Unfortunately, both WebOS Games Manager and preenv are unmaintained. There are a lot of ini files for WGM provided by users along this thread (now probably impossible to download again) that were never integrated into the application and these kind or bugs remain unfixed.

The preenv situation is even worse, as there is a version in the repos, the one with jflatt's patches for multitouch keymapping included by WGM and another one with partial support for HD games.
