----SETUP INSTRUCTIONS START----
Scroll to the bottom of this page and download the IPS patch file for the version you want from the file list below. Use Lunar IPS 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----
Any v2.0 or higher save file should work in this new version - but I would recommend loading the save normally rather than loading a save state. You may experience strange behaviour if you load a save state during something that I have changed between v2.0 and the current version. If you are stuck in place on loading the save in the new version, use Fly, Teleport, or Pocket Abra to fix the issue. If you get a really bad bug on loading your save, try going to somewhere else on the old version (Viridian city pokemon center is a good choice), and saving there instead, then loading on the new version again.
v2.4.4 Patch Notes
Fixes for Bugs I caused:
- BUG: In Seafoam islands, for some reason you can exit surfing onto a rock ridge corner. FIXED - collision detection works properly for that tile now
- BUG: When your own pokemon faints, leech seed gets cleared on the opponent. FIXED - leech seed will not get cleared
Fixes for Bugs in the original game:
- BUG: When a glitch pokemon gets loaded, uncompressing its broken sprite data can corrupt hall of fame data. FIXED - cannot corrupt hall of fame data anymore
- BUG: After obtaining a fossil in mt moon B2F, the trainers on that level lose their sight range. FIXED - they keep their sight range now
