Installation

Prerequisites

• A homebrew enabled Nintendo Switch console.
• At least one ScummVM supported game. The list of compatible games can be seen here: https://www.scummvm.org/compatibility/
• The page Where to get the games references some places where those games can be bought. Demonstration versions for most of the supported games are downloadable on https://scummvm.org/demos/

Installing

• The latest daily version of ScummVM for Switch is here (needs to be unzipped).
• Copy the scummvm folder to your SD card into the folder /switch/ so that you have a folder /switch/scummvm with scummvm.nro and other folders inside.
• Launch ScummVM using your favorite method to launch homebrew on the Switch

Configuring Games

The user manual describes how to add games to ScummVM and launch them: User Manual

short second finger tap while holding one finger	Move pointer to first finger position and right mouse button click
single finger drag	Move pointer directly with finger
dual finger drag (long second finger tap while holding one finger)	Move pointer while left mouse button is held down (drag'n'drop). The pointer directly follows the first finger. The drag is ended when the last finger is removed.
triple finger drag (long second and third finger tap while holding one finger)	Move pointer while right mouse button is held down (drag'n'drop). The pointer directly follows the first finger. The drag is ended when the last finger is removed.
Touch Controls (Touchpad Mouse Mode On):
Touch	Action
short single finger tap	Left mouse button click
short second finger tap while holding one finger	Right mouse button click
single finger drag	Move pointer indirectly with finger, pointer speed can be adjusted in control settings
dual finger drag (long second finger tap while holding one finger)	Move pointer while left mouse button is held down (drag'n'drop). The pointer motion is affected by the first finger. The drag is ended when the last finger is removed.
triple finger drag (long second and third finger tap while holding one finger)	Move pointer while right mouse button is held down (drag'n'drop). The pointer motion is affected by the first finger. The drag is ended when the last finger is removed.

Notes:

• Physical USB mice and keyboards work on the Switch and are supported by ScummVM. All keyboards work. Not all mice work. A mouse compatibility list is available here

• For multi-touch gestures, the fingers have to be far enough apart from each other, so that the Switch will not erroneously recognize them as a single finger. Otherwise the pointer will jump around.

• The touch control scheme can be switched in the main menu via "options->controls->touchpad mouse mode"

• When touchpad mouse mode is off (default), the touch controls are direct. The pointer always jumps to the finger.

• When touchpad mouse mode is on, the touch controls are indirect. The finger can be far away from the pointer and still move it, like on a laptop touchpad. The pointer speed setting in "options->controls" affects how far the pointer moves in response to a finger movement.

• The two finger drag is useful for Full Throttle to bring up the action menu, and in the menu to use the scroll bar in the game list. It works in the following way: holding down two fingers for a while initiates a drag'n'drop where the left mouse button is being held down. The first finger affects mouse motion during the drag, the second finger can be removed without affecting the drag. When the last finger is removed, the left mouse button is released and the drag is over. Note the second finger can be anywhere, it doesn't have to be close to the first finger, and it doesn't have to be put down simultaneously with the first finger, either.

• Typical usage of dual finger drag and drop in Full Throttle: Hold down one finger over an object. Then hold down a second finger somewhere on the screen for a little bit to initiate a dual finger drag. This brings up the action menu. Now let go of the second finger. The dual-finger drag continues since one finger is still down. Select an action with the first finger, and let go of the first finger to end the drag.

• There is also a three finger drag that causes the right-mouse button to be held down, instead of the left one. It might be useful for some games.

Building From Source

This port of ScummVM to the Switch is based on SDL2. It uses the open source SDK provided by devkitPro.

To build ScummVM for Switch:

• Obtain the ScummVM source code (https://github.com/scummvm/scummvm)

• Install the development tools for Switch following the official instructions (https://devkitpro.org/wiki/Getting_Started)

• Install libraries via

sudo -E dkp-pacman -S switch-portlibs

(or just `pacman -S switch-portlibs` if your system already includes pacman)

• Create a subdirectory somewhere outside the source folder for your ScummVM build and cd into it

• Execute the command

../scummvm/configure --host=switch --disable-libcurl

• Execute the command

make scummvm_switch.zip
