Ensure your DirectX End-User Runtimes and Visual C++ Redistributables are up to date. 3. Safety Warning

Ryuugames often uses internal codes (like "RY-XXXXXX") to catalog their library. To confirm what game you have:

If the game is made in RPG Maker, you may need to install the specific RTP version (e.g., VX Ace, MV) for it to boot.

Check the root folder after extracting for a Readme.txt or a .exe file.

If your .rar file is significantly smaller than the listed game size, do not run the .exe .

Many Japanese visual novels will not launch or will show "garbled" text unless your system locale is set to Japanese. Use a tool like Locale Emulator to right-click the .exe and "Run in Japanese."

Users on communities like r/PiratedGames have reported issues with "wrong" download buttons on the site leading to small .rar files (around 18MB) containing malware rather than the actual game (which is usually several GBs).
