There are many different patches, hacks and other dubious methods to add new functionality to RPG Maker. This page tries to list them.
Unofficial RPG Maker functionality can come in the following forms:
Changing harmony.dll allows to do external without modifying the main binary.
Harmony.dll is used for audio playback in RPG Maker 2000 (except Value!) and RPG Maker 2003 up to version 1.04. A patch, Force Harmony, was made to allow using Harmony.dll in newer RPG Maker 2003.
Supports: RPG Maker 2000 up to 1.10 (everything before VALUE!), RPG Maker 2003 up to version 1.04
To work with any other version, game needs to be patched with Force Harmony.
Executes scripts via the 'Play sound' command, and returns data through the midi ticks. Scripts are stored as sounds with .script.wav extension (the format of .script.wav is similar to INI files).
Also, allows to play MP3 (and theoretically also WMA) files by creating text files with .link.wav extension (a feature that was carried over from the older MP3 patch by Ineluki). Since this procedure is not managed by the game engine, music continues to play even if another track is started without correctly terminating the last one.
If FFDShow or something similar is installed, it may spam new symbols to task bar with every new file played until Harmony resets or game is closed.
The Key Patch is able to break system stability when starting a game if it gets prevented by a firewall to monitor key inputs.
Scripts allow to:
Since it allows to execute arbitrary exe files, it opened a way for a lot of smaller utilities.
Games using it: Detectivus Scitus
Skips the title screen of RPG Maker, allowing to create custom title screens. When used, the title screen will still show up, but is confirmed to start a new game instantly. To remove every disturbing detail, title and system graphic should be changed to empty black and the confirmation sound effect needs to be "(OFF)". It is recommended to use Better AEP (see below) instead.
Similar patch is available for RPG Maker 2003.
Supports: RM2k v1.07 and RM2k3 v1.08 (distributed as a modified binary)
Skips the title screen in a different more efficient way than Auto Enter Patch (see above) and allows to call load menu and exit game.
Stop Parallel Events is modified: When variable 3350 contains the value of 1, it calls a file menu in load mode. When it contains the value of 2, it exits the game. When it contains any other value (such as 0), Stop Parallel Events works normal.
Supports: RM2k v1.07 and RM2k3 v1.08 (distributed as IPS patches)
Allows to use the ID of picture stored in a variable.
If N+10000 is entered as a picture ID, the picture ID is read from variable N.
If N+50000 is entered as a picture ID, the picture ID is read from variable N, and the last 4 digits of variable (N+1) replace the last 4 characters of the picture name (for example, if TestTest.png is selected, and N+1 contains 5, then the filename will be Test0005.png).
Allows to use character graphics with arbitrary dimensions, as in newer RPG Maker versions. For this, Charsets must be named %XXYYName.png, where XX is width of one sprite divided by 4, and YY is height of one sprite divided by 4.
An adaptation of this script for RPG Maker 2003 v. 1.08 was made by Il Segugio.

Supports: RM2k v1.07 and RM2k3 v1.08
This patch allows to show pictures in battle. Patch is available in HPA format for HyperPatcher 2.
By default, pictures are not visible in the battle scene. Even they exist and can be manipulated through calling common events, they will become visible only after the battle ends. This patch allows to see all the pictures during the battle.

Supports: RPG Maker 2000 v 1.05 (distributed as modified RPG_RT.exe)
This patch fixed the 'Enter Hero Name' bug (the game freezed when executing this command) introduced in Don Miguel’s English translation.
Version 1 Supports: RPG Maker 2000 v. 1.05 (dropped with release of Ver2) and 1.07
Written in Assembler. Implements its own scripting language called DestinyScript for many kinds of data access and manipulation while game is running. Also comes with a patching tool that can adjust some details in the engine (repair broken EnterHeroName function, modify title screen or change order of blitting layers, for example chipset graphics above pictures,…).
Starting with version 1.05, RPG Maker 2003 doesn’t use Harmony.dll for music playback. The newer code allows to play MP3, but Harmony.dll was used not just for playing music — it was a DLL for executing custom code, as done by Ineluki's Key Patch (see above),
To allow using Ineluki's Key Patch and other Harmony Replacements, this patch changes RPG Maker 2003 v. 1.05 and above to use Harmony.dll. After this, RM2k3 v. 1.05 and above can no longer play MP3, since Harmony.dll doesn’t support MP3 (unless another patch like Disharmony is used).
Supports: RPG Maker 2003 v. 1.08
An ambitious project to create a C++ SDK for RPG Maker 2003. Allows to create many different plugins. Unfortunately, they are Windows-specific.

Some hacks are not presented as patches, but instead are done by every game creator manually, either with a hex editor, or with a specialised program.
The simplest type of hacks involves change of resources using Windows resource editors, such as Resource Hacker (proprietary freeware).
This way you can change an:
A custom EXFONT can be used by placing ExFont.bmp/.png in the games main directory. This will override the built-in ExFont.
Using custom fonts may be required if your language is not supported.
Note. Changing fonts doesn’t always require hacking an exe file. Sometimes games don’t change the font name, and just replace the default font (e. g. Czech game Broken Hearts comes with its own RMG2000 font).

Cherry’s Hyper Patcher (download; supports RPG Maker 2000 v 1.05, RPG Maker 2003 v1.04 and RPG Maker 2003 v1.08) allows to change a number of other things, mostly cosmetic:
Sometimes external programs are made to be called through the Ineluki's key patch (or other means?).
Description and download here: http://cherrytree.at/cms/download/?did=8
Provides programs ExitGame.exe, ExitSaveLoad.exe, Load.exe, Save.exe, SaveCounter.exe, SaveInfo.exe, SaveInfoSet.exe,
According to the documentation, it depends on the following:
Allows to make a screenshot and save it in the Pictures folder (converting to 256 colours).
