Shin Pokémon Red and Blue: Lite Patch

Version 1.23

Future bugfixes here will be eventually migrated to the Shin Pokemon Red/Blue master branch

#Patch Info

BPS patches are provided for entry into your preferred emulator, patching tool, or other accessory that supports the BPS format.
Download and enter a patch which corresponds to the ROM of which you own a lawful copy.

• Red patches (shin pokemon red, red_origback, and red-jp) are intended for USA Red.
  • MD5 Hash: 3d45c1ee9abd5738df46d2bdda8b57dc
• All other patches (Blues and Greens) are intended for USA Blue.
  • MD5 Hash: 50927e843568814f7ed45ec4f944bd8b
• The "_origback" patches are alternatives that keep the original back sprites.

Includes Pokemon Green and Japanese Red!

• The compiler primarily builds the graphics and cerulean cave layout back to the original japanese release.
• Pokedex entries adapt the original Green version text that was translated in Fire Red.
• Pokedex uses metric units.

Now Includes Japanese Blue!

• Primarily builds the lists for encounters, trades, and prizes that were in the never-localized japanese release.
• Pokedex uses metric units.
• Other minor graphical adjustments.

Updating Your Save File Deactivate all special options and NPC toggles in the old save if it's from an earlier patch.
When loading an old save file with the latest patch, the player is automatically warped to Pallet Town.
Normally this will be enough to update the save file without doing anything else.
It's possible you may still have issues upon loading a save from a previous patch or an unpatched game.
To prevent this from happening, save in the outdoor Pallet Town map on the old save.
You might be blocked by invisible walls upon loading the game.
To fix this, you must use the Softlock Warp detailed below to teleport back to Pallet Town.

#Compatibility Notes

• Certain emulators are known to cause bugs due to inaccuracies in replicating the original hardware
  • An accurate emulator, preferably a GBC-dedicated emulator, is required in order to avoid unexpected bugs
  • Goomba and Pizza Boy in particular are known to be problematic
  • BGB is the supported standard due to its accuracy and debugging tools
• Compatible with original Gameboy hardware (DMG, Super, Pocket, Color, Advance, SP)
• Potentially compatible with Pokemon Stadium 1 & 2 (using original Nintendo hardware)
• Might be possible to use a save from vanilla USA red/blue with this rom hack
  • Save outside in Pallet Town before transferring over
  • Use the Softlock Warp to clear any invisible walls
• New builds are tested and debugged with the BGB 1.5.8 emulator and verified using original hardware
• Link trading with an original retail cartridge appears to work properly on real hardware
• Link trading between the lite and master branches appears to work properly on real hardware
• Link battles are still largely untested, and they are unsupported in the following ways:
  • Link battling between a master branch build and any other non-master branch build
  • Link battling between a lite branch build and any other non-lite branch build
  • Link battling between builds of dissimilar revisions
• A revision control function has been added that will cancel unsupported cable links

  • Burn & Paralyze stat penalties are now properly applied after Speed & Attack stats get updated/recalculated
  • Badge stat-ups don't get stacked anymore

  • The BIRD type has been reinstated and renamed to TYPELESS. It acts as a universally neutral type (particularly for Struggle)
  • AI trainers have priority on switching or using an item

    • Damage factor is now 2*(2level)/5 + 4 instead of 2(2*level)/5 + 2 to simplify some algebra
    • If non-crit damage would be >= crit damage, the regular modified stat values are applied instead

• Move fixes

  • Transform-related fixes:
    • Move slots cannot be rearranged when transformed (prevents acquiring glitch moves).
    • Transform will no longer copy the opponent's Transform move. It's swapped-out for Struggle
    • Enemy DVs can no longer be manipulated by having it use transform multiple times

  • healing moves work with restoring exactly 255 or 511 hp
  • light screen and reflect now have a cap of 999
  • Haze removing sleep/freeze will not prevent a multi-turn move from getting stuck (also fixes the sleep-trap glitch)

  • fixed-damage moves (seismic toss, dragon rage, etc) can no longer critically hit
  • fixed-damage moves now obey type immunities
  • fixed-damage moves now ignore effectiveness text & sfx
  • Struggle is now TYPELESS so that it can always neutrally damage something
  • Metronome & mirror move will not increment PP if the user is transformed
    • This prevents adding PP to hidden dummy moves that prevent a pkmn from going into Struggle
    • This also prevents Disable from freezing the game by targeting a dummy move
  • Mirror Move is checked against partial trapping moves in a link battle to prevent desync
  • Bide's accumulated damage bytes are now both set to zero on an enemy faint in order to prevent desync

  • Trapping effects only clear the hyperbeam recharge bit on a hit, preventing its automatic use on a miss
  • Trapping move PP can no longer underflow due to an opponent switching pkmn

  • Breaking a substitute does not nullify explosion/self-destruct, hyper beam recharge, or recoil damage
  • Hyper beam must recharge if it knocks out the opposing pkmn
  • Bugfixes involving Counter:
    • works against BIRD type, which is now typeless and assigned only to STRUGGLE
    • To prevent desync, pressing B to get out of the move selection menu zeros-out the ram location for selected move & move power
    • last damage dealt is zeroed in these cases (also fixes some issues with Bide):
      • it's the start of the round without a trapping move active (fixes most issues since Counter always goes second)
      • player/enemy pkmn is fully paralyzed or after hurting itself in confusion
    • Crash damage from jump kicks and pkmn hurting itself cannot be Countered
  • To prevent infinite loops, Rage ends after 2 to 3 turns (attack boosts are kept)

  • Stone evolutions cannot be triggered via level-up anymore

• Audio fixes

  • Fuschia gym plays the correct sfx when getting the TM from Koga
  • Vermilion gym plays the correct sfx when getting the TM from Surge
  • Restored sfx for getting a badge
    • A sfx is supposed to play when getting a badge, but not for all gym leaders and the sfx used is inconsistent
    • Looks like the idea was dropped in development due to issues with having separate audio banks
    • However, there is a unique unused sfx in the battle audio bank that signifies getting some kind of important item
    • This is likely what was going to be used for getting a badge at some point, and it has been restored

  • Additionally, every pokemon in the enemy roster is scored
    • based on various criteria to determine which mon gets sent out
    • score might dictate that the current mon is the best choice and abort switching
    • an enemy mon is flagged when sent out; non-volatile (except sleeping) status or low hp cannot initiate switching
    • enemy mon that is recalled back due to a super effective move is flagged; it is demerited from being switched-in
    • switch flags are all cleared when player sends out a new mon since the situation is now different

• Trainer AI battles now track which enemy pkmn have already been sent out, so allows for new functionality:

  • Trainer pkmn DVs are remembered between switching, and new ones won't be generated on every send-out
  • Trainer pkmn can now have stat experience assigned to them that is scaled to their level
  • These are real DVs and statEXP values that utilize the existing enemy party_struct which is normally unused by trainer AI

  • Changed based on user feedback since many trainers now try to switch

• Adjustments to learnsets and base stats

  • Mewtwo can learn Swift by TM

  • Improved exp calculation for developers who want a level cap between 101 and 255
    • EXP calculation routine now does math in 4 bytes instead of 3 bytes
    • Exp calculation result is still capped to 3 bytes regardless of level cap to prevent overflow
    • The byte cap on the exp result means that certain growth rates may have a level cap
    • For example, the "slow" growth rate is theorized to cap at level 237
  • Trainer battle prize money uses 3 bytes instead of 2, lifting the 9999 cap on winnings
  • Adjusted daycare to allow exp values over $500000
  • Allow up to 8 digits when displaying experience on the status screen
