Full Features / Bugfixes List

The only version differences between PureRed / PureBlue / PureGreen are visual. Play whatever color you like the most.

New Options in the Options Menu

Many options have been added to the game's options menu. To be clear, there are 4 pages of options now. Use the Next button on the options page to cycle through the pages when in-game.

The first page contains the original game's options. Text speed has an "Instant" option now, and the "Slow" option is now the original game's "Medium". The game defaults to "Fast" speed. Other than that, the way Battle Style and Battle Animations options work haven't changed.

The second page contains new big features related to general gameplay.

• The first option, COLORS will cycle between color palette options of the game. These only apply if you're playing on a system that supports color, like GBC, GBA, Super Gameboy, etc. Important to note: On Super Gameboy after changing this setting you will need to save and restart the game to apply the change. On GBC and GBA it's instant.

  • OG: Default color setting. The game will use whatever colors it originally would have had on the system you're playing on. In the case of GBC or GBA, this is a hardcoded limited dual-color palette. On SGB, this is the default SGB color palettes.

  

  • SGB1: Force SGB color palettes. This is no different than the "OG" setting if playing on SGB. On GBC or GBA, this changes the game to use the same color palettes as on SGB, and enables full color mode. Attack animations will have color in this mode when on GBC or GBA, along with some other color enhancements.

  

  

  • SGB2: Force alternate SGB color palettes. Access this option by pressing A on SGB1 in this options menu. This is the same as SGB1 with a couple minor differences in colors based on japanese pokemon green. A more greenish white color for all the palettes. Other minor color differences include: Pallet Town is purplish instead of light green. Pewter City, Lavender Town, Celadon City, Saffron City, and Indigo Plateau have slightly different main colors in comparison to SGB1. Other than these slight color differences it is the same as SGB1 in features.

  

  Pictured Below: Left = SGB1, Right = SGB2

  

  • GBC: Force GBC color palettes. On Super Gameboy, it'll now have Pokemon Yellow's GBC more intense color palettes. Same with GBC and GBA. On GBC and GBA, enables full color mode. Attack animations will have color in this mode when on GBC or GBA, along with some other color enhancements.

  

• The second option, ALT PKMN COLORS will enable or disable pokemon from being able to have special color palettes (Default: OFF). When turned on, features related to alternate color pokemon are enabled. In certain regions, you will find differently colored pokemon, like blue nidorinos and purple nidorinas. Think of them as regional color variants. This is just an amusing feature to allow for additional enjoyment in finding unique pokemon by exploring different places.

• The third option, MUSIC will enable or disable new music tracks in the game. (Default: OG) Set it to OG+ to play new music tracks when they are meant to be played. At the moment it controls only one or two minor tracks, such as Giovanni's Theme. (unused music from Pokemon Yellow's code) More music will likely be added in the future.
• The fourth option, AUDIO PAN will enable or disable stereo audio panning (Default: OFF). The game uses stereo audio by default, but every channel is played at equal volume throughout the right and left speaker, so it sounds like mono. With this turned on the game music sounds a bit more dynamic by panning certain channels to left or right. This was an option in Pokemon Yellow that was ported to this romhack.
• The fifth option, BIKE SONG will enable or disable the music that plays while on the bicycle (Default: ON). Since the bicycle music plays 100% of the time you are using the bicycle, it gets a bit old after a while. If turned off, the only time you'll hear the music is in Cycling Road. This way you can enjoy all the music in the game, not just the bicycle song.

The third page contains settings related to battles.

• The first four options, GHST→PSY, ICE→FIRE, BUG→PSN, PSN→BUG all control type matchups in the game. The option on the left for these is the original game's type matchup, and the right option is what it was changed to in Gen 2. These options allow you to fine-tune how you want type matchups to behave. The only non-original one is GHSTxPSY, which is set to make Ghost super effective against Psychic by default. In the original game Psychic was immune to Ghost, which the game even tells you isn't supposed to be the case in NPC dialogue.
• The fifth option, EXP BAR enables or disables an experience bar visual in battle. (Default: OFF) This feature allows easier tracking of experience while in battle.

