Remake From: Pokemon Crystal
Remake by: Rangi
Description:
Polished Crystal is, as the title says, Crystal version but improved. The storyline is the same—you start in New Bark Town, beat the Johto gyms and the Elite Four, then move on to Kanto and fight Red.
Features
This isn't a complete list, just a summary of the notable ones.
Pokémon:
The entire Pokédex of 253 Pokémon can be caught in one game. Some Pokémon, like Houndour, Murkrow, and Misdreavus, are available at sensible locations in Johto without having to wait for Kanto.
Added: Leafeon, Glaceon, Sylveon, Togekiss, Weavile, Honchkrow, Mismagius, Electivire, Magmortar, Magnezone, Tangrowth, Rhyperior, Porygon-Z, Yanmega, Gliscor, Mamoswine, and Munchlax.
Removed: Spearow, Fearow, Lickitung, Goldeen, Seaking, Hoppip, Skiploom, Jumpluff, Shuckle, Aipom, Stantler, Cleffa, Igglybuff, Smoochum, and Delibird. (I miss them too. )
New evolution methods work, like Eevee evolving into Glaceon near Ice Rock, or Yanma evolving into Yanmega when knowing AncientPower.
Item trade evolutions (like Seadra holding a Dragon Scale) now evolve by leveling up while holding the item.
Machoke, Graveler, Haunter, and Kadabra evolve by having sufficient stat exp in Attack, Defense, Speed, and Special respectively (five Protein, Iron, Carbos, or Calcium is enough).
Magneton evolves into Magnezone near the Lodestone in Rock Tunnel.

Removed: Acid Armor, Amnesia, Barrage, Beat Up, Bide, Bind, Bone Club, Bone Rush, Bubble, Clamp, Comet Punch, Constrict, Conversion2, Cotton Spore, Detect, Fissure, Frustration, Guillotine, Horn Drill, Jump Kick, Kinesis, Lovely Kiss, Meditate, Mega Kick, Mega Punch, Mimic, Mind Reader, Mirror Move, Poison Gas, Powder Snow, Present, Psych Up, Psywave, Razor Wind, Rolling Kick, Sharpen, Skull Bash, Smog, Snore, Spider Web, Spite, Sweet Scent, Synthesis, Tail Whip, Vice Grip, and Withdraw.
Learnsets have been updated close to Gen VI, with missing moves replaced by similar, egg, TM, or event-exclusive moves.
Battle mechanics:
The Fairy type, with the Pink Bow as its type-enhancing item.
Type chart, base stats, and move attributes all updated to Gen VI.
Physical/Special/Status split.
Natures (determined from DVs since personality values don't exist in Gen II) thanks to FredrIQ.
Gain experience from catching Pokémon.
Play low-pitched cries when a player or foe Pokémon faints.
Money loss formula from Gen V.
Shiny Pokémon now have an odd Attack DV, 2, 3, 7, or 11 Defense, 5 or 13 Speed, and a perfect 15 Special; so 1 in 1,024 Pokémon is shiny.
Type-enhancing items raise by 20%, not 10%.
Many battle mechanics have been updated to Gen VI, but not all. (For example, Waterfall has a 20% flinch chance, but sound-based moves don't bypass Substitute. Yet.)
Wild Pokémon have more common held items (50% chance for a common one and 5% for a rare one). Giving an Amulet Coin to your lead Pokémon increases this to 60% and 10%.
Overworld mechanics:
Hold B to use Running Shoes, or turn on the Option to always use them.
Unlimited-use TMs.
Continuous Repel system.
Cure poison when it reaches 1 HP outside a battle.
Eggs hatch at level 1.
Trees randomly give 1, 2, or 3 Berries.
Surf at Bicycle/Running Shoes speed.
Maximum $9,999,999 money and 50,000 coins.
Maximum 30 items and 16 Balls in your bag pocket.
Bill calls to switch boxes when one is full.
Nuzlocke mode:
Available in the Option menu at any time.
A fainted Pokémon can't be revived, by items, Pokémon Centers, or events. The only exception is your first rival battle, when you just have your starter.
You can only catch the first Pokémon you encounter in a new location. "Location" is defined with the Town Map mechanics, so Sprout Tower is separate from Violet City, but multiple floors of Union Cave or multiple sections of the Safari Zone count as one location. And nothing is counted until you receive your first five Poké Balls.
Every Pokémon gets a nickname, no asking whether you want to or not. Of course, you can cancel out to give the default name.
The dupes clause is in effect. If you've caught a Pidgey and encounter one on a new route, it won't count unless you catch it.
The shiny clause is also in effect. Shinies can always be caught.
Gift Pokémon do not count as encounters. Static encounters like Sudowoodo, Snorlax, and Suicune do.
Maps:
Restored locations from R/B/Y and HG/SS: Viridian Forest, Pewter Museum, Celadon Hotel, Silph Co., Pokémon Mansion, Seafoam Islands, Cerulean Cave, Goldenrod PokéCom Center, and Bellchime Trail.

Eusine shows you the legendary beasts in Celadon City in case you haven't found them roaming.
Respawn any fainted legendaries (except for Celebi) after beating the Elite Four. (Suicune roams instead of appearing in Bell Tower.) (Also respawns Sudowoodo.)

Moon Ball catches Moon Stone evolvers.

No badge boosts to stats or types.

Changes and buffs:
Many base stat changes, mostly based on Drayano's Sacred Gold/Storm Silver.
Cut is Steel-type, and has 60 power and 100% accuracy.
Hidden Power is ???-type and has 70 power.
Metronome is ???-type.
Sing has 75% accuracy (matching Lovely Kiss).
Supersonic has 65% accuracy.

Pain Split is Ghost-type.
Some Pokémon have new types (for example, Ledian is Bug/Fighting, Persian is Normal/Dark, and Dunsparce is Normal/Ground).
I know that not everyone likes this kind of change, so I've provided two ROM patches. The "faithful" patch keeps the canon Pokémon stats and move attributes.
Graphics and music:
Restored original Japanese sprites for Beauty, Fisher, Medium, Sage, and Swimmer♀.
Replaced Twins sprite with a devamped one from B/W.
New music ported from RBY and devamped from future generations.

Unown isn't the only Pokémon with variant forms…
