Here follows a quick reference guide of the most useful API calls for cracking
with SoftICE. Note that the "A" after the API means 32 bit so if the program
you wanna crack is 32 bit put the "A" else don't.

Reading/Writing files:

ReadFile
WriteFile
CreateFileA

Reading data from INI file:

GetPrivateProfileStringA
GetPrivateProfileIntA
WritePrivateProfileStringA
WritePrivateProfileIntA

Registry Access:

RegCreateKeyA
RegDeleteKeyA
RegQueryValueA
RegCloseKeyA
RegOpenKeyA

DialogBoxes:

GetWindowTextA
GetDlgItemTextA
GetDlgItemInt

MessageBoxes:

MessageBox
MessageBoxA
MessageBoxExA
MessageBeep

Time And Date:

GetLocalTime
GetSystemTime
GetFileTime

Creating a window (like a NAG):

CreateWindowExA
ShowWindow

The following is not an API but it can intercept almost any kind of call
for getting a serial number:

Hmemcpy

And here follows a quick table with the most used ASM jump used in cracking
with their HEX code.

Hex:          Asm:      Means
75 or 0F85    jne       jump if not equal
74 or 0F84    je        jump if equal
EB            jmp       jump directly to
90            nop       no operation
77 or 0F87    ja        jump if above
0F86          jna       jump if not above
0F83          jae       jump if above or equal
0F82          jnae      jump if not above or equal
0F82          jb        jump if below
0F83          jnb       jump if not below
0F86          jbe       jump if below or equal
0F87          jnbe      jump if not below or equal
0F8F          jg        jump if greater
0F8E          jng       jump if not greater
0F8D          jge       jump if greater or equal
0F8C          jnge      jump if not greater or equal
0F8C          jl        jump if less
0F8D          jnl       jump if not less
0F8E          jle       jump if less or equal
0F8F          jnle      jump if not less or equal
