• The “Hot House” (beach house on Route 109, formerly 3 mini bosses to earn a Charcadet) has been reworked to be an Elite 4-style gauntlet with varying rewards that the player can choose from:
  • Has 6 levels of rewards that the player can choose from, reward levels are unlocked based on number of badges player has
  • 2 badges: player can choose between Tyrogue, Pansage, Pansear, Panpour
  • 3 badges: player can choose between Misdreavus, Heracross, Pinsir, Scyther
  • 4 badges: player can choose between Eevee, Magby, Elekid, Smoochum
  • 5 badges: player can choose between Togepi and Riolu
  • 6 badges: Type: Null
  • 7 badges: player can choose between Charcadet and Aerodactyl
• How the Hot House gauntlet works: to access the Hot House, talk to the little girl out front. After choosing the reward you want to compete for, you will be sent into the Hot House, where you cannot leave or access your PC until you defeat the 3 trainers inside or white out (again, think mini E4-style gauntlet, you can heal and change items/moves/abilities while inside). The 3 trainer teams will change based on which reward level you are competing for, but will not change within a reward level. For example, if you choose to compete for Pansage in one attempt and then Pansear in another, you will face the same teams since they are both 2-Badge level rewards. However, if you later decide to compete for Heracross, you will face stronger teams since Heracross is a 3-Badge level reward. You can challenge the Hot House as many times as you want and even get the same reward over and over again if you so choose
  • The Hot House is now also its own encounter location separate from Route 109
• As a result of the Hot House rework, the gift Eggs for Togepi, Riolu, Eevee, and Type: Null have been removed or replaced with Eggs that pick from a pool of random Pokemon (more on that below), and the gift Tyrogue has been removed from Daisuke.
  • Togepi Egg in Rustboro City was replaced with an Egg in Oldale Town that contains a Pokemon from a pool of early game Pokemon including: Sentret, Jigglypuff, Kricketot, Cubone, Pancham, Yamper, Rockruff, Snorunt, Spoink, and Varoom
  • Riolu Egg has been removed entirely
  • Eevee Egg in Lavaridge Town was replaced with an Egg in Lavaridge Town that contains a Pokemon from a pool of mid game Pokemon including: Tauros (Kanto), Delibird, Tropius, Spiritomb, Heatmor, Dedenne, Bruxish, Falinks, and Klawf. The player can obtain multiple of these Eggs in exchange for Yellow Shards
  • Type: Null Egg in Lilycove City was removed and replaced with an Egg in Pacifidlog Town that contains a pool of Pseudo-legendary Pokemon including: Dratini, Larvitar, Bagon, Beldum, Gible, Deino, Goomy, Jangmo-o, Dreepy, and Frigibax. The player can obtain multiple of these Eggs in exchange for Yellow Shards

  • Option to increase overall battle speed (credits to Phantonomy)
  • Option to increase health-bar drain speed

  • Note about these, if you set them before starting a new game, they will reset after the game has started. This is a known bug that for technical reasons cannot be fixed until later (source: trust me bro)
• Added a new option the the L Menu called the “NuzVial”
  • The NuzVial is only available in gauntlets that the player cannot leave (Hot House, Elite 4)
  • It is functionally the PokeVial, but it does not apply to fainted Pokemon

• Players now have the ability to Fly using the Pokenav after defeating the Rival in Rustboro instead of from the Rival on 110
  • This is a workaround to the Briney softlock
  • If you update your game after the Rustboro Rival but before the 110 Rival, you may manage to avoid receiving this feature, so be careful

NOTE: The numbers in parentheses next to some of these changes represents a pull request number into emerald-expansion (the base for this hack). It is mostly there for my own internal tracking purposes and you don’t have to worry about it!

