Some password decoding:
Each letter represents a hexadecimal character (0-F). The sequence if LOLOcode would be BCDGHJKLMPQRTVYZ. Adding 1 to the first byte and subtracting 1 from the second byte will tell you the password for the next level.

LOLOcode:
B C D G H J K L M P Q  R  T  V  Y  Z
Hexidecimal:
0 1 2 3 4 5 6 7 8 9 A  B  C  D  E  F
Decimal:
0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
If you would rather do arithmetic in decimal, here is a reminder on how to convert a two digit hexadecimal to decimal:
(16 × the left digit) + (1 × the right digit)
OxAA=(16×10)+(1×10)=170=QQ
And convert decimal (less than 256) to two digit hexadecimal:
Integer divide by 16 for the left digit. The remainder is the right digit.
170/16=10 and remainder 10=A and A=Q and Q

Here is an example of finding the password for level 8-1 if you have the password for 7-5:
(BCDGHJKLMPQRTVYZ)
DDYR
DD+1=DG = 0x22+01 = 34+1
YR-1=YQ = 0xDB-01 = 219-1
DGYQ

Here is an example of finding the password for level 5-3 if you have the password for 6-3:
CRZD
CR-5=CK = 0x1B-05 = 27-5
ZD+5=ZL = 0xF2+05 = 242+5
CKZL

The sequence starts at BBBV and ends at GCVT and does not extend in either direction.
