The joyce-l10n-keyboard.patch is a patch to apply to the Amstrad PCW emulator
from John Elliott, Joyce.
This patch has been tested against Joyce v2.2.12. You need Joyce sources.
# Download Joyce Unix sources
wget http://www.seasip.info/Unix/Joyce/joyce-2.2.12.tar.gz
# Extract the Joyce archive
tar xzvf joyce-2.2.12.tar.gz
# Enter the directory
cd joyce-2.2.12
Copy joyce-l10n-keyboard.patch in the joyce-2.2.12 directory.
You then need to use the Linux patch command.
# Patch JoycePcwKeyboard.cxx
patch bin/JoycePcwKeyboard.cxx joyce-l10n-keyboard.patch
You can now proceed with the standard way of compiling under Linux.
sh configure.sh
make
sudo make install
Joyce considers the keyboard to be the default PC keyboard which causes problem with localized keyboards, such as french keyboard, when you use the localized version of PCW CP/M Plus or LocoScript in the emulator.
Joyce is not affected by the Gnome keyboard mapping. This means you usually
would have to use setxkbmap to have a correct keyboard mapping:
# Use the default PC keyboard layout
setxkbmap us
# Use the localized french keyboard layout
setxkbmap fr -variant oss
But setxkbmap works globally. You have to switch back and forth between the
layouts using command line.
The patch forces Joyce to use keyboard scancodes instead of SDL key symbols by providing a key map from scancodes to SDL key symbols.
