----SETUP INSTRUCTIONS START----

STEP 1: Scroll to the bottom of this page and download the .bps patch file for the version you want from the file list below.

STEP 2: Get the original unpatched game ROM as a file in .gbc or .gb format, international english, Red Version or Blue Version depending on the version you want to play. Search it up online or ask your friends how to get it. You can dump an official cart for example, but there are other ways as well! If you want to play PureGreen, get the original Blue Version ROM file.

STEP 3: Use an online patcher or the software Floating IPS to patch the original game. Basically, you are applying the .bps patch file to the original game's .gb or .gbc file.

STEP 4: Open the resultant .gbc or .gb file with software that can run .gbc or .gb files to play the game.

Always use these patch files on the original game's .gbc or .gb file. Don't try to use any on a game that's already been patched, or a previous version of PureRGB. It won't work.

2.7.5 Patch Notes

==QUALITY OF LIFE==

• Re-talking to the pokemon center nurse after healing your pokemon will not trigger her dialog again, instead she will just quickly bow to you. This resets after you move off of the coordinate that you talked to the pokemon center nurse. Avoids accidental re-triggering of nurse dialog.
• Added a "Currently selected pokemon" info box to the deposit/withdraw/release PC menus. This will show the pokemon's party icon, its species name (in case you nicknamed it) and its types. Just useful for people who sometimes forget which pokemon they gave which nickname.
• Created a new CopyVideoData function that can copy during HBlank as well as VBlank. It can copy >2x the tiles per frame than CopyVideoData can, so many graphics will load considerably faster than before. Improves the snappiness of menus, talking to NPCs, and most things in general in the game.
• Outside of battle, you can more quickly use items on your pokemon. The party menu will stay open if you have more of the item you're trying to use. The party menu will show how many you have left, and will automatically close when:

1. It cannot be used on any other pokemon after you used it (like Antidote with no poisoned pokemon in your party)
2. You used your last of the item

==MINOR TWEAKS==

• A lot of code was optimized, especially text data and text-related functions.
• Removed Route 18's trainer tips, moved it to route 13, and moved the one it replaced in route 13 to route 6 because it's a rather important tip that knowing earlier in the game is useful. Route 6's tip was about the PC's View Mode, which is kind of pointless now because of the new text prompts that indicate you can use it.

BUGFIXES

Fixes for Bugs in the original game:

• BUG: Using Mimic on a pokemon after the opponent switches will always copy the move to move slot 2 which can cause other issues. FIX: Back up the move slot data so it isn't overwritten by opponent switching
• BUG: Using Mimic on a pokemon after the opponent switches will cause incorrect tiles to be reloaded after displaying the player's mimic move selection menu. FIX: back up tiles in a better spot so they reflect the correct switched pokemon.
• BUG: After displaying the diploma for catching all the pokemon, there is a quick flash of previously-printed text before it disappears. FIX: Move the "Congratulations!" message to after the diploma is displayed to prevent this minor issue.
• BUG: In some cases, TownMapCoordsToOAMCoords function can try to write data to the game's ROM (which is not possible) FIX: stop that from being attempted
• BUG: Sort of a bug, sort of probably what they intended, when changing options from the "Continue, New Game, Options" main menu, option modifications are not actually propagated to the save data unless you "Continue" then save the game. FIX: If no save file has been created yet, when you exit the Options menu that was opened from the Main Menu it will just copy the options data into your SRAM so they persist as if you saved them. If you have a save file, it will save the game when you exit the options menu from the Main Menu. Basically, this is how people expect it to work.
• BUG: Garbage tiles can display for 1 frame at the end of the credits when rebooting the game. FIX: reboot in a slightly different way that doesn't do that.

Fixes for Bugs I caused:

• BUG: Uncapitalized "until i fix" in fossil guy's text. FIX: Capitalize it "until I fix"
• BUG: Using Mimic on a pokemon that has no moves other than MIMIC can get you stuck in a loop FIX: Make mimic fail in this specific scenario, and block Mimic'ing MIMIC in general. Randomized MIMIC (when opponent uses mimic or when it is used in a link battle) will never choose to mimic MIMIC.
• BUG: Accessing the player's PC directly (player's house PC) can incorrectly re-enable text delay while viewing the menu. FIX: Keep the correct text delays in this menu.
