Before this, MIDI playback was done by generating an SMF data stream,
which was then played using platform-specific methods (MCI on Windows,
MediaPlayer on Android, SDL_Mixer on other platforms). However, this
approach had an issue where the Y18 command (which reads loop counts and
markers) did not work correctly.
With this change, the MAKOMidi class now uses the RtMidi library to
control MIDI devices in real-time. This approach was used in the
original "System3 for win32", but has now been made cross-platform.
The dependency on RtMidi is optional. If RtMidi is not available at
build time or a MIDI device is unavailable at runtime, FM synthesis will
be used.
It can be activated by the -scanline command line flag, system3.ini, or
the menubar on Windows. Effective especially for games with 200-line
screen mode, such as Little Vampire and Intruder.
Stretch 512 horizontal pixels to 582 pixels. This is the same pixel
aspect ratio used by WebMSX.
Also set SDL_HINT_RENDER_SCALE_QUALITY to "linear", to improve the
scaling quality.
Some screens in Alice's Cottage 3 have menus implemented on the script
side. The script does not know the absolute position of the mouse
pointer (cursor movement is done by obtaining the relative movement
distance of the mouse), so the mouse pointer and the selected item were
often misaligned, and the cursor could not be moved by touch operation.
This adds a hack to the K3 command that emulates cursor movements by
absolute mouse pointer location.
Before this change, fade in and fade out was implemented using a
16-steps dithering pattern.
Now fading uses alpha-blending. It behaves like the PC98 version, where
fading was done by palette animation.
This reduces `sizeof(AGS)` by 1.2MB.
Some strings ("戻る" and "次のページ" in menu, character names in DPS)
are not included in game files but are hard-coded in the executable.
Now those strings can be overridden by adding [string] section to
system3.ini. For example, system3.ini for English translation of DPS
may look like this:
[config]
game = dps
title = D.P.S - Dream Program System
[string]
back = Back
next_page = Next Page
dps_custom = Custom
dps_linus = Linus
dps_katsumi = Katsumi
dps_yumiko = Yumiko
dps_itsumi = Itsumi
dps_hitomi = Hitomi
dps_mariko = Mariko