• The sixth option, NPC EVs enables or disables giving opponent trainer pokemon Stat EXP based on their pokemon's level. (Default: OFF) In the original game, they receive 0 stat EXP regardless of the level of their pokemon. This means if the player has a lot of stat EXP, they will totally outclass similar-level trainer pokemon. Turning this feature on will give trainer pokemon stat EXP scaled with their level to a reasonable degree. This makes the game a bit harder but can be fun for more experienced players.

The fourth page contains Sprite-related options.

• The first option, BACK changes the back sprites in the game. (Default: OG) There are two possible settings:

  • OG: Use the original blocky back sprites.

  

  • SW97: Use the spaceworld 1997 back sprites. (some have been touched up a bit) These are higher resolution while still matching the original game's style. Very nice!

  

• The second option, ICONS changes the menu icons and overworld sprites in the game. (Default: OG) There are two possible settings:

  • OG: Use the original icons in the overworld and on the pokemon menu.
  • OG+: Use the original icons with some new ones. Some are based on beta sprites, some are completely newly designed sprites with the intention of being similar to the non-specific icon design of the original game, and ONE based on Gen 2's menu sprites (jellyfish sprite). This also will give unique sprites to Brock, Misty, Lt.Surge, Erika, Sabrina, and Blaine. They are all sprites that were designed from scratch to match the game's original trainer sprites, EXCEPT blaine's sprite, which is borrowed from Gen 2.

• If you press A on EDIT of the 3rd Option, it will open 4 new pages on another level. These 4 pages are for customizing the front sprites of the game.

You can customize the below sprites:

• The Name Rater will always be willing to rename pokemon, regardless of if you received them via trading. Is he going soft?
• When selecting where to Fly to on the map, there is no longer needless forced delay between each selection.
• The game now always reports the correct "Super Effective!" "Not Very Effective" etc. message when battling. No more tricks!
• HMs are deletable. Try not to delete them in a place where it will prevent you from leaving.
• When teaching a pokemon a move and selecting a move to forget, you must press START to select the move to forget instead of A. Now you won't accidentally select the wrong one disastrously!

New Gameplay Features

• Mew is under the truck!!! Use strength on it from the right side. If the SS Anne has left, it returns after obtaining the Soul Badge.
• Missingno and the item duplication glitch are still accessible. Missingno can be caught and won't corrupt your game data in any way. It's very powerful, so be careful when trying to catch it! Missingno also randomly displays different sprites like its original "glitchy" sprite, the Ghost sprite or Fossil Kabutops/Aerodactyl each time its sprite is loaded.

• And entirely new pokedex mode has been added. It's called the MOVEDEX. This tracks every move you have seen the animation of in battle, and will list all their information and data in detail for you to see. Try to complete your MOVEDEX! The movedex is unlocked in a new basement classroom of the schoolhouse in Viridian City.

• Ghost Marowak can be caught, and if you have Alt Pkmn Palettes turned on, it has a special ghostly coloration. It wants revenge on Team Rocket!

• The Safari Zone now has 3 different "Modes" of Safari Game. They are:

  • CLASSIC: the original game's "Safari Game". Use bait and rocks instead of your well-trained pokemon to try to catch wild pokemon with Safari Balls. The only change to this mode is that you have 700 steps instead of 500.
  • FREE ROAM: Bring your pokemon into the Safari Zone and catch and battle pokemon like you would normally. Also, no limit on steps! On top of that, now there are trainers ready to battle all over the Safari Zone? This is great! The trainers will reset when you re-enter, allowing you to repeatedly battle them.
  • RANGER HUNT: now we're talking. Find the 5 rangers and defeat them before you run out of steps! You get a special prize if you do! Bring in your pokemon just like FREE ROAM mode, but you only have 700 steps to find and beat all 5 rangers! All the trainers from Free Roam mode are present too. This is the ultimate Safari Zone challenge! The reward is a new type of Poke Ball, the HYPER BALL, which never fails to catch pokemon if they are <1/3 health. Even legendary pokemon! This challenge can be repeated.

