Setting to RetroPie

１．Install Japanese font.

$ sudo apt-get install fonts-horai-umefont

２．locate libretro & SDL2 port files.

$ sudo mkdir /opt/retropie/libretrocores/lr-np2
$ sudo cp np2_libretro.so /opt/retropie/libretrocores/lr-np2/
$ sudo mkdir /opt/retropie/emulators/np2
$ sudo cp np2_libretro.so /opt/retropie/emulators/np2/
$ sudo touch /opt/retropie/emulators/np2/np2.cfg
$ sudo chmod 666 /opt/retropie/emulators/np2/np2.cfg

３．locate BIOS files.

BIOS files locate in "˜/RetroPie/roms/pc98/np2/" directory.
and "/opt/retropie/emulators/np2/" too.

４．Make shortcut to Japanese font.

$ ln -s /usr/share/fonts/truetype/horai-umefont/ume-ugo4.ttf ˜/RetroPie/roms/pc98/np2/default.ttf
$ sudo ln -s /usr/share/fonts/truetype/horai-umefont/ume-ugo4.ttf /opt/retropie/emulators/np2/default.ttf

５．Add "carbon-mod". (Japanese nize)

$ git clone https://github.com/eagle0wl/es-theme-carbon.git
$ sudo cp -r ./es-theme-carbon /etc/emulationstation/themes/carbon-mod

$ sudo nano /etc/emulationstation/es_systems.cfg

...

  <system>
    <name>pc98</name>
    <fullname>PC-98</fullname>

７．Add to "/opt/retropie/configs/pc98/emulators.cfg" writing.

$ cd /opt/retropie/configs
$ sudo mkdir pc98
$ cd pc98
$ sudo nano emulators.cfg

np2="/opt/retropie/emulators/np2/np21 %ROM%"
lr-np2="/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-np2/np2_libretro.so --config /opt/retropie/configs/pc98/retroarch.cfg %ROM%"
