This application is designed to play games of the RPG Maker engine, but you can also use it to port games
rpgmaker-linux --exportthegame
but the porting code is outdated; I might update it later
Have you tried the installer, this command?
wget -qO- "https://raw.githubusercontent.com/bakustarver/rpgmakermlinux-cicpoffs/refs/heads/main/proversion/proversion_install.sh" | bash
----------------------------------
you can install from the archive, and then add your key to the file
"$HOME/.config/itchiokey.txt"
You can find the instructions on github
