-Conversion formulae between discs and versions of Resident Evil 2-
Written by Lazy Bastard
Resident Evil 2 came out with two discs: Leon's and Claire's. Then it was re-released as Resident Evil 2: Dual Shock, enabling the use of the Dual Shock controller. The memory addresses for everything in the game for any of these discs are different by a certain offset (except in the beginning of the memory, where there seems to be little difference until a certain point), in reference to the other disc in question. People used to constantly request for codes to be hacked by me that have already been hacked, just not for the disc they want them for. Well, I saw this as an irritating distraction, and eventually solved the conversion formula for RE2 Regular between discs. This led to a few other people (including floydfan) discovering the conversion formula for conversion between Dual Shock and Regular RE2, and my creating everything else that was missing. After all this, I decided that ALL the conversion formulae for any disc or version of RE2 should be put into one FAQ, so here it is. From now on, I will refer to the different versions simply as "Regular" or Dual Shock", "Claire's" or "Leon's". Remember that any changes made to a code to convert it are made only to the address portion (the first eight digits of the code...well, actually, the first two aren't really part of the address, but...just remember what I said before)
-OK, so what are the formulae?
For Regular; Leon to Claire: Subtract 00000238
For Regular; Claire to Leon: Add 00000238
For Dual Shock; Leon to Claire: Subtract 8C
For Dual Shock; Claire to Leon: Add 8C
From Regular; Claire to Dual Shock; Claire: Add 00008080
From Dual Shock; Claire to Regular; Claire: Subtract 00008080
From Regular; Leon to Dual Shock; Leon: Add 00007ED4
From Dual Shock; Leon to Regular; Leon: Subtract 00007ED4
From Regular; Claire to Dual Shock; Leon: Add 801C
From Dual Shock; Leon to Regular; Claire: Subtract 801C
From Regular; Leon to Dual Shock; Claire: Add 7E48
From Dual Shock; Claire to Regular; Leon: Subtract 7E48
Well, that's about it. No, wait, that's completely it. Hope these help you somehow. Remember that you are working in hex, which goes from 0 to F, F representing 15. If you need more help with hex, read the FAQ in the Hacking FAQs section of the GSHI on the basics of hexadecimal.
