This is a port of Duke Nukem 3D, derived from Fabien Sanglard's
|
|
|
|
|
Chocolate Duke.

\subsubsection{Installation}
|
2019-06-16 18:23:49 +00:00
|
|
|
The \fname{.GRP} and \fname{.CON} files from an original installation
|
|
|
|
|
of the game must be placed in the \fname{/.rockbox/duke3d/} on your
|
|
|
|
|
device. The shareware files work as well, and are available at
|
|
|
|
|
\wikilink{PluginDuke3D}.

|
\subsubsection{Music}
|
|
|
|
|
In-game music will not work by default. For it to work, you must
|
|
|
|
|
install a modified Timidity patchset in the
|
|
|
|
|
\fname{/.rockbox/timidity/} directory on your device. There should be
|
|
|
|
|
a \fname{/.rockbox/timidity/timidity.cfg} file located in this
|
|
|
|
|
directory, along with the instrument files. You must edit the
|
|
|
|
|
\fname{.cfg} file so that all the path names are absolute (i.e. in the
|
|
|
|
|
form \fname{/.rockbox/timidity/instruments/*.cfg}).
|
|
|
|
|
|

|
|
|
As above, there is a free patchset available from
|
|
|
|
|
\wikilink{PluginDuke3D}.

\subsubsection{Video}
|
|
|
|
|
Rotation of the video output is possible by choosing the correct video
|
|
|
|
|
option in the in-game menu. If your device's display is normally
|
|
|
|
|
320x240, for example, choosing the 240x320 option will rotate the
|
|
|
|
|
screen 90 degrees, and the keymap will be updated as well.
|
|
|
|
|
|
|
|
|
|
\subsubsection{Caveats}
|
|
|
|
|
Sound effects, enabled by default, could have a detrimental effect on
|
|
|
|
|
playability on some devices. If you notice excessive lag, try
|
|
|
|
|
disabling sound.
|
|
|
|
|
|
|
|
|
|
The default button mapping may not be optimal for gameplay. Set a
|
|
|
|
|
different mapping in the ``Keyboard'' section of the game setup. Note
|
|
|
|
|
that not all keys are mappable on all devices.
|
|
|
|
|
|
|
|
|
|
Some devices will low memory or large GRP files will prevent the game
|
|
|
|
|
from completely caching the GRP file in RAM, which could lead to disk
|
|
|
|
|
reads during gameplay. This might cause the game to lag slightly when
|
|
|
|
|
it happens, which is normal. The game should resume in a second or so.
|
2019-06-16 18:23:49 +00:00
|
|
|
|
|
|
|
|
On other devices, large GRP files will render the game completely
|
|
|
|
|
unplayable. If this occurs, try using the smaller shareware GRP. If
|
|
|
|
|
this still fails, then please see Appendix \ref{sec:feedback} for
|
|
|
|
|
instructions to report a bug.
