The Ubuntu guide is probably better than doing this way. So even if you are on manjaro or Arch use the Ubuntu one.
Steps for playing Beatoraja on Arch Linux :
pacman -S java8-openjfx java-runtime-common jre8-openjdk jre8-openjdk-headless ca-certificates-utils
java -version (Needs to show openjdk version "1.8.0_***"OpenJDK Runtime Environment (build 1.8.0_232-b09)OpenJDK 64-Bit Server VM (build 25.232-b09, mixed mode) or similar)
pacman -S yay (use paru since paru succeded yay https://github.com/Morganamilo/paru)
yay -S ttf-monapo (Other fonts might break the GUI)
java -jar beatoraja.jar (OR java -Xms1g -Xmx8g -cp beatoraja.jar:ir/* bms.player.beatoraja.MainLoader OR run beatoraja-config.command using the terminal)
You NEED to install the Japanese font
You NEED javafx
You NEED to have the right java environment (archlinux-java fix) OR point to the right one inside the .command file
You DO NOT NEED to have any other java version
You NEED to install all dependencies that is requested
you NEED ntfs-3g or a similar program to use NTFS drives.
You CAN NOT use your Windows config file with Linux
You MIGHT NEED to enable japanese locale
un# ja_JP.UTF-8 UTF-8
(Save and Exit)
add a new line with : export LANG=ja_JP.utf-8
add a new line with : export LC_ALL=ja_JP.utf8 (they might do the same thing) (not needed anymore)
I highly recommend using gnome instead of KDE if you are having frame pacing issues.
If you decide to use KDE, make sure to install https://github.com/tildearrow/kwin-lowlatency
Since Kwin-lowlatency is dead please use Openbox/KDE (pacman -S openbox)
Gnome has problem with minimizing the game
When using KDE press alt+shift+F12 to disable the compositor and remove any stuttering or right click on program title bar -> More Actions -> Configure special windows... -> Add property -> search block compositing and then enable it. (only with xorg, wayland need compositing to display something (shit))
"java -jar beatoraja.jar -s" to skip beatoraja's control panel
add an alias to make a command and stop doing "cd /beatoraja/sh b*." everytime. search how to make an alias with zsh or bash on archlinux.
