* Figure out the resource types in the Turbografx/PC Engine version of Loom
 
* Add support for music and sound effects in the Apple II version of Maniac Mansion
 
* Add support for music and sound effects in the Commodore 64 versions of Maniac Mansion and Zak McKracken
 
* Add support for music and sound effects in the Macintosh version of Loom
 
* Add support for TFMX music format in Amiga version of Monkey Island 1 Check http://www.wotsit.org/search.asp?s=TFMX and http://freshmeat.net/projects/tfmx-play/ for music format details
 
* Add support for handling Kanji in FM-Towns games (foreground is rendered on a second plane at 640x480), text uses Shift_JIS encoding [implementation now that currently depends on font rom, not needing the rom would be preferable]
 
 
* Clean up class Gdi. This class right now mostly is about decoding various graphic formats. However some other functionality has crept into it, too. It would be nice if class Gdi would only contain the GFX decoding code, and nothing else (assuming that is feasible w/o too much trouble). OTOH, the code which is responsible for managing virtual screens, rendering virtual screens to the real display etc. could be grouped into a new class (e.g. VSManager or so).

* ADLIB: There seems to be some loop/repeat mechanism in old Adlib sound effects that we do not handle. [http://vogons.zetafleet.com/viewtopic.php?t=8644 This thread] has some discussion, and recordings. Two good examples are the door opening sound in Indy 3 and Monkey Island 1 (floppy), and the typewriter sound in Indy 3.

* ADLIB: We don't handle (global) music volume changes for adlib sounds in older SCUMM games. See {{BugTrack|num=1159581}}.

** Alternatively, change it to 5000 bytes to match the AdvancedDetector. This will affect far more games, so we'd end up with many obsolete MD5 ideas. But since we are pretty good at detecting SCUMM games correctly even without MD5, this shouldn't be so bad. However, some files might not be easily distinguishable with only the first 5000 bytes, need to check on that.

* Add support for non-interactive demo of Monkey Island 2. This can be done either by hacking the SCUMM loop and adding code to parse the existing 'demo.rec' file and re-injecting events in the event loop. Another possible approach would be to "specialize" the (future) events recording/playback code to deal with the original SPUTM .rec files.
