Currently ScummVM support officialy two devices HP iPAQ h1910/h1915 and Asus MyPal 716, because port is designed to run in custom Familiar distribution. Unofficial support for this PDA's is on the wiki: iPAQ h191x and MyPal 716.
This distribution is based on Familiar branch from OpenEmbedded build development environment. It's customised and tuned for this two devices (currently only Opie supported).
ScummVM release has own snaphost of sources with patches and meta files needed to rebuild. It's because GPL license reasons. For version 0.9.1 is here.
Technicaly binary release of ScummVM may run on other Familiar Opie distributions and devices. But it will have lack of support and missing key features.
Main benefits over other devices is in modified SDL library. There are:
- normal keys mapping
- keymap to special actions like emulate right mouse button, key combinations, and others...,
- better handling graphics modes,
- downscaling from hires to lowres
- virtual keyboard
