* The original DOS demo is not supported yet, as it is based on very early version of engine, so many structures are different. Most of the resources have been mapped but they're still untested. The actors and objects list needs to be moved to our code. They've been found but not processed yet | |||
* There are currently two versions of ITE that are not uniquely identified: the Wyrmkeep "Win32 CD Version" and the original "DOS/Win32 CD Version", as the data files themselves are exactly the same, and only the original interpreter was different. When adding games, the user gets to do the disambiguation. If the user selects the "Win32 CD Version", the Dreamers Guild logo is not shown at the beginning of the introduction, and the credits are a bit different. In the Win32 CD Version, the file "graphics/credit3n.dlt" exists, but changes are needed to the Advanced Game Detector to detect the existence of this file. | |||

* The full game is partially working, but it's not possible to return to the character selection screen once a chapter is completed (or abruptly stopped by a wrong player option). ScummVM returns to the correct screen where AM is talking, but some variables are wrong and AM's speech is incorrect and the player is not taken back to the character selection screen. | |||

* Occasional graphics glitches | * Occasional graphics glitches in the Rats maze, when entering rounded doors which lead to another room. The 3D draw sequence is wrong, and the sprite is masked for the door sprite, ignoring the archway above the door. A screenshot showing the problem can be seen here: | ||

* Sometimes, incorrect music data is parsed to the MIDI parser, leading to a crash. This is occuring frequently in ITE, and rarely in IHNM. Perhaps it's related to some unhandled meta events. The crash always happens at sound/midiparser_xmidi.cpp in MidiParser_XMIDI::readVLQ2 at line 58.
