RVLM
rlvm is an open-source reimplementation of the VisualArt's KK's RealLive interpreter for GNU/Linux and macOS.
Download the latest version from Github. If you're an Arch Linux user, you can compile and install the program from the AUR.
Usage
Start the executable using an application launcher or from a terminal emulator with rlvm /path/to/game/. You also need to have a "msgothic.ttc" font file in the game or home directory. Otherwise, you'd have to specify a Japanese font file with rlvm /path/to/game/ --font font.ttc.
