Status
Currently it is possible to extract a number of resources from both the USA and JPN version of Loom TG16/PC Engine, The resources built by this tool are based on the EGA version of Loom. It is also possible to play up until the difficulty selection screen in ScummVM, however the game will play further because the scripts are partially supported, but no graphics will be shown.
Things To Do
Figure out Graphics Format
- Some work has been done on this by Tomaitheo of Efnet #utopiasoft
- The tiles are compressed using RLE
Currently the graphics resources are extracted by extract_loom_tg16 however the resource format is unknown.
Figure out Sound Format
- The game makes use of sound effects as well as CD audio
- Currently the sound effect resources are not extracted by extract_loom_tg16.
Research needs to be undertaken into the location and format of these sound resources.
A good place to start is Efnet's #utopiasoft Also wikipedia has some information on the TG16 hardware here
