For an explanation of what this is and how to use it, or to download a release, check its website.

This repository houses the full source code of DynRPG. If you are an end-user, get the release linked above instead.

• patch: Contains the source code of the RPG_RT patch (written in assembly).
• sdk: Contains the header files and documentation of the DynRPG SDK (written in C++).
• library: Contains the source code of the DynRPG library (written in C++).
• loader: Contains the source code of the loader DLL (written in FreeBasic).
• patcher: Contains the source code of the patcher tool (written in FreeBasic).
• dyndemo: Will contain an RM2k3 project as test environment for the patch and loader, will contain the patched RPG_RT and the loader binary.
• htmlhelp: Will contain the HTML Help Compiler.
• docs: Will contain HTML docs.

• Create an RPG Maker 2003 v1.08 project in a new folder dyndemo. You will test the patch and its functions here. The base version of the RPG_RT.exe can be found here.
• Install OllyDbg v1.10 and the MUltimate Assembler plugin. Also check out this answer in case you run into a problem with “Single-step event at ntdll” events. Add 0EEDFADE to the allowed exceptions list to avoid breaking unnecessarily (for example when pressing F12).

1. Load dyndemo\RPG_RT.exe into OllyDbg. You can specify command line arguments TestPlay ShowTitle Window for easier testing. If you have already loaded it and worked on it before, make sure to rewind it using Ctrl+F2 before saving changes (because further changes may have been made at runtime which you don’t want to include in the patch).
2. Press Ctrl+M to open MUltimate Assembler.
3. If you do this for the first time, right-click the tab bar and use the “Load from file…” option to load patch\patch.asm.
4. Click “Assemble” to apply the patch.
5. Make sure you are in the code segment - if not, press Ctrl+G and enter 401000.
6. Right-click assembly code in the CPU window and select “Copy to executable” => “All modifications”.
7. Right-click the file window contents and select “Save file”.
8. Save to RPG_RT2.exe.

This will create a patched RPG_RT binary dyndemo\RPG_RT2.exe.

• Install FreeBasic. Known working version is 1.03.0 but newer versions may work as well.
• Install FBEdit to open the .fbp project files.
• Test project in dyndemo must exist (see patch building prerequisites above).

1. Open loader\dynloader.fbp in FBEdit.
2. Select target Windows dll and hit F5 to compile.

This will create a loader DLLdyndemo\dynloader.dll.

• Install MinGW with GCC 5.3.0. Using a different version may require tweaks to compiler flags and/or modifications of __asm statements to work properly!
• Install CodeBlocks (10.05 is known to work) and make sure it is configured to use the correct GCC version.

1. Open library\DynRPG.cbp in CodeBlocks.
2. Select target Release and Ctrl+F9 to compile.

This will create a static library sdk\lib\libDynRPG.a.

Note: To build plugins using the DynRPG development environment, all you need to do is adding (DynRPG repo path)\sdk\include to your include search paths and (DynRPG repo path)\sdk\lib to your library search paths in the plugin project. If you then set the build output as (DynRPG repo path)\dyndemo\DynPlugins\your_plugin.dll, you can immediately test the plugin together with the dev version of DynRPG.

• Install FreeBasic. Known working version is 1.03.0 but newer versions may work as well.
• Install FBEdit to open the .fbp project files.
• Unpatched file dyndemo\RPG_RT.exe, patched file dyndemo\RPG_RT2.exe and loader dyndemo\dynloader.dll must exist (see instructions to build the patch and the loader above).

1. Open a command prompt and go to directory patcher.
2. Run hpdpa dynrpg.txt to create dynrpg.hpd.
3. Open patcher\dynrpg_patcher.fbp in FBEdit.
4. Select target Windows GUI and hit F5 to compile.

This will create a patcher binary patcher\dynrpg_patcher.exe.

• Install Doxygen, but get version 1.7.6.1 - there is no guarantee newer versions are compatible.
• Install HTML Help Compiler into a new directory htmlhelp.

• Open a command prompt and go to directory sdk\include\DynRPG.
• Run doxygen doxygen.cfg.

This will create HTML docs in docs\html and a CHM file in sdk\dynrpg.chm.
