| 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.
| | PC-Engine/Turbografx Loom is supported since ScummVM 1.1.0. |
| 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.

| |
|
| === Figure out Graphics Format ===
| | *[[HOWTO-LoomTG16|How to rip a compatible ISO from your original PC-Engine/Turbografx Loom disc]]. This guide will show you how to rip an iso that you will be able to extract with the extract_loom_tg16 tool. |
| *Some work has been done on this by Tomaitheo of [irc://irc.efnet.org/utopiasoft Efnet #utopiasoft] | |
| *The tiles are compressed using RLE
| |
| **Format:
| |
| ***[http://gracesdisposal.bpweb.net/LOOM/TILE%20COMPRESSION/tile_compression.txt Single compressed tile.]
| |
| ***[http://gracesdisposal.bpweb.net/LOOM/TILE%20COMPRESSION/%23utopiasoft.EFNet.log Discussion of the compression.]
| |
| **Decoding:
| |
| ***[http://gracesdisposal.bpweb.net/LOOM/TILE%20COMPRESSION/loom-decode.cpp Some code for decoding tiles from hennymcc.]

|
| Currently the graphics resources are extracted by extract_loom_tg16 however the resource format is unknown.
| | *[https://www.scummvm.org/downloads/#scummvm-tools ScummVM Tools] This enables you to extract your resources from the games code ISO, You will want to use 'extract_loom_tg16'. |
|
| |
|
| === Figure out Sound Format ===
| | *If you are not using a platform mentioned on the downloads page, the source code for the extract tool is [https://github.com/scummvm/scummvm-tools here]. |
| *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 [irc://irc.efnet.org/utopiasoft Efnet's #utopiasoft.]
| |
| | |
| Also wikipedia has some information on the TG16 hardware [http://en.wikipedia.org/wiki/TurboGrafx-16#Technical%20specifications here.]
| |
| | |
| David Shadoff also has an interesting page with some sound related documents [http://pages.interlog.com/~daves/pce_info/info.html here.]
