Warning: If you have already installed this patch and are reinstalling it for the new color correction, you gotta back up your save, or else you might lose all of your progress!
1) Dump your copy of either Pokemon Red, Blue, Yellow, or Green using Braindump. Once complete, eject the SD card, and find a file with a title ID and .cxi extension on the SD card. Copy this CXI somewhere safe, and write down the title ID.
2) Download CTRTool, and then place it into the folder with the .cxi file.
3) Open a command line prompt in the directory (you can do so by holding SHIFT and right-clicking with the mouse, then selecting the option).
4) Type the following commands:
ctrtool --exefs=exefs.bin --romfs=romfs.bin TITLEID.cxi
ctrtool --romfsdir=romfs romfs.bin
(Replace TITLEID with the title ID for your title)
5) Get yourself a ROM image of the game that you want to use the patch for, and then put it somewhere safe.
6) Locate the appropriate patch for your ROM, as well as for the language of your ROM. (For example, if you're using the German version of Crystal, you'd find 'germancrystal.bin.patch'.)
7) Extract the appropriate patch and keep it somewhere safe with the ROM.
8) Rename the ROM to match the patch NOT INCLUDING the .patch ending.
9) Open up the extracted RomFS of your copy of Pokemon Red/Blue/Yellow/Green.
10) Delete all of the files in the root of the RomFS with the extension of '.patch'. (This just saves space for the long run. You can skip this step if you want to.)
11) Place the new '.patch' file from somewhere safe into the root of the RomFS.
12) Go into the RomFS's 'rom' folder.
13) Delete whatever file is inside and replace it with the ROM you have from somewhere safe.
14) If you're going to be using Pokemon Gold and Silver, listen closely. Otherwise, skip ahead to Step 18.
15) Go back to the root of the RomFS and open up the patch file in a text editor.
16) Go to the very last patch at the bottom of the file.
17) Decide now whether you want to play the game in DMG (Original Gameboy) mode or GBC (Gameboy Color) mode. If you want to play DMG mode, leave the patch as is and exit. Otherwise, change the "Fixcode" to 0x80.
18) Exit out of the RomFS entirely and move into the ExeFS.
19) Find the 'code.bin' within the ExeFS.
