down from the 44th "repair byte" to byte 50. This controls the style of the armor. You have to experiment to find out which is which, but if you go too high or too low, your armor disappears. Keep that in mind. Anyway, so you change it to look like that cool breastplate. But then you think, "wait... wouldn't it look better as, DAEDRIC?" sure it would! So, you move over 4 bytes to a 0#. Change this to a 09 (these numbers actually coorospond to the ones on the biog*.* edit list, cool huh?). Now, this WON'T change the color. So if you like the ebony color better than the daedric, hop over two more bytes (all this is to the right btw). Here you'll see a 1#. change this to a 17 (this matches the color of the type of material, aka 19 for daedric, 18 for orc, etc). Well, that's it. Have fun with that daedric!

	Bytes 44-47: Repair Bytes
	Byte 50: Armor Style (Leather, Plate, etc...)
	Byte 54: Armor Type (Steel, Silver, Daedric etc...)
	Byte 56: Armor Colour

Somthing to add to Changing Item Material Via Hex-editing In addition to the offset from Start of Item Name,

	Byte 57 - Item Weight (Weight = Byte value X 0.25 lbs)
These Byte modifications are only Valid with Plate armor and do not work with Chain/Leather armor. Other artifact characteristics (Net worth, embedded magic) are not effected by the byte change, so if you modify a cheap iron dagger into a feather weight Daedric Dagger, its selling price is still only as a cheap iron dagger.

One important thing to note: byte 54 is the Armor Material, and byte 55 is the armor TYPE. 0 is leather, 1 is chain, 2 is plate. I believe 3 is Crystal, 4 is Glass, and 5 and up are weird things like "of Lightning" and the like. Values past 2 add obscene amounts to your armor rating - like +58, or +2470. Of course, there is a maximum practical value, beyond which the game seems to ignore any further armor ratings. (This could simply be like the AD&D 'natural 20' rule, where a certain percent-score on the to-hit check results in an automatic hit, regardless of defenders' AC.)

Fixing the Negative Spell Point Bug
November 1996

This is a bug - nobody anticipated it because you shouldn't be able to select both low magic ability and no magic in daylight at the same time. What happens is that the "No Magic" part reduces your spellpoints to zero, then the low magic tries to further reduce that. Result is you have -32768 SP.

If you have a hex-editor, you can fix it. Use the editor to find your character's name in the savetree.dat file. Then count 565 bytes toward the end of the file from the first letter in your character's name - this byte should have a value of X3 where X is:

	0 if you have 3X Int in SP
	1 if you have 1X Int in SP  (SP = Int)
	2 if you have 2X Int in SP
	4 if you have 1.75X Int in SP
The 3 is because you selected both no magic and low magic. Change the 3 to a zero if you don't want either of these limitations. Make it 1 for no magic in daylight or 2 for low magic in daylight (or just make the whole byte zero - that gives you 3X INT in SP and no magic handicaps).

Monster Reflex Byte Location
November 1996

The monster reflex byte is location 130 bytes (82 bytes HEX) from the beginning of the character's name in the file SAVETREE.DAT found in the save game directories. The byte values range from 0 (Highest) to 4(Lowest). Alternatively you can download a program to do this automatically from the Files Area if you aren't familiar with hex editted binary files.

Increasing View Distance
3 January 1997

The first thing that really got on my nerves when I ventured into the wonderful world of Tamriel, was the limited view. I figured I had to fix that particular "bug". In the file savetree.dat, Daggerfall stores the sound/music/detail settings as vars. Now, the program itself does not allow you to enlarge the red bar beyond the limits of clicking-area, but a simple hex-editor does, if you only manage to locate the vars. As the size differs slightly from time to time, one cannot use the same offset for every savefile. To find the vars, just max the bars, save, let your hex-editor search the savetree.dat for these hex-values 7F,7F,00,7F,00 (the first byte being the detail, you may have to search for 7E's instead), and change the detail to FF!!!! When you load your game, you'll notice that your range has been doubled making everything look much better! (Not as good as unlimited range, but beats the hell out of the first one :))

Changing into Monsters
12 September 1997

Dunno if this would be in everyone's game. As I've said before, I hack considerably at my .exe [which I'd release if Bethesda would let me, cause I'm playin' a different game now. The 'Collectors' version, per se. (I've over 550 different items on my ship, as well as 150+ different paintings.)], but in my game, if one gets hit in at range while having The Wabbajack equipped, you are polymorphed into some other creature. I've screenshots of me being a rat, a lich and something else. Sometimes (often) when you go to view your character on the stats screen, it'll crash, which makes be beleive I didn't miss something when I was reading about the artifacts. It's interesting, because it TOTALLY skews your stats, and it RESETS the character. I don't know if any of these mutants would be playable due to stability.
