(must be the first line of the .rc file)

- New folder "savestate" for all save of SAVE STATE
- Fix save config file "gngeorc" on folder "conf", now writing correctly your saved prefs.
- changed a text on error request
- Fix and write a new code -> prefs config for individual game and add new PATH on prefs (confpath:), new global prefs for individual game "gngeogamerc".
change in 0.8.1 MORPHOS First release (code name "NG") By peponas and HunoPPC
-Fix lib�ration ressource
-Fix save all config, writing new routine
-Fix all error on libzip
-Full support render software, no support opengl render.

- Copy the folder Gngeo in your Emulation section, start the executable in the shell with your command, use version with native GUI , or use NeoGUI 51.4 (minimum) on http://os4depot.net/. (important delete your OLD prefs for NeoGUI and reboot your "miga" please).
-NeoGeo BIOS files are required, Copy neogeo.zip and uni-bios.rom BIOS on "bios" dir
=> required on the neogeo.zip
- NeoGeo ROMS files are required, Copy your all roms on "Roms" dir (for better compatibility see recent install roms from MAME World)
- Launch, choice your rom and enjoy
IMPORTANT: YUV, OpenGL and OpenGL2X don't support effect's (very slow) use effects with soft blitter please.
Options "save state" and "load state" are experimental that can crash the machine.

add -h after executable for look options:
--68kclock=x Overclock the 68k by x% (-x% for underclk)
--autoframeskip Enable auto frameskip
--bench Draw x frames, then quit and show average fps
-B, --biospath=PATH Tell gngeo where your neogeo bios is
-b, --blitter=Blitter Use the specified blitter (help for a list)
--country=... Set the contry to japan, asia, usa or europe
--dump Create a gno dump in the current dir and exit
-D, --debug Start with inline debuger
-e, --effect=Effect Use the specified effect (help for a list)
--forcepc Force the PC to a correct value at startup
-f, --fullscreen Start gngeo in fullscreen
-d, --gngeo.dat=PATH Tell gngeo where his ressource file is
-h, --help Print this help and exit
-H, --hwsurface Use hardware surface for the screen
-I, --interpolation Merge the last frame and the current
--joystick Enable joystick support
-l, --listgame Show all the game available in the romrc
--libglpath=PATH Path to your libGL.so
-P, --pal Use PAL timing (buggy)
--p1control=... Player1 control configutation
--p2control=... Player2 control configutation
--p1hotkey0=... Player1 Hotkey 0 configuration
--p1hotkey1=... Player1 Hotkey 1 configuration
--p1hotkey2=... Player1 Hotkey 2 configuration
--p1hotkey3=... Player1 Hotkey 3 configuration
--p2hotkey0=... Player2 Hotkey 0 configuration
--p2hotkey1=... Player2 Hotkey 1 configuration
--p2hotkey2=... Player2 Hotkey 2 configuration
--p2hotkey3=... Player2 Hotkey 3 configuration
-r, --raster Enable the raster interrupt
-i, --rompath=PATH Tell gngeo where your roms are
--sound Enable sound
--showfps Show FPS at startup
--sleepidle Sleep when idle
--screen320 Use 320x224 output screen (instead 304x224)
--system=... Set the system to home, arcade or unibios
--scale=X Scale the resolution by X
--samplerate=RATE Set the sample rate to RATE
-t, --transpack=Transpack Use the specified transparency pack
-v, --version Show version and exit
--vsync Synchronise the display with VBLANK
--z80clock=x Overclock the Z80 by x% (-x% for underclk)

All boolean options can be disabled with --no-OPTION
(Ex: --no-sound turn sound off)

Helper Option:


Enable auto frameskipping. The program will determine the best frameskip value to avoid lagging the gameplay on a machine that is too slow to emulate at full speed.


Use the specified blitter. -b help will provide a list of available blitters. soft, opengl, and yuv are typical choices.


Set the country code to japan, usa or europe


Enable gngeo's internal debugger, for hacking, cheating, or fixing bugs.


Use the specified video effect. -e help will provide a list of available effects.


Start gngeo in fullscreen mode.


Use a SDL hardware surface for the emulator's video. This can improve performance if your video hardware/drivers are fast.


Enable interpolation from one frame to the next. This can make the display look "smoother", but has a performance penalty.


Enable joystick support.


Use PAL timings. This currently has bugs.



Player 1 and Player 2 keyboard and joystick mappings, respectively. (need more details)
exemple: --p1control=A=K122,B=K120,C=K97,D=K115,START=K49,COIN=K51,UP=K273,DOWN=K274,LEFT=K276,RIGHT=K275,MENU=K27,UP=J0a0,DOWN=J0a1,LEFT=J0A0,RIGHT=J0A0,A=J0B3,B=J0B2,C=J0B1,D=J0B0,COIN=J0B8,START=J0B9,HOTKEY1=J0B10,HOTKEY2=J0B11
IMPORTANT: For your prefs "gngeorc" change this parameters please:
for joystick: J=joystick 0=number of joystick A=analogic H=digital 0=the hat (important: for inverse the fonction is "a" and not "A")
For keyboard is letter K


Enable the raster interrupt. (need more details)


Give the path to locate the ROM collection. The default is to look in PROGDIR:Roms/, but your ROM collection is most likely not there. :)


Give the path to locate the CONF collection. The default is to look in PROGDIR:conf/, but your CONF collection is most likely not there. :)


Enable sound emulation.


When the emulator is started, show a frames-per-second count. This can be used to gauge a baseline performance for the emulation.


Enabling this option will cause the emulator to give up time to the system when it is idle. It can incur a performance penalty, but can also make the emulator "nicer" to the rest of the system.


This option allows you to set the type of the emulated system to home or arcade, depending on how you prefer to play your games. There are some differences in many games if they detect a home system instead of an arcade system.


Upscale the resolution by N. For example, if N is 3, the Neo-Geo output, which is normally 320x224, will become 960x448 (create new screenmode: MODE=640x480@60
MODE=848x480@60. You may encounter a mode which is not hardware accelerated when using this option.


Set the sound sample rate to N. N will typically be 11025, 22050 or 26000.


Use the specified transparency pack (need more details), The default is to look in PROGDIR:/bld


Show summary of options.

F1 => Reset Neogeo Rom
F2 => Save screenshots on DIR "/PROGDIR/shots"
F3 => Test switch ON
F4 => Test switch OFF
F5 => Show fps ON:OFF
F10 => Autoframeskip ON/OFF
F11 => Sleep IDLE ON/OFF
F12 => Fullscreen / window mode
ESC => Menu with all prefs and choice
p => Pause game
