[GB] Shin Pokemon Red v1.24

Name: Shin Pokemon Red
Hacked by: jojobear13
Based on: Pokemon Red
Source Link: https://github.com/jojobear13/shinpokered
Description:
Hello, Welcome back to Pokemoner.com, and I’m Pokemoner. We will play Shin Pokemon Red or Blue by jojobear13! He tries to make Pokemon Red and Blue have Full Color, Fix bugs, improve AI trainer, and quality of life!

You can play as Boy or Girl in this game. More and More features you can read in my post. Anyway, It’s Completed in English. And now, Let’s play!

This is an enhancement ROM hack of Pokemon Red & Blue based on the Pret team’s pokered disassembly project. It is a mostly-vanilla hack that focuses on fixing game engine bugs and oversights from the original game. Additionally, trainer AI routines are improved and multiple quality-of-life enhancements have been added. It also acts as a kind of research-informed speculative work that presents an alternate interpretation of the games. Specifically, that being what the 2016 Nintendo Virtual Console re-release of Gen-1 Pokemon could have been.

It is the image of a glitch-free experience with player-friendly goodies and enhancements common to other modern remasterings.
The main purpose of the accompanying source code repository is to study, comment upon, and repair functional errors. It is important to record, for posterity’s sake, the methods used for restoring the game to an error-free state. Finally, the source code documents many differences and changes between the various Japanese and English releases.

Changeglog:
v1.23
New features exclusively for the master branch

Added nuzlocke mode

Hold SELECT and press START while on the bag menu or PC item box menu to auto-sort your items

The girl in Oak’s lab toggles a built-in randomizer for wild pokemon and your starters

Shuffles all pokemon that can be gained through walking, surfing, fishing, or from the game corner
If activated early enough, your starter pokemon options are shuffled as well
Randomizes using a saved seed value, so the shuffled order is always preserved between play sessions
A new random seed is generated upon each new game
There are three pokemon lists based on base-stat-total; A, B, and C tiers
Pokemon are only shuffled within their own list in order to maintain some modicum of balance
Scripted events are unaffected (gifts, in-game trades, static encounters, etc)
The game’s five legendary pokemon are excluded from randomization
The AREA feature of the pokedex automatically adjusts to show the new pokemon locations
Relocated one of the rocket grunts in celadon city, and he now sells bulk coins in the post-game

Trade evolutions no longer evolve at level 45

Trade evolutions now alternately evolve with a stone at a certain level with some new hinting NPC text

Kadabra
Use a moon stone at level 35
Hinted at by a NPC in the Pewter Museum that comments on the moon stone
Haunter
Use a thunder stone at level 35
Hinted at by the Lavender Town NPC that asks if you believe in ghosts
Graveler
Use a fire stone at level 35
Hinted at by a NPC on Cinnabar Island that talks about the mansion
Machoke
Use a leaf stone at level 35
Hinted at by a house NPC in Pewter City that talks about trainers teaching pokemon
A new NPC is in the north-south underground path for post-game mirror matches

Added a new Clause Brother for activating the Trapping Move Clause

A counter tracks if the player or the opponent use trapping moves like Wrap multiple times in a row
The counter increments only if a trapping effect move is selected to be used and it does not miss
After the counter has incremented to 2,
selecting a trapping effect move additional times will make the move to go 2nd in the round
this is the same priority as the move Counter
The counter only gets reset by switching or using a move that does not have the trapping effect
Reseting the counter will restore normal priority to trapping effect moves.
Added a fifth Clause Brother for the hyper beam clause; hyper beam will recharge if it KOs the opponent

A new drink stand on the route 19 beach sells vending machine drinks

Paras is gifted in the Route 2 house in case the player has no pokemon that can learn Cut

Unused beedrill trade has been restored and placed on Route 22

Added cloning and gene splicing

Added shiny mercy

When a player encounters an AI trainer shiny pokemon, the next wild encounter will be shiny
Side effect: Because trainer ‘mons can’t be shiny in regular difficulty, hard mode gives more chances to find wild shinies
Added new superboss at the seafoam shore (activated the same as the existing missingno fight)

Beating the seafoam missingo battle will certify you as a pokemon master on your diploma

