What Pokémon Peridot Version changes
How the game plays differently from Pokémon Crystal, then every stat, type and ability it alters next to what the official games do.
How the game plays
Pokémon Peridot Version is seatree's rebuild of Pokémon Crystal, written from the game's own disassembled code. The map is a region of its own — Elkhorn to Orchid, twelve towns, twenty-four routes and seven sea routes with nothing of Johto left in them — and the dex is stocked with designs from Gold and Silver's development that never shipped, drawn as the creator's own sprites and named by the creator. Three difficulties are picked before the first Pokémon is handed over. The region is only loosely ordered: the gyms sit on a route you can walk in more than one way, and four of the leaders answer that by bringing a bigger team once you have been further. Each gym is a gauntlet — its trainers first, the leader at the end. The Fairy type is here, and Ghost and Dark have swapped sides of the physical/special line, so Crunch is a physical move and Shadow Ball a special one. This guide is generated from the creator's own source tree at version 2.3.1.
Ghost and Dark have swapped sides
This game still decides a move's category from its type, the way Crystal does — but it moves two types across the line. Dark moves use Attack here and Ghost moves use Special Attack, the opposite of the official Game Boy games. Fairy is a special type. Every move page on this site shows the category this game gives it, and says so where it differs.
Your badges set the level your Pokémon will listen to
With no badges, anything above level 20 may refuse an order. The Fist or Wave Badge raises that to 30, the Mystic Badge to 40, the Root Badge to 50, the Glacier Badge to 60 and the Rising Badge to 70. Once you have entered the Hall of Fame everything obeys. On Relaxed the limit only applies to traded Pokémon; on Normal and Expert it applies to your own as well.
| Highest badge | Obeys up to |
|---|---|
| None | Lv 20 |
| Fist Badge or Wave Badge | Lv 30 |
| Mystic Badge | Lv 40 |
| Root Badge | Lv 50 |
| Glacier Badge | Lv 60 |
| Rising Badge | Lv 70 |
| Hall of Fame | Any level |
A leader's team depends on how far you have got
The region does not force one order on you, so four of the gym leaders check how much of it you have seen before they choose a team. What they look at is the towns you have reached — the places you can fly back to. Cecil has five teams, Duane three, and Murphy and Posey two apiece; the other four leaders have one. Every one of them is listed here with the condition that brings it out. After the Elite Four, all eight leaders take five rematch teams in turn, at levels 60, 70, 80, 90 and 100.
What Expert actually changes
Battles are set style, so you never get to switch when the other trainer sends something out. You cannot use an item in a trainer battle. You cannot change boxes unless you are outdoors. And a whiteout resets the game to the title screen instead of sending you to a Pokémon Center.
Two things roll their own level
A Pokémon you meet while surfing comes in at the table's level plus 0 to 4 more. A Pokémon under a smashed rock takes its level from your badge count — level 7 with none, up to 48 with all eight — plus up to four more on top. Every other table's level is exactly what the game stores.

How the Pokémon change
Measured from the guide's own data, so it can't drift from the pages it links to.
Compared against present-day official data. The Fairy type and hidden abilities arrived after Pokémon Crystal, so a difference here can belong to the series rather than to this hack.
