- ---- FEARS doom-clone Passwords explanation by Giovanni Meroni --------
-
- When I solved the first level and I got the level code for the second level I
- saw that this code was a 8 digit hexadecimal number but I thougth that this was
- meaningless and the code was only a casual sequence of digits...
- No! That's wrong!!! In the level code is coded (well is a code after all...:-))
- all the important stats of the player: His number of lives, ammo, level and the
- type of weapons.
- Infact try to end the first level many times, with different number of ammo or
- lifes, you'll get a different code for the second level...
- Note that these codes don't remember things like energy, treasures founds, time
- used, secrets founds, so when you enter a level using a code all this stats will
- be at a default level.
- After collecting some Level 2 access code I started to try to understand how all
- these informations are coded.
- First of all I discovered that the 8 digit sequence has to be seen as the union
- of two 4 digit numbers: In the first one are coded the level, the number of
- lives and the type of weapons available, and in the second one the number of the
- two type of ammo.
- Exemplation:
- lv code F8F856A5
- \__/\__/
- \ \__ means 99 weapon of type 1 and 28 of type 2
- \_____ means access to level 2 with gun and 0 lives left
-
- lv code C9F545B9
- \__/\__/
- \ \__ means 53 weapon of type 1 and 14 of type 2
- \_____ means access to level 3 with gun and machinegun
- and 3 lives left
-
- N.B: the two groups of digits are completley scorrelated!!! so you can always
- get the first 4 digit from a level code and the last 4 of another one and
- you'll have another valid level code!!!
- example: using the two code above you can buld up two other codes:
- F8F845B9 and C9F556A5 , and those are valid codes too!!
-
- So...

- | Explanation of the SECOND group of a level code ( the last 4 digits) |
- ------------------------------------------------------------------------
- (My GrandFather always told me to start at the beginning ;-) )
- Well... I had no luck and so there is NO explanation :(
- but I collected a few codes so here they are:
- ___________________________
- | Lv code | type1 | type2 | Type1 means the number of ammunitions of
- +---------+-------+-------+ type 1 ( gun and machinegun ammo)
- | 54AD | 99 | 14 |
- | 94AC | 98 | 14 | Type2 means the number of ammunitions of
- | 40A8 | 00 | 14 | (guess ?) type 2 ...( Rockets )
- | 91ED | 91 | 14 |
- | 519D | 87 | 10 |
- | 5000 | 64 | 00 |
- | 45B9 | 53 | 14 |
- | 56A5 | 99 | 28 |
- | 5C8D | 99 | 42 |
- | 5E85 | 99 | 56 |
- | 742D | 99 | 70 |
- | 7625 | 99 | 84 |
- | 7C0D | 99 | 98 |
- | BC0F | 99 | 99 |
- +---------+-------+-------+
-
- When I foud out BC0F I stop searching new codes because it'd be pointless:
- BC0F is the best code to use to start every level with the max ammo and so...
- I often use it...
-
- If you manage to find out how ammo numbers are coded into this 4 digit well...
- DONT let me know!!!! ;-) I really don't care much adout it....
-
-
- Well now ....
- ------------------------------------------------------------------------
- | Explanation of the FIRST group of a level code ( the first 4 digits) |
- ------------------------------------------------------------------------
-
- Here the thing is a bit tricky : It envolves the use of Binary to Hexadecimal
- conversions and so if you dont know much about it... Jump to the conclusions ;-)
-
- In the first 4 digits are coded the level number, the type of weapons and the
- number of lives.
-
- The code number is a Hexadecimal number, so it can be written in binary:
-
- D8F5 -> 1101 1000 1111 0101
-
- and the meanings of each group of bit is:
-
- xxxx 100x x11x xxxx
- \__/ \____/ \__/|\_ =1 if you have the machinegun (0 else)
- \ \ \ \__ =1 if you have the rocket launcher (0 else)
- \ \ \____ in this triplet is coded the level :
- \ \ 111 = level 1 110 = level 2 101 = level 3
- \ \ 100 = level 4 011 = level 5
- \ \_________ this is a sort of checksum to see if the code is valid:
- \ I had not foud out how this works but you can try
- \ some combinations and use the only one that works
- \___________ in these bits is coded the number of lives you have:
- 1111 = 0 lives
- 1110 = 1 life
- 1101 = 2 lives
- 1100 = 3 lives
- ..... .......
