４． Build. (e.g. iOS)

$ ./libretro-build-ios.sh np2kai

'np2kai_libretro_ios.dylib' binary is outputed in libretro-np2kai

about libretro port

BIOS files locate in "np2" directory at BIOS directory (configured by RetroArch).
Configure file (np2.cfg) is made in "np2" BIOS directory.

NP2 menu is opened when F12 key or mouse middle button or joypad L2 button.
NP2 menu can FDD/HDD swap.

Mouse is cuptured (hidden/show toggle) by F11 key.

Mouse cursor is able to move with joypad when Joy2Mouse mode.
Switch Joy2Mouse mode in config.
D-UP/DOWN/LEFT/RIGHT: mouse move
B button: left click
A button: right click R button: inclease mouse speed

Keyboard is able to control with joypad when Joy2Key mode.
Switch Joy2Key mode in config.
D-UP/DOWN/LEFT/RIGHT: Arrow key or Keypad(2468) key B button: Z key
A button: X key
X button: Space key
Y button: left Ctrl key
L button: Backspace key
R button: right Shift key
Select button: Escape key
Start button: Return key

If you use 104 western keyboard,
to input underscore(_), press Shift+right Ctrl.

BIOS files

  • bios.rom
  • FONT.ROM (big letter)
  • itf.rom
  • sound.rom
  • (bios9821.rom or d8000.rom But I never see good dump file.)
  • 2608_bd.wav
  • 2608_sd.wav
  • 2608_top.wav
  • 2608_hh.wav
  • 2608_tom.wav
  • 2608_rim.wav

Setting to RetroPie

１．Install Japanese font. (umefont need SDL2 port only)

$ sudo apt-get install fonts-droid 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．Write & locate retroarch.cfg.

$ sudo vi /opt/retropie/configs/pc98/retroarch.cfg

# Settings made here will only override settings in the global retroarch.cfg if placed above the #include line

input_remapping_directory = "/opt/retropie/configs/pc98/"

#include "/opt/retropie/configs/all/retroarch.cfg"

４．Locate BIOS files.

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

５．Make shortcut to Japanese font. (SDL2 port only)

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

６．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

７．Add to "/etc/emulationstation/es_systems.cfg" writing.

$ sudo nano /etc/emulationstation/es_systems.cfg

...

    <platform>pc98</platform>
    <theme>pc98</theme>
    <directlaunch/>
  </system>
  <system>
...

８．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%"
default="lr-np2"

９．Launch ES and set "CARBON-MOD" to "THEME-SET".

Point of tuning performance NP2kai

  • CPU clock

Change "CPU Clock Multiplyer".

  • Memory size

Change "RAM Size".

  • Sound device

26K: for old games.
86: for newer games.

  • Sound Generator

fmgen: fmgen sound generator. Default: default sound generator.

Don't forget restart core.

  • How to set GDC 2.5MHz/5MHz?

1.Press End key(assigned Help key) + reset 2.Select 'ディップスイッチ２'(DIP switch 2)

  • How to key typing?

Unfortunery, libretro is unuseful for keytyping. Please use NP21/w.

  • How to use CD drive with MS-DOS 6.2?

Write follow to CONFIG.SYS.

LASTDRIVE=Z
DEVICE=A:￥DOS￥NECCDD.SYS /D:CD_101

And write follow to AUTOEXEC.BAT.

A:￥DOS￥MSCDEX.EXE /D:CD_101 /L:Q

Then, you'll can use CD drive as Q drive.

About network

From rev.7 we can use network.

NIC is follow spec.

MELCO LGY-98
IRQ:6
I/O:0x00D0