• AI’s Pokemon can now be pre-statused! This will be indicated in the Boss Battles Doc, see Juan’s Ursaluna for example
• AI will no longer attempt to status you if you have abilities that benefit from it; Guts, for example (6550)
• AI will no longer use Scald or other fire moves on Frostbitten Pokemon unless it is extremely beneficial to do so (can KO for example) (6442)
• AI will no longer go for set up moves when facing a Pokemon with the Unaware ability (6524)
• In situations where the AI has a slow KO and a last-chance priority move (meaning it has a priority move, but is also is getting fainted by the player), the AI now has an 80% for the last-chance priority move to be scored higher than the slow KO move
• AI can now see it has a Focus Sash when considering switch-ins and determining number of hits to be KOed, applies to both mid-turn switches and post-KO switches (6436)
  • AI should now see its own and the player’s Focus Sash / Sturdy in all its calculations
• AI can now see that Magic Guard affects Mind Blown and Steel Beam
• AI can now factor in its own weather-setting abilities when determining switch-ins (7373)
• AI should now correctly see all scenarios where either itself or the player are Choice locked
  • Will now switch if it is Choice locked into a move that cannot hit the player’s Pokemon (6464)
  • Will now factor in the player’s move they are Choice locked into when determining hits to KO (6343)
  • Will no longer consider other moves when searching for its own supereffective moves while Choice locked (6892)
• AI will now be encouraged to use a pivot move if they have Palafinn on the field to activate Zero to Hero (6791)
• Absorb AI Switching (the following are checked in order in code)
  • AI will now see Mold Breaker when factoring in switches for Absorb Abilities (6864):
  • In situations where Absorb Switch AI is being considered, if the AI’s mon on the field has a super effective move, it will now switch 40% of the time instead of 33% previously
  • AI will now switch into a mon with an Absorbing Ability 100% of the time if the player is Choice locked into a move it can absorb
  • AI will now switch into a mon with an Absorbing Ability 80% of the time as the default case instead of 100% previously
• AI will now recognize when the player has Absorb Abilities when determining if its moves are effective (7309)
• AI will now score Magnitude and Present as their average damage amounts instead of 0 (7334)
• AI will no longer get a flat decrease to Explosion moves, and had some custom handling added to determine when it should consider using Explosion moves to pick up KOs (see section at bottom)
• AI will no longer be encouraged to go for setup moves when the player is at full health and has Sturdy, is holding a Focus Sash, or is Mimikyu-Disguised (7345)
  • Fixes AI spamming setup moves into these mons because they never see OHKO
• AI will no longer be encouraged to go for stat dropping moves when the player is at -4 or lower for the given stat category
• AI will no longer be discouraged from going for Shell Smash if they are not a mixed attacker
• AI will now prefer to go for an extremely low damaging move over a move that has no effect at all in certain very unfavorable situations (7350)
• Added rudimentary 1v1 calculation to Bad Odds switching so Pokemon that win a 1v1 won’t switch even if they have no effective move and / or a bad type matchup (6927)
• “Defensive switchin candidate” changed to require winning the projected 1v1 in addition to just taking more than 3 hits to KO (6927)
• Improved Substitute/ Shed Tail switch AI (6334)
• Improved AI’s defense against Focus Punch (6713)
• Improved AI’s setup scoring vs Haze (and other Haze-like effects) (6894, 6966)
• Improved AI’s move scoring when considering using Hazard moves when the player has moves that can clear them (6311)
• Improved AI’s ability to determine when it should go for a recovery move, including Strength Sap (7342)
• Improved AI’s ability to see priority moves. The AI should now be consistently factoring in both its own and the player’s priority moves for all scenarios (switch-in 1v1s, setup move scoring, normal move scoring, etc) (7337)
• Improved AI’s ability to choose moves when facing a Pokemon holding a supereffective move reducing berry:
  • Before: If AI sees it can 2HKO the player through a resist berry, it will pretend the berry is not there when doing its damage calc. This led to situations where the AI thought it could OHKO the player, and the AI could choose to go for a 2HKO through a resist berry instead of an OHKO with another move.
  • Now: If AI sees it can 2HKO the player through a resist berry, it will pretend the berry is not there when doing its damage calc. However, now if the AI has to choose between a move that is not affected by a resist berry and a move it “thinks” can OHKO because it is ignoring the resist berry, it will choose the move that is unaffected by the resist berry and can actually OHKO the player. This means the AI will no longer choose a move that can 2HKO through a resist berry over a move that can OHKO.
• This is factored into the “compare damaging moves” functionality described at the bottom
• Fixed various things in the AI’s damage calc formula (6396, 6397, 6733, 7130)
• Fixed potential double switching caused by Wonder Guard (6737)
• Fixed cases where AI could see Zero-Hit-KOs for switch-ins, which caused many strange switches (7131)
• Fixed cases where AI could incorrectly see it has a free switch after the player uses a pivot move, causing it to make some bad switch-in decisions (6498)
• Fixed a bug where AI could potentially not see what stat it was boosting correctly for setup moves (7346)
• Adjustments for move comparison scoring (7301 + what iriv changed)
• AI can now adjust its switch scoring based on its move scoring (6615)
  • If all the AI’s moves score beneath 90, the Pokemon will switch out
  • If the AI has a switch out effect move (U-Turn, Chilly Reception, etc.) that scores above 100, the AI will cancel any switch it is considering and stay in (probably to use that move, but not necessarily)
• Reworked the “type matchup” formula that is used to determine if an AI Pokemon has a “good defensive matchup” (7364)
  • In the following description, Atk1 represents the “primary type of the attacking Pokemon”, Atk2 represents the “secondary type of the attacking Pokemon”, and same for Def1 and Def2
  • Previously, the formula was:
    If the result of this equation was less than 1, then it’s a “good type matchup”:
    (Atk1 -> Def1) x (Atk2 -> Def1) x (Atk1 -> Def2) x (Atk2 -> Def2)
  • Example of the old formula that would result in a poor decision from the AI: the player has a Poliwrath, and the AI has a Ceruledge in its party and is trying to determine a good switch into the Poliwrath.
    Going through the old formula, we would see:
    (Water->Fire=2) x (Fight->Fire=1) x (Water->Ghost=1) x (Fight->Ghost=0) = Total: 0
    This meant that even though Ceruledge is probably a bad matchup into Poliwrath because Water is supereffective on Fire, the AI would see it as a good matchup because Ghost is immune to fighting. Type immunities like this are the most obvious example of where the old formula led to poor decisions, but there were others as well.
  • The new formula is:
    If the result of this equation is less than 2, then it’s a good type matchup:
    ((Atk1 -> Def1) x (Atk2 -> Def1)) + ((Atk1 -> Def2) x (Atk2 -> Def2))
    Notably, immunities are treated as 0.1 instead of 0 here!
  • Let’s use the same example with the new formula:
    