Show Mewtwo to Mr. Fuji after beating the Elite 4 for a M.GENE

Added Bill’s secret garden behind his house

Put Mew in your top spot and show Bill to gain access
You will encounter the starter pokemon plus some other rarer pokemon
Shiny rates are 1-in-128 in this area
Added the MIST STONE

It will max-out all the stat exp of the lvl > 30 pokemon on which it is used
If all the stat exp is already at max, then it will set all the DVs to maximum instead
Defeat Lance with a Dragonite in your top spot and it will be given a catch rate of 168

Dragonite’s cry will play to confirm that this has happened
You can swap with another Dragonite in your party and listen to his after-battle text again to repeat the process
In this rom hack, a dragonite with this catch rate can be taught Fly via HM
This catch rate makes it hold a gorgeous box if transferred to Gen 2
Likewise, a dragonite holding a gorgeous box can learn fly if transferred into this rom hack
Implemented the old Down+B urban legend for pokeballs as a cheat code

The timing is different. You have to hold Down+B before the “[PLAYER] used [ITEM]” text finishes printing.
If successful, the ball tossed will be twice as effective as normal
Scaled back fishing, reduced its randomness, and made it more map-dependent

When using the old rod, press and hold B within about 1 second to always hook a magikarp

Improved itemfinder function

If an item is detected, it will play 1 to 3 chimes depending on how close it is (more chimes means closer to the item).
Lines will point in the direction of the item and flash with the chimes.
If the player is right on top of the item, no lines will show and the chime till play four times.
If the SELECT button is held while selecting to USE the itemfinder, then the original itemfinder function is used.
Added spaceworld-style trainer back sprites for consistency with the spaceworld ‘mon back sprites

Blue-JP has spaceworld-style back sprites, and a corresponding _origback patch has been added

The silhouette effect at the start of battle now displays when playing on a DMG gameboy

Recalibrated the experience gain at the daycare

the daycare lets you select moves to forget (if any) upon retreiving your pokemon

Retrieving a daycare pokemon that could have evolved via level will trigger evolution and learn any missed-out moves

Added a PC to the daycare

The daycare can now support two evolutions back-to-back

Teaching a TM as a field move (Dig/Teleport) no longer consumes the TM

Added visual indicator when swapping bag space

Tweaked a flag for shinies so it can be used as a debugging toggle

Organized the female trainer code to be activated via assembler tags in the makefile (for easy reference)

The Rival battles from the SS Anne through Pokemon Tower use super potions

The Rival battles after Pokemon Tower and up through Route 22 2nd-round use hyper potions

The Champion can use Full Heals in response to a status effect with a 25% chance

All trainers that use any kind of potion now use it with a 50% chance if their HP is low enough

Gym Leaders and mid-game Rival: below 1/5th total
Elite-4 and Champion: below 1/3th total
Added “The Shimmer”, a cheat feature for those who want viability when using certain low-regarded pokemon.

Toggled ON/OFF via the glass pokeball decoration in the rival’s house.
Pokemon Eligible: EKANS, CATERPIE, METAPOD, WEEDLE, KAKUNA, ZUBAT, PSYDUCK, PARAS, PONYTA, RATTATA, SANDSHREW, HORSEA, GOLDEEN, VENONAT, JIGGLYPUFF, ARBOK, BEEDRILL, BUTTERFREE, DITTO, FARFETCHD, GOLBAT, GOLDUCK, HITMONCHAN, LICKITUNG, ONIX, PARASECT, PINSIR, PORYGON, RAPIDASH, RATICATE, SANDSLASH, SEADRA, SEAKING, VENOMOTH, WIGGLYTUFF
The shimmer factor appears randomly and secretly, and is more likely to occur if you favor sending out eligible ‘mons.
The shimmer only manifests in ‘mons that are fully evolved, even if their pre-evos gained the secret shimmer factor.
When the shimmer manifests as a ‘mon gets sent out, that ‘mon gets a large boost to stats that are low-to-poor.
Technical details of the shimmer

A ‘mon eligible for shimmer that is sent out, either by player or enemy trainer, can get the shimmer factor.
The chance of getting the shimmer factor is 1-in-256 per send-out, rewarding a player that uses the ‘mon frequently.
The odds increase by +(1-in-256) per 2048 HP-StatExp that the sent-out pokemon has, encouraging player investment.
The shimmer factor is defined via the pokemon’s catch rate byte and is a value of $6D (held Miracle Berry in Gen-2).
The manifestation of the shimmer boosts one-to-four of a ‘mons unmodified stats.
If 3/8ths of an unmodified stat is less than the mon’s level, then the level value is added to that stat.
Stats that can be boosted are: attack, defense, speed, or special.

