implements support for extracting MIDPAK.AD from SETUP.SHR
this way the user isn't required to install the game and can just
use the files copied from CD-ROM.
Files inside SETUP.SHR were compressed using PKWARE data compression
library.
PKWARE decompression code based on information released by
Ben Rudiak-Gould in comp.compression on 13.8.2001
Miles Audio support is still disabled atm
and has to be enabled manually
set _nativeMT32, so that the MT32 XMIDI track set is getting used
and not the general MIDI one for MT32 Miles Audio playback.
This should solve the MT32 music issues, although this needs
to get verified in detail.
- renamed _MT32 to _nativeMT32
this name doesn't really make sense, because MUNT isn't a native
MT32, but the name is common to the other engines
- implement MT32 -> General MIDI mapping in case no MT32 is
available
- implement dialog screen, so that user is told about General MIDI
mapping and that it may sound awful
- Kirben told me that Elvira 2 is shipped with MUSIC.DRV and
INSTR.DAT file. Using MUSIC.DRV file makes the music work properly
I couldn't check, b/c I own none of these games.
- also commented out implemented bug of INSTR.DAT/MUSIC.DRV
This bug only affected the adlib drivers, so I guess we should
rather fix it instead of implementing the same buggy behavior
- both known variants are supported (INSTR.DAT + MUSIC.DRV)
- INSTR.DAT/MUSIC.DRV holds channel mapping, instrument mapping, etc.
- fixed bug inside S1D MidiParser, that ruined some instrument changes
0xFC header was seen as 2 byte header, but it's 4 bytes in Elvira 2
and 5 bytes in Waxworks / Simon 1 demo
- dynamic channel allocation for the MUSIC.DRV adlib driver is not
implemented atm, simply because at least the demos of Waxworks and
Simon 1 do not use this feature
- sound effects of Waxworks are not implemented atm
- note: the game "Altered Destiny" uses Accolade INSTR.DAT variant too
This probably affects the full version as well, but I haven't
verified that. Either way, the old code was obviously wrong while
the new makes it look right to me.
This is needed because the MIDI resources have their own loop flag
that overrides the global one. This makes a difference for games
that use MIDI both for music and sound effects, such as (limited
to?) the floppy version of Simon the Sorcerer 1.