  

• New Items:

  • POCKET ABRA: It's an Abra that fits in your bag. A pocket pokemon! Isn't that redundant?...It allows you to teleport whenever you want, even in buildings or caves, back to the last pokemon center. Keep it on hand at all times for maximum convenience. You can nickname it even!
  • BOOSTER CHIP: Replaces EXP.ALL - Oak's aide on Route 15 will give you this if you catch at least 80 pokemon. When you install it to your pokeball belt, all your pokemon will gain boosted EXP as if they were traded pokemon! Great for training up pokemon when you're trying to catch them all.
  • APEX CHIP: The Gym Guide's creation! It maximizes DVs (also known as IVs) when installed. The Gym Guide will give you 2 of them after you beat each gym leader. Inside a pokemon's pokeball, this chip will simulate their natural habitat, helping them be happy and achieve their maximum potential!
  • HYPER BALL: As discussed above, a new type of Poke Ball that never fails to catch pokemon if they're below 1/3 health. For many non-legendary pokemon, it will never fail even at full health! You might want to save these for legendaries because they're a bit hard to come by.

• The "TM Pirate" is a kid who appears in most PokeMarts who will sell you TMs! It's just a fun way of adding more purchasable TMs to the game.

• The urban legend - Bills Garden - was added into the game! It only is accessible once you become champ. You'll find some amusing stuff there. Visit it a couple of times! What you find might change! If you have alt palettes turned on in the options...is that a blue pikachu??

• The Mt Moon fossil Super Nerd will offer to take your fossil to Cinnabar Lab right away! You have to meet up with him at his house in SAFFRON CITY to get your fossil pokemon if you give it to him. Then you can give him OLD AMBER too. This allows you to receive fossil pokemon early.

• You can obtain the fossil that you didn't choose in Mt.Moon hidden inside Seafoam Islands.

• In Celadon City there is an NPC in the Hotel who will give you LAPRAS early after clearing Rocket Hideout. It's the same guy who gives you it in Silph Co on a business trip. He ends up stuck in Silph Co later on as expected! If you don't get LAPRAS early you can still get it the original way.

• In Fuchsia City there is an NPC who will permanently remove CUT trees for a fee. Remove all the trees in Fuchsia City, the one blocking Route 9, and more!

• If you have Alt Palette Pkmn option turned on, at the Cinnabar Lab there is an NPC who will allow you to swap the color palette of your pokemon for its alternate palette. You have a limited number of color change usages!

• A new area was added in the basement of the Viridian Schoolhouse. Acts as a sort of help area in the early game, with more info about basic stuff in the game like stats, type matchups, STAB, etc. It's also where you unlock the MOVEDEX feature.

• The FISHING GURU now lives in cerulean city and you can get the OLD ROD a bit earlier. Same with the GOOD ROD, which is now in the old FISHING GURU's house in vermilion city. As for the last two gurus on Route 12 and in Fuchsia city, whoever you meet first will give you a SUPER ROD. The other will be a bit distraught at the unexpected turn of events, and then give you a FISHING GUIDE. This unlocks the ability to see fishing locations for pokemon in the pokedex.

• You can phone home, professor oak, even your rival from the telephones in Celadon City's Department Store. You can choose how the conversations play out, and they even can have some subsequent small events based on what you choose when you go back to PALLET TOWN!

• After saving Mr.Fuji in the Pokemon Tower, you can get into the basement of the Tower. You'll find a Channeler clothed in black who just loves curses, hexes, and all that dark stuff. If you show them a GENGAR, they'll curse it to look like a HAUNTER again. Its stats won't be affected though. It'll still have GENGAR's stats. Such a powerful curse!

• A secret stairway opens up in a building somewhere after you become champ. The last in-game trade and some interesting stuff to see is in there.

• The above secret area will help you access an even more top secret area. This area involves MEWTWO. You may want to bring MEWTWO with you. Maybe even MEW too! What you may find will be interesting.

