Extracting PkMn Red Blue from the 2 in 1 unl game
« on: July 23, 2017, 07:10:28 pm »
I am not sure if this should be posted here or in another thread, so if this is the wrong thread would somebody please move it to the correct one.

It is getting harder and harder to find Pokemon roms on the internet, so this guide should help anyone who has
the 2 in 1 rom.

How to extract Pokemon Red/Blue roms from Pokemon-Red-Blue-2-in-1 rom

0. Tools:

   Hex editor (I use HxD hex editor)
   Pokemon Red/Blue 2-in-1 rom (Google search)

1. Open the hex editor and click file new 2 times

2. Open the rom in the hex editor

3. In the hex editor search for offset 8000

3a. Or ctrl F and search for POKEMON BLUE

4. Copy everything from 8000 to 107FFF

5. Paste into one of the blank tabs and rename it to Pokemon and save it

6. Do the same steps to get pokemon red at offset 108000 to 1FFFFF

6a. Or use ctrl F for POKEMON RED

Note: Apparently Pokemon Red data ends at F7FF instead of FFFF like Blue,
but the game should still work properly.  Filling the end with 00s up to FFFF
will also work.

There are 2 versions of the Pokemon Red Blue 2 in 1

Pokemon Red-Blue 2-in-1 (Unl) [h1].gb and Pokemon Red-Blue 2-in-1 (Unl) [h1][a1].gb
this guide uses Red-Blue 2-in-1 (Unl) [h1][a1], but I have tested both of them for this guide.
