An emulator for the handheld gaming all-time bestseller.
Source Code released:http://www.thomasbertani.it/files/gnuboy-1.0.3.tar.gz
When removing the illume keyboard and installing the matchbox-keyboard (See also: Switching_Keyboards) it's possible to use the matchbox keyboard as input method (tested only on 2007.2, please verify). You need to create a ~/.matchbox/keyboard.xml file:
mkdir /home/root/.matchbox cp /usr/share/matchbox-keyboard/keyboard.xml ~/.matchbox/
PieterC created a profile to this file to change the layout to a game-boy lay-out (browsing the layouts can easily be done by pushing the > butten in the left bottom corner): add this to ~/.matchbox/keyboard.xml:
<layout id="GameBoy"> <row> <space width="500"/> <key> <default display="b" action="s"/> </key> <key> <default display="a" action="d" /> </key> <space width="300"/> <key> <default display="↑" action="up" /> </key> <space width="4000" extended="true" /> </row> <row> <key> <default display=">" action="modifier:layout"/> </key> <key fill="true"><default display="start" action="return"/> </key> <key> <default display="slt" action="space" /> </key> <space width="500" extended="true"/> <key> <default display="←" action="left" /> </key> <key> <default display="↓" action="down" /> </key> <key> <default display="→" action="right" /> </key> </row> </layout>
After untarring gnuboy to the openmoko, you can launch your favorite rom-file by running
./sdlgnuboy --fullscreen=0 --scale=2 pg.gbc
Some work has to be done...
Using the matchbox keyboard is clearly only a temporary solution: we need an input method that works out of the box. Since it uses sdl, we can check out the code of duke3d and simply port it into the put_events() function in the main.c. Some of us tried yet to implement this but no one succeeded to implement it, due to this issue.
When trying to implement the touchscreen as an input device for gnuboy, we won't be able to do multi touching (strike 2 buttons at a time). Since this is mandatory to some games (mostly fighting games) on the gameboy (color), we micht not use the touchscreen for all events. I propose to use the accelerometers as up down left & right, and use the touchscreen as A, B, start & select.