    ((Water->Fire=2) x (Fight->Fire=1)) = 2 +
    ((Water->Ghost=1) x (Fight->Ghost=0)) = 0.1
    2 + 0.1  = Total: 2.1
    And since 2.1 is greater than 2, this is considered a bad type matchup!
  • Some other examples of cases where the new behaviour makes improvements:
  • Player’s Camerupt -> AI’s Bellossom used to see Bellossom as Neutral, now sees Bad
  • Player’s Toxicroak -> AI’s Aggron used to see Aggron as Good, now sees Bad
  • The immunity value is specifically less than 0.125 because that threshold ties quad resistances; with 0.125, Aegislash sees the same matchup into a mono Fighting mon as it does into a mono Bug mon, where it is obviously better into Fighting. Having that multiplier at 0.1 instead keeps this behaviour.
• Added custom handling for the AI considering Explosion moves that makes its likelihood to consider Exploding scale with the amount of HP it is missing:
  • If the AI has >= 90% HP, it has a 0% chance to consider Exploding
  • If the AI has <= 10% HP, it has a 90% chance to consider Exploding
  • All chances to consider Exploding for HPs between 10% and 90% are calculated with the following formula:
  • RandomNumber(0-255) < X where:
  • X = ((90 – %HP) * 229) / 80
  • So at 50% HP, the AI has a roughly 45% chance to consider Exploding
  • This formula is run at the beginning of when the AI is choosing its moves to determine if it should consider moves with the Explosion effect
  • If this check fails, Explosion moves will get a flat -10
  • Explosion will also get a flat -10 if the target is immune to it (Ghost type into normal-type Explosion for example)
  • Explosion will also get a flat -10 if the ability Damp is on the field
  • Explosion effects will also be seen as negative effects when comparing between 2 damaging moves
• Fix AI not calcing Explosion damage with halved defensive stats for the target
• Reworked some of how AI compares its damaging moves (AI_CompareDamagingMoves for those that look at the code) (7337 + some other custom work)
  • The following is the new order of importance when comparing 2 damaging moves:
    1) Fewest number of hits to KO
    Then the following are checked for moves that have the same number of hits to KO
    2) If number of hits to KO is 1, then give preference to priority moves if the AI is outsped otherwise
    3) Give preference to moves that are not 2-turn attacks (Solarbeam, Phantom Force, etc)
    4) If number of hits to KO is 1, then give preference to moves that are not affected by a resist berry that the player is holding
    5) If number of hits to KO is 1, then check min rolls and give preference to moves that are guaranteed OHKOs, if any
    6) Give preference to moves that do significantly more damage than other moves. “Significantly” here is defined by seeing if one move’s lowest roll does more than another move’s highest roll. This check is not run if there are 2 moves that are guaranteed OHKOs.
    7) Give preference to moves with higher accuracy
    8) Give preference to moves with better secondary effects
  • The overall goal of these changes was to try and keep a smart and unique move selection criteria that is not just “always pick highest damage move”, while also giving some incentive for higher damage moves in situations where it is very obvious that a move does a lot more than another
• Slight rework to how AI decides to use Fast Pivot Moves (U-Turn, Volt Switch, Parting Shot, etc when the AI is faster)
  • Pivot moves are no longer seen as a positive effect when comparing 2 moves of equal scoring
  • The criteria for the AI to get an explicit score increase for a fast pivot are now:
    • AI is faster
    • AI can not KO the player
    • AI has a mon that can reasonably switch in (determined from previous switch checks)
    • The AI mon on the field has >= 33% HP, or 25% HP and regenerator
    • AND One of the following is true:
      • The player can KO the AI Pokemon
      • The AI does not have any stat boosts, has a good switch in candidate, and can break the player’s Sturdy/Focus Sash/ Shadow Shield/ Multiscale
      • The AI does not have any stat boosts and generally has a good switch in candidate
