== General ==
== General ==
* Add proper support for the Accolade MIDI format uesd by the PC versions of Elvira 1, Elvira 2, Waxworks and Simon the Sorcerer 1 (DOS Floppy Demo). Currently invalid data is often passed through the MIDI parser, causing crashes.
 
* Use actual timer, for timer_callback() and timer_proc() code, to match exact timing of the original games.
== Personal Nightmare ==
* Add support for fading effects used for transitions between day and night, in the Amiga and Atari ST versions.
* Add support for palette differences (i.e. inventory icons), in the Amiga and Atari ST versions.
* Fix charset rendering to match original PC version exactly, squeezing character where required.
* Improve sound support, especially the handling of appended and queued sounds. The introduction sequence (in Amiga/AtariST ports) of [http://robertmegone.com/scummvm/demos/agos/pn-atari-ni-demo-en.zip demo] and full version, is the best point for testing.
* Using the 'Wait' command passes by far too quickly, and requires a work around. This problem occurs in the original game, when used on modern systems, due to the speed increase.


== Elvira 1 ==
== Elvira 1 ==
* Add support for the 'INSTR.DAT' Adlib instrument bank in the DOS version.
* Add support for EGA mode in the DOS version.
* Add support for drawing inventory arrows (hard coded image).
* Add support for music in Atari ST version (The format is unknown). The location of the music data is unknown.
* Add support for music in Atari ST version (The format is unknown).
* Add support for compression format used by music and tables files in the PC98 version.
* Add support for load/save screens.
* Add support for text format differences in Atari ST version.
* Fix background glitches on pause options in Amiga and Atari ST versions.


== Elvira 2 ==
== Elvira 2 ==
* Add support for the 'INSTR.DAT' Adlib instrument bank in the DOS version.
* Add support for music in Atari ST version (The format is unknown). The music data is stored in 'xtune.pkd' files, and not compressed.
* Add support for music in Atari ST version (The format is unknown).
* Add support for AdLib sound effects in the DOS version, which are stored in the 'mylib.fxb' file.
* Add support for sound effects (Adlib format?) in the DOS version, which are stored in the 'mylib.fxb' file.
* Fix the incorrect palette shown for interface (Lower parts) in Atari ST version. The correct palette is only shown when mixing options, restore options or save options are displayed.
* Fix highlighting of names through invertbox() sometimes been cut off, on the left side.


== Waxworks ==
== Waxworks ==
* Add support for loading room state resources from 'statelst' in PC version.
* Add support for AdLib sound effects in the DOS version, which are stored in the 'wax.fxb' file.
* Add support for loading and saving room state data.
* Add support for loading restart state in Amiga version.


== Simon the Sorcerer 1 ==
== Simon the Sorcerer 1 ==
* Add support for compression format (The format is unknown) used by the music in the Acorn disk version.
* Add support for [http://www.tribbeck.com/software/sonor/dtt/manual/appx_f.html  Desktop Tracker format] used for music in the Acorn disk version.
* Add support for [http://www.tribbeck.com/software/sonor/dtt/manual/appx_f.html  Desktop Tracker format] used for music in the Acorn disk version.

* Add support for music fade out in vc62_fastFadeOut() when changing locations.
* Fix minor glitch in the trail shown on the first map, when Simon is riding the Lion to the Goblin's Camp. The minor glitch occurs, as the next location starts blinking, slightly too much background is been restored for some reason.


== Feeble Files ==
== Feeble Files ==
* Add support for resuming position of last OmniTV video, after changing rooms.
* Fix occasional glitch when scrolling text in Oracle interface. See [[media:Oracle-glitch.png|this series of screenshots]] from the DIRECTIVE CHARTER article. (It happens in other places as well.) This is actually not a bug in the Simon engine, but rather a problem with the automatic calculation of dirty rects that we use to speed up full screen updates in some engines. Maybe the checksum algorithm is more likely to fail when there are only two colours involved?


* Currently, it is difficult to extract the Feeble Files .cab files for people on non-windows systems. Sadly, unshield [https://sourceforge.net/tracker/?func=detail&atid=399601&aid=1429549&group_id=30550 does not properly support the FF .cab files]. It would be nice if somebody could work on this. Maybe looking at the [http://programmerstools.org/node/122 i5comp source code] could help.
