OpenTTD port for Switch

This is my Switch port of OpenTTD, a re-implementation of Transport Tycoon Deluxe.

Port by @rsn8887, based on the Vita port by @angguss. I made some control enhancements and I also enabled sound on the Vita port, too (pull request to @angguss made).




Thanks

Thanks to the many developers who worked on this game.

Thanks to @angguss for his excellent Vita port, on which this Switch port is based.

Thanks to my supporters on Patreon: Andyways, CountDuckula, Jason Crawford, Greg Gibson, Jesse Harlin, Özgür Karter, Matthew Machnee, Milenko, and RadicalR.

Installation

  • Download (see assets below), and unzip openttd_switch.zip and copy the contents over to the /switch/ folder on your sd card, so that you have a folder /switch/openttd with many folders and files inside.

  • Use you favorite homebrew launcher to start the game. It comes with everything you need to start playing right away.

  • Note: This game takes quite long to load (~15 seconds). But it is worth the wait!

  • The public domain graphics and sound sets from www.openttd.org are included.

  • If you want the choice to also use the original dos game graphics and sounds, copy over the files

SAMPLE.CAT 
TRHCOM.GRF
TREND.GRF
TRTITLE.GRF
TRG1.GRF
TRGC.GRF
TRGH.GRF
TRGI.GRF
TRGT.GRF

from an original TTD game to /switch/openttd/baseset/.

  • To install the original music, copy over all files
gm/gm_ttxx.gm (xx are numbers)

from the folder gm from the original windows version of the game to /switch/openttd/gm/.

You then get the choice to select original dos graphics, sounds, and music when you go to the game settings dialog.

Controls

  • Left analog stick = mouse pointer control
  • D-Pad or right analog stick = scrolling the map.
  • A/right trigger = left mouse click
  • B/left trigger = right mouse click
  • Y = zoom-in
  • X = zoom-out
  • Hold ZL = speed up analog joystick mouse
  • Hold ZR = slow down analog joystick mouse, useful to precisely position the pointer
  • Minus = switch button mappings between two presets: ZL/ZR = slow/fast mouse and Y/X = zoom, or ZL/ZR = zoom and Y/X = slow/fast mouse
  • Double click A / double click right trigger over a text field = bring up on-screen keyboard
  • The touch screen is used for indirect mouse input, like on a laptop touchpad. Move a single finger to move the mouse pointer. Use short tap for left click. Hold a single finger while tapping a second finger for right click. Drag with two fingers to drag and drop.

Current Limitations

  • No network support

Building

libtimidity:

git clone https://github.com/rsn8887/libtimidity
cd libtimidity/src/
make -f Makefile.switch
cp libtimidity.a $DEVKITPRO/portlibs/switch/lib/
cp timidity.h $DEVKITPRO/portlibs/switch/include/
cp ../libtimidity.pc $DEVKITPRO/portlibs/lib/pkgconfig/

liblzo2:
Download https://www.oberhumer.com/opensource/lzo/download/lzo-2.10.tar.gz and extract, then

cd lzo-2.10
./configure CFLAGS='-fPIC' CXXFLAGS='-fPIC' --host aarch64-none-elf --prefix $DEVKITPRO/portlibs/switch/ --disable-shared --enable-static
make clean
make -j12
make install

liblzma:
Download and extract xz-5.2.4.tar.gz from https://tukaani.org/xz/ , then

cd xz-5.2.4
./configure CFLAGS='-fPIC' CXXFLAGS='-fPIC' --enable-threads=no --host aarch64-none-elf --prefix $DEVKITPRO/portlibs/switch/ --disable-shared --enable-static
cd src/liblzma
make clean
make -j12
make install

Then configure and build OpenTTD from my switch branch:

git clone https://github.com/rsn8887/openttd
git checkout switch
PKG_CONFIG_PATH=$DEVKITPRO/portlibs/switch/lib/pkgconfig ./configure --os=SWITCH --host aarch64-none-elf --enable-static --prefix=/opt/devkitpro --with-sdl="pkg-config sdl2" --without-fontconfig --disable-strip --without-threads --with-libtimidity --enable-debug=0
make -j12
cd os/switch
git clean -f
cmake ./ -D
make openttd_switch.zip

openttd_switch.zip can be found in cmake/
