Touhou Patches Compilation

Hello everyone! In order to make all Touhou modifications and patches easily accessible without having to dig through multiple topics, I will compile all of them here, with a brief description of each item.
Because of the nature of patches, consider this topic to be a work-in-progress. I will appreciate it if people will also add patches to this topic, so I can put these into the OP.

NOTE: Make sure you are using the original (Japanese) version of the game! Some patches do not work with the Gensokyo hard-patched translations, and a few also don't work with THPatch soft-patch either.

Scorefiles

Scorefiles for Practice and Completion
Covers TH06 through TH15. No PC-98 or fighting games. Fully unlocked practice stages, extra stages and spell cards. Intended for use with practice patches.

Practice Patches & Boss Rush

SA Practice Patch (Riri)
In-game practice mode patch, allows you to start at any stage/midboss/boss attack and set miscellaneous elements (lives, power, graze, PIV, etc.).

UFO Practice Patch (Riri)
External practice mode patch, allows you to start at any midboss/boss nonspell or spell and customize lives, bombs, power, UFO, and PIV.

LoLK Practice Patch (Riri)
External practice mode patch, allows you to start at any boss nonspell or spell (midbosses excluded!) and customize lives, bombs, power, and PIV.
NOTE: Only works with v1.00a!

TD, DDC, and LoLK Boss Rush (Xirno)
Boss rush that removes all stage elements and only includes midbosses and bosses. Adjusted resources for balancing (full power fairy at the beginning of each stage).
Versions with or without midbosses as well as enabled or disabled bombs are included.
All in-game dialogue is removed. No need to Ctrl anymore!

MoF, SA, and UFO Boss Rush (Martin)
My very own boss rush patch of MoF, SA and UFO, as well as other games. Includes all midbosses and bosses. Keeps everything the same, including the ability to bomb.
Includes a version without midbosses.

SA Boss Rush (+ Satori Rush) (Drake)
Boss rush that removes all stage elements and most midbosses (only stage 5 and EX have midbosses). Bombs are disabled.
Some safespots are removed or modified, most notably Border of Wave and Particle and Ten Evil Stars.
Stage 4 includes ALL Satori spell cards. You can now face all 18 of Satori's recollections at once, with any shot!

UFO Boss Rush (Drake)
Boss rush that removes all stage elements and most midbosses (only stage 5 and EX have midbosses). Bombs are disabled.
Resources are adjusted to make up for the lack of UFOs.

PWG+VoWG Skip
Goes directly to said spells in MoF, stages 4/6.

PWG Loop
Infinitely iterating PWG.

PCB Boss Practice (Chirpy and rsy type)
Boss and midboss only patch for PCB.

MoF Boss Rush, MoF PWG/VoWG Practice, PCB Boss Rush, DDC Non-spell Practice (Chirpy)
In order:
Boss and midboss only patch for MoF. Faith dump fairy in stage 1 for all extends.
Patch that makes stage 4 and 6 practice skip straight to PWG (Aya survival) and VoWG (Kanako final), respectively.
Same as link above.
Allows you to practice any non-spell in DDC.

GFW Practice Patch (MegaPulse)
Patch that allows you to practice any segment of GFW you'd like, as this game lacks native practice options.

ISC Tool (some Chinese guy)
Tool that analyzes specific data of ISC, such as HP, graze, and number of bullets that can be canceled. Works on both gameplay and replays.

TD Arrange Patch (Modified Trance) (Nereid)
Patch that removes the invulnerability on trance, but allows you to trance at one spirit gauge or above instead of only the full gauge.

SpoilerAL (Japanese, not sure who made the English SSG's)
Practice tool that features a variety of useful stuff, such as spell card practice, boss only mode, and frame warping (for stage segments).
Requires the appropriate ssg files (see below).

SpoilerAL SSGs
(4.6 = frame warp, boss rush and spell practice, niL = cheats and ultra, LET = )

SpoilerAL SSG (nil)
Obtained from the ultra/memory modification site. For TH15 you'll need to use a hex editor for those memory codes since there is no ssg for that.

MoF SSG (Akaldar)
MoF practice stuff, one of them has dialogue, other does not.

IN nonspells patch

SSG for EoSD/PCB/IN/UFO/HSiFS

How to install Ultra

All ultra patches, up to TH14.3 (Japanese website)

No autobomb, but shot power is doubled.

Hard DDC (Chirpy)

Hard UFO (Chirpy)
UFO patterns reworked.

IN Double Stage 4 and Stage 6
Allows you to play both 4A/4B and 6A/6B in a single run.

HSiFS UltraB (mdude)
Increases the density of everything.

Japanese EoSD Ultra

Miscellaneous

THPatch (non-hardpatched languages, alternative portraits & skipgame patch)
AKA THCrap. Usually usable with any of the above patches. Does not modify your game files in any way, so do not worry about it messing up your game.
I highly recommend using this over Gensokyo hard-patches if you want to play the game in English or any other language (including troll/funny translations!).
Skipgame patch removes all stage portions and makes all boss attacks last less than 2 seconds.

PoFV Save Replay Crash Fix
PoFV has a bug that makes the game crash whenever you save a replay. Launching this alongside the game fixes that.

Vsync Patch (Adonis)
Removes input delay, allows you to customize in-game FPS (default is 60), fixes several bugs (PCB cherry display, MoF MarisaB 3-power unfocus, UFO 2.147b score display).

Input Display (Drake)
Shows your button presses. Works on both gameplay and replays.

No Hitbox Patch
Removes your visible player hitbox for TH07 onwards.

Real Hitbox Patch
Shrinks bullets to the size of their approximate hitbox area.

Touhou Launcher
Convenient way to open up any game.
