To cheat on the PC version of Rick 2 using hex codes, the first thing you'll need is a hex editor. Many of these are available as freeware, such as XVI32, which will do the job fine.
Make a copy of MAIN.EXE (let's call it HACKED.EXE) and open it with XVI32, and you'll see this screen:
The table of hex codes can now be edited. Each line has 16 hex codes in it, corresponding to one byte, with the address shown at the side. For instance, the first line:
00000000h: 4D 5A 7C 01 6C 00 1E 00 20 00 00 00 FF FF 00 00
This means the byte with address 00000000h has the value 4D, 00000001h has value 5A, etc. The "h" is a suffix added to denote the number is hexadecimal.
Take another look at the cheat for infinite lives:
|ADDRESS||OLD CODE||NEW CODE|
|00006ADFh||FF 0E 14 66||90 90 90 90|
What this means is, the value FF at address 00006ADFh needs to be replaced with 90, as do the following three bytes (i.e. 00006AE0h to 00006AE2h). Scroll down to line 00006AD0h:
Sure enough, the values at addresses 00006ADFh to 00006AE2h are FF, 0E, 14, 66.
Change all these to 90, save the file, run it, and Rick will never die.
The same applies to all the other cheats given on the previous page.
