Features

Graphics

• Gen 2 style HP bar, EXP bar in battle and on the status screen
• Caught (Poke Ball) icon on wild Pokémon you already own
• Every Pokémon has its own party icon, in its battle colors (party menu, nickname screen, PC)

Shiny and gender preview

• Sparkle next to any Pokémon that will be shiny in Gen 2
• Male/female symbol showing the gender Gen 2 will assign
• Shown in battle, on the status screen and in the PC

• INSTANT TEXT option
• Instant battle start: no transition, no slide-in, no opening messages

Convenience

• Bill’s PC shows how many Pokémon are in the current box
• A message says how many box slots are left when a caught Pokémon goes to the box

Bill’s PC: MOVE PKMN (Gen 3 style box screen)

• The box as a 5×4 grid of icons with the party beside it
• Pick up a Pokémon and put it down anywhere: reorder, deposit, withdraw, or swap with another
• Switch boxes with left/right on the box title, or from the box list
• Carry a Pokémon from one box to another
• Quick mode (START): A picks up and puts down without the menu
• SORT the box by Pokedex number, level or name
• Shiny mark on icons
• Box list shows the count of every box (e.g. BOX 3 12/20)
• STATS and RELEASE from the grid
• The old WITHDRAW / DEPOSIT / RELEASE lists are still there

Compatibility

• Pokémon data is identical to the cartridges: trades and battles with clean Red, Blue and Yellow, and Time Capsule trades with Gold, Silver and Crystal
• Save files work both ways with the original cartridges

Generation 1 Pokémon have no shiny flag and no gender. Gold, Silver and Crystal work both out from a Pokémon’s DVs, the hidden values every Red/Blue Pokémon already has. This game reads those same DVs and shows you the answer early: a sparkle if the Pokémon will be shiny in Gen 2, and the gender Gen 2 will give it. The rule is Gen 2’s own, so what you see here is what you will see after a Time Capsule trade.

The indicators are display only. Nothing is written to the Pokémon, and no shiny or gender data is added, because none exists in Gen 1. Every Pokémon is stored exactly as a regular cartridge stores it: same format, same values. Trades with unmodified Red, Blue and Yellow and Time Capsule trades with Gold, Silver and Crystal were tested, and species, DVs, stat experience, moves, PP, level, OT, ID and nickname all arrive unchanged. Save files move freely between this game and the original games.

One thing to know: the game uses the shiny patch’s random number generator, so wild Pokémon can roll shiny DVs at the standard 1 in 8192. That changes the dice, not the data. The DVs it rolls are ordinary values that any cartridge Pokémon can hold.
