Windows Setup
Step 1
Change your system locale to Japanese. This requires you to reboot your computer.
If you do not change your system locale now, on the first step, you can ruin your entire installation.
Step 2
Download
You must be registered to see the links
and unpack it anywhere.
The zip should be 11.7MB.
It's recommended you use 7zip when unpacking files.
Warning: If you see a bunch of random junk in the filenames instead of Japanese characters you messed up and need to start over.
Step 3
You should now have a new folder, RTPセットアップ.
Inside the folder is RPG2000RTP.exe, run it to begin installing RTP.
The installation will be in Japanese, just keep clicking Next (Next has N> in it) until it's done.
Step 4
Download the latest version of the game.
The version number corresponds with the release date in a YYMMDD format.
You can always find the latest translated version in the pastebin on /vg/ or /h/ (look for /vhg/) or you can get it on Netty Folder from the Violated Heroine thread on Hongfire, or you can get an untranslated version and patch it yourself. It can generally be found on the japanese development forum or in the Netty Untranslated JP Releases.
If the archive you downloaded has a password, it will almost always be either "vh" or "nanako" without quotes.
Latest Version: 170318
Latest Translated Version: 170318
Once you've downloaded the game, unpack the files into a new folder.
There will be two executable files in the game folder, RPG_RT.exe is used to launch the game normally while RTP_RT_FatalMix2010.exe gives you additional commands.