Enemy trainer level scaling biases the levels upwards for determining if a pokemon should be evolved
Strength hotkey requires facing a boulder to activate

If trainer scaling is on, you do not need to beat the 1st route 22 rival solo to get oak’s pokeballs

Female trainer can be activated by compiling with the _FPLAYER tag
TMs and HMs have their names determined by a list now
Fixed the wrong text pointer in vermilion city
New features and adjustments for both branches

Decoupled the harder difficulty to its own option bit and added the hard mode to the Lite branch

Pressing RIGHT while the cursor is in the BATTLE STYLE box will toggle the feature on/off
Contrasting this, pressing LEFT will let you select a battle style without toggling difficulty
Hard mode adjustments

Trainer stat exp has been re-scaled to be more realistic to attainable amounts per level

Critical hit chance in non-link battles use the Stadium 1 formula
Oak’s pokeballs will be upgraded to great balls if you beat the route 22 rival in hard mode

the start menu should close and you will hear a jingle confirming that the option reset worked
Debug Damage Display: Damage values will be displayed in battle as the UI updates as a debug cheat

Zero damage is not displayed
Damage is not displayed if either pokemon has zero HP remaining
Press and hold A+SELECT at the title screen to print the current RNG seed at the main menu

Switched over to the xor-shift method of RNG

If a zero-value random seed is detected, a new random seed gets generated using the original DIV register method

Gamma shader is now 23% faster thanks to optimizations by easyaspi314

The 60fps mode has better performance when playing in GBC-mode

Does this by using the double-speed feature of the GBC’s processor
Uses more battery as a trade-off
Improved fade-in and fade-out to black/white transitions when playing on GBC in 60FPS mode

Adjustments to multi-attack moves animation and messaging to improve battle flow

Multi-attack moves only print the effectiveness message after the last attack
2-attack moves do not print “hit 2 times” because its obvious that they always hit twice
Multi-attack moves hide the substitute sprite on the first attack and only restore it after the last attack
Twineedle is unaffected by all this due to how it swaps out its effect on the fly to a poison side-effect
Added optimizations to how OAM data is prepared so that overworld sprites wobble less

DelayFrame now manualy calls VBlank if it runs while the LCD is disabled

Added rom hack version tracking for save files

It’s a single byte in the save file that gets incremented each version
If the save byte does not match, the player is automatically warped back to Pallet Town

Removed the unused Ivysaur flag
The female trainer pic will now display on the diploma if applicable

AI can now handle fly/dig loops between the two pokemon

Adjusted some AI anti-spam for status moves

AI switch scoring applies an extra penalty for possibly switching a pokemon into a super-effective move

AI layer 1: If the player used and item or switched, AI is blind to the player’s sleep counter when considering dream eater

AI layer 3 will slightly discourage a move 25% of the time if it hits neutral with no STAB

Wherein a special move is being used on a ‘mon with greater attack than special stat
Wherein a physical move is being used on a ‘mon with greater special than attack stat
AI layer 3: The enemy is blind to the player type if considering a poisoning effect move and the player just switched

AI layer 3: There is a 90.625% chance per damaging move that AI is blind to player type after player switches

Prevents situations where AI will always pick the ideal move against a switch-in
‘Blind’ in this case means the AI will act as if the move being considered has neutral effectiveness
The AI might still favor a STAB move or a move that works better with its own stats
Withdrawing or depositing a key item from/to the player’s PC will default its quantity to 1

Item evolutions having a level requirement is now supported

Removed restore sfx from the AI x-accuracy item

Added the restore sfx to all AI hp-recovery items

Trainer switching (ai routine #4)can now be deactivated

This feature disallows enemy trainers to switch intelligently, just like in the original retail games.
With the cursor in the TEXT SPEED section of the option menu, press A to toggle this feature on and off.
the letters “x sw” will appear in the corner of the option menu to indicate that trainer switching is inactive.
Note that Jugglers are unaffected because their official gimmick is that they switch randomly.