• A couple of items or TRAINER TIPS signs have been added to otherwise empty places in the overworld.

• A couple of new hidden items were added to various areas in the game.

• Multiple items can be picked up at once (example: you found 5 potions)

• Donate some money to the rock tunnel pokemon center to hear the secret of the pokemon centers: holding B before talking to the nurse will give you very express service!

• Someone will sell every single TM after becoming champ.

• Rare candies can be purchased after becoming champ, but you must do a bit of sleuthing to find out how.

• The two extra viridian forest trainers from Yellow were added in to make it a bit less empty

Restored Cut Content

• If you turn on OG+ Music mode, the cut content Giovanni theme will play when you encounter Giovanni
• There is unused text in the game for when you lose to your rival - these were re-implemented and now work as expected!
• There was an unused trainer class for Prof Oak. It's been added back into the game. Find him in Cerulean Cave after beating the Elite Four. He can be battled repeatedly. Just leave the area and come back.
• Some trainer classes based on Beta or unused sprites were reintroduced to the game: ROOKIE, RANGER, FIREFIGHTER, COOL KID, SOLDIER, CHIEF. You'll find them in previously empty places or routes!

• There were unused icy-looking tiles in the Cave tileset that were meant to be used in seafoam island. Now they are used there!
• Some unused trainers from existing classes were added into the game in various originally empty places

• Pokeballs have varying animations slightly based on the type you use. Master Ball is especially cool!

• Using SGB1 or SGB2 colors, lorelei's room is a similar color to seafoam islands (it was the same color as Pallet Town previously).
• Using GBC color mode, the "Grey pokemon" palette was made less brown.
• Spaceworld backsprites were tweaked to improve them a bit
• A couple of front sprites were tweaked very slightly to improve their appearance
• Some pokemon had their default color palette adjusted (example: Voltorb and Electrode are red instead of the original yellow. Don't ask me why they were yellow in the first place)
• You can see "the side of the building" visually from Celadon Department Store roof and Celadon Mansion roof.

Bugfixes

• High Jump Kick / Jump Kick crash damage on missing does more damage instead of 1 damage always now. (1/4 the damage of what it would have done to the opponent)

• Koga says the Soulbadge boosts defense, but in the code it actually boosted speed. Now it boosts defense as the text indicated.
• When learning a new move in battle, the "Poof!" sound effect didn't work correctly and would play a random sound instead. Now it works.

  • BONEMERANG - 55 base power, hits twice, 90 accuracy, 30% chance of lowering opponent's speed.
  • SUPER FANG - now deals a set 2/3 the opponent's HP instead of 1/2. Useful for catching rare pokemon!
  • TELEPORT - actually does something in trainer battles now! The user will switch out, and heal 25% health by doing so. Still works the same as it used to when wild pokemon use it.
• There are many more tweaks to moves. Check your MOVEDEX in game to see what a move you just saw's effects were, or see the wiki for a link to the complete move list. Be sure to try almost every move and don't write them off. Except for splash. It still does nothing as usual.

Trainer AI changes

• AI won't spam agility or amnesia repeatedly just because your pokemon is weak to psychic moves. The subroutine for selecting super effective moves ignores moves that do no damage now.

Things that Will Remain Unchanged

• I will not make the game use Gen 2 colors/tilesets/music/sprites/etc.
• I will not implement the physical/special split. I balanced the game around there not being one.
• I will not split the SPECIAL stat into SPECIAL DEFENSE and SPECIAL ATTACK. I balanced the game around the combined special stat.
• I will not add dark, steel, or fairy type.
• I will not mess with the type matchup chart outside of the tweakable options already provided.
• I will not make a version without the base stat changes
• I will not make a version without the move changes
• I will not make a version without learnset / TM / trainer party changes
• I will not add beta pokemon to the game (just about all of the decent beta mons for gen 1 were already repurposed as official pokemon in later games)
• If you want less changes but still the quality of life / bugfix stuff, I'd recommend taking a look at the romhack called shinpokered.
