*? GDA Creator Professional Edition (English version)
GDA Creator Professional Edition (GDAC2) is a tool to edit GDA file. You can also edit DTX file, and other BMS-like format file if you add plug-in file (lane script file).
The original Japanese version is at the J.T.'s web site.
Here is an English version, hacked by me (yyagi; Q&A staff). The base version is 0.24 (the latest one), and translated not only menus, but also dialogs and help files.
I've taken permission from J.T. (original GDAC2 author) to distribute English version here.
*? DTX Creator (English version)
DTX Creator (DTXC) is a tool to edit DTX file.
The original version supports both English and Japanese. You can download it from DTXMania download page.
To work DTXC, you have to install latest DirectX 9.0c.
.NET Framework 2.0 (or above) and Managed DirectX(MDX) 1.1. To install both of them, you have to follow the steps below (don't change the order!)
Install .NET Framework 2.0 (or later) via Windows Update. On March 1st 2009, .NET Framework package is shown on the Windows Update (Custom Install) as "Microsoft .NET Framework 3.5 Service Pack 1 and .NET Framework 3.5 Family Update (KB951847) x86" .
Install latest DirectX via Web Installer. (You must use Web Installer. Don't use redist package.) Moreover, you should also download DTX Viewer (DTXV) to use preview feature. (Current DTXC archive includes DTXV.exe.)
*? XaWrapper (English version)
XaWrapper is a GUI front-end wrapper for xa.exe. Xa.exe is a converter between wav and xa file.
(However, note that current DTXMania recommends to use OGG file, in place of xa/mp3 files.)
The distribution of English version is permitted by maruru.
You should also download xa.exe(1035) to use XaWrapper.
And you can read usage about XaWrapper.
*? xadec.dll library (English documentations)
xadec.dll is a library to handle with xa file. It is used in GDAC2 / DTXC / DTXMania etc.
The original one is made by Shin'ichi Nakamoto (the author of BandJAM), and I (yyagi; Q&A staff) add English docmentations.(1149)
