FRLG EV Trainer

[theastrogoth]

This adds a basic EV Trainer for FLRG. The user can input a number of EVs to be earned for each stat, and the program will navigate to appropriate areas and grind wild encounters.

Some tools that were added to enable this:

• BattlePokemonDetector for determining if a Pokemon is on the field (or has fainted)
• MapDetector for opening the Fly map, along with a function for navigating to all Kanto fly spots
• WildEncounterReader for determining the species of a wild encounter. This could be extended to also detect level and gender, but it isn't necessary for EV training.

In-game setup:

• Put the Pokemon you'd like to EV train in the lead. Make sure its first move is a damaging one
  • if doing Speed training, it should have a non-ground and non-ghost move.
  • if doing Sp. Attack training, it should have a non-normal, non-fighting, and non-ground move
  • ideally, the move does not have a low maximum PP
  • it should be a high enough level to defeat relevant wild encounters:
    • HP: Caterpie in Viridian Forest (Lv 5)
    • Atk: Mankey on Route 22 (Lv 5)
    • Def: Geodude and Onix in Rock Tunnel (Lv 17)
    • SpA: Gastly and Haunter in Pokemon Tower (Lv 20)
    • SpD: Tentacool while Surfing (up to Lv 40)
    • Spe: Pidgey and Rattata on Route 1 (Lv 4)
• Put a Pokemon that knows Fly in the last spot of your party (which doesn't need to be full).
  • The Thunder Badge needs to have been obtained.
  • Visit PokeCenters in Viridian City, Pewter City, Route 10, Vermilion City, and Lavender Town to unlock them as Fly spots
• If training any Defense or Sp. Attack EVs, put a Pokemon that knows Dig in the second-to-last spot of your party
• If training any Sp. Defense EVs, one Pokemon in your party needs to know Surf
  • The Soul Badge needs to have been obtained.
• Start the program from anywhere in the Kanto overworld

I don't have Surf unlocked in my current playthrough, but I will implement and test the Sp. Defense EV training once I get there.

Since some common navigation functions were modified, Pickup Farmer has been changed slightly here as well. It should now be better able to handle evolutions and can make use of Fly as well as Teleport.

The user setup for this might be a bit of a doozy. The biggest headaches come from needing a Dig user for exiting Rock Tunnel and Pokemon Tower and a Surf user for farming SpDef EVs from Tentacool, as well as from type immunities that some encounters have.

There aren't many wild encounters with SpAtk EVs, unfortunately, especially in Leaf Green, so we're kind of stuck with Pokemon Tower for those. SpDef can be farmed from Drowzee on Route 11, which would avoid the need for Surf but would be noticeably slower.
