# NETfishing for PortMaster

This package contains NETfishing \`${RELEASE_TAG}\`, exported from Godot 4.7.1
for 64-bit ARM Linux and wrapped for PortMaster.

## Installation

Install the complete \`netfishing.zip\` archive with PortMaster or HarbourMaster.
The package requires an ARM64 device, two analog sticks, GLIBC 2.28 or newer,
and the \`weston_pkg_0.2\` runtime.

Save data and device-local configuration remain under \`netfishing/conf/\`.
PortMaster launches use the light performance profile by default. Put the word
\`normal\` in \`netfishing/conf/performance_profile\` to opt a capable device
into the normal rendering profile. See \`netfishing/licenses/\` for bundled
credits and license information.

## Controls

NETfishing reads the handheld controller directly. PortMaster's system
force-quit chord remains available; this is Start+Select on most devices.
