----SETUP INSTRUCTIONS START----
Scroll to the bottom of this page and download the BPS patch file for the version you want from the file list below. Use Floating IPS or an online patcher to patch pokemon blue for PureBlue or PureGreen. Patch pokemon red for PureRed.
Always use these patch files on the original english game. Don't try to use any on a game that's already been patched.
----SETUP INSTRUCTIONS END----
The game now has a save file updater. If you use a save file from a previous version or even the original game, the game will update the save and everything should work fine. Please indicate whether you came from an earlier version or the original game if the game asks. It will also ask you whether to warp to PALLET TOWN. It is recommended to warp to PALLET town when you update your save. Otherwise you might end up in a glitched position.
