Atari ST Extra [013] Space Quest 4 DOS/VGA Talkie Intro in ScummVM on CT60 Falcon Roland MT32

Here is Space Quest 4 (VGA/Talkie) running in ScummVM/FreeMiNT on a CT60-equipped Atari Falcon connected to a Roland MT-32.  A mxing board is used to mix the digital sound with the MIDI audio.

The game is playable, but the Falcon does struggle to keep up a bit.  I think these problems mainly stem from how FreeSCI, and hence ScummVM, implemented the SCI engine.  The development philosophy behind FreeSCI was doing the reimplementation in a clean room like environment.  Since the implementation was done this way, and brought into ScummVM, data processing on this engine is a little heavier; even though this title, and many other SCI titles are still running in the low resolution of 320x200, with 256 colors.  The game should be perfectly playable, but cut scenes might have some hiccups.

For the brave, I will provide the binary that was used to capture the title in this video.  This binary was tested only under FreeMiNT, on an ext2 filesystem, compiled for the m68000 target, and absolutely every library and engine that was not needed was stripped out when configuring the build.  Only SCI games are supported.  No support will be provided for this build, and I do not know if it can even be used to complete a game yet!  Download here.

This video was captured on May 20, 2020.

This capture was played on an Atari Falcon equipped with a CT60 clocked at 66 Mhz and a SuperVidel
with the DVI and audio output being captured by a Startech USB3HDCAP.

Video was edited with Shotcut.
