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 structure of 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

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.

David Shadoff also has an interesting page with some sound related documents here.

Useful Tools

  • Mednafen is a fairly well equipped emulator with PC Engine support it also has a fairly fully featured debugger built in.
  • SVN Tools This enables you to extract your resources from the games code ISO, You will want to use 'extract_loom_tg16'.
  • If you are not using Win32, the source code for the extract tool is here.