- 0111 = 8 lives
- 0110 = 9 lives
-
- Here are some codes I found out: I calculated them first and then I tried to
- insert them as password in the game and they all worked well
-
- | Level | only Gun | Gun+Machinegun | gun+Machinegun+ |
- | | | | rocket launcher |
- +-------+-----------+----------------+-----------------+
- | 1 | | | 6D7F | 9 LIVES
- +-------+-----------+----------------+-----------------+
- | 2 | F8F8 | F879 | | 0 LIVES
- | | E878 | E8F9 | | 1 LIFE
- | | D9F8 | D979 | (*) | 2 LIVES
- | | C978 | C9F9 | | 3 LIVES
- | | BAF8 | BA79 | | 4 LIVES
- (*) ....
- | | (*) | 7C79 | | 8 LIVES
- | | | 6CF9 | 6DFB | 9 LIVES
- +-------+-----------+----------------+-----------------+
- | 3 | F974 | F875 | | 0 LIVES
- | | E9F4 | E8F5 | | 1 LIFE
- | | D874 | D975 | (*) | 2 LIVES
- | | C8F4 | C9F5 | | 3 LIVES
- ....
- | | (*) | (*) | 6C77 | 9 LIVES
- +-------+-----------+----------------+-----------------+
- | 4 | | F971 | F873 | 0 LIVES
- | | | E9F1 | E8F3 | 1 LIFE
- | | | D871 | D973 | 2 LIVES
- | | | C8F1 | C9F3 | 3 LIVES
- | | | | BA73 | 4 LIVES
- | | (*) | (*) | AAF3 | 5 LIVES
- | | | | 9B73 | 6 LIVES
- | | | | 8BF3 | 7 LIVES
- | | | | 7C73 | 8 LIVES
- | | | | 6CF3 | 9 LIVES
- +-------+-----------+----------------+-----------------+
- | 5 | | | FBEF | 0 LIVES
- | | | | EB6F | 1 LIFE
- | | | | DAEF | 2 LIVES
- | | | | CA6F | 3 LIVES
- | | | | B9EF | 4 LIVES
- | | (*) | (*) | A96F | 5 LIVES
- | | | | 98EF | 6 LIVES
- | | | | 886F | 7 LIVES
- | | | | 7FEF | 8 LIVES
- | | | | 6F6F | 9 LIVES
- +-------+-----------+----------------+-----------------+
-
- (*)I Have no code for this combinations of level,lifes,weapon_type because
- I have no time to spare on this silly things :) (And, most important fact,
- finding out new codes is really boring, when you know how to do it)
- If You really need them (I cant immagine why), Well found them out yourself!!
-
- -----------------
- | CONCLUSIONS | (The most waited part......)
- -----------------
-
- The complete codes to start a level with all ammo, all weapons, 9 lives are:
-
- level1: 6D7FBC0F
- level2: 6DFBBC0F
- level3: 6C77BC0F
- level4: 6CF3BC0F
- level5: 6F6FBC0F
-
-
- *++++++++Ending note....
- - Forgive my Spagetti-English... but I'm a Spaghetti-eater (i.e an Italian boy)
- - All these codes works well on my version of FEARS, but in the building of the
- codes there is room to have a different set of codes for different copy of the
- game.. If it'd happen, these codes won't work (obviously) but I think that the
- logic behind won't change.Try to change the '100' part in the checksum nibble,
- or the '11' bits between checksum and level nibble.
- - Let me know your opinions on this.
- - You can use this doc and the informations inside it as you want, but dont
- steal the credits !!!
