Description:
Concerto is a launcher for the game Melty Blood Actress Again Current Code. It
interfaces with a CLI based interface known as CCcaster to allow for online
play, setting changes and to quickly launch the game and its various modes.
Currently when attempting to launch the game via Concerto (e.g. going into the
offline menu and attempting to launch the training mode) will cause Concerto to
pull up the CCcaster window but the game won't launch. CCcaster standalone
works just fine and even has functional online play out of the box with Wine.
The developer of Concerto has actually talked about this in a GitHub issue
located here https://github.com/shiburizu/concerto-mbaacc/issues/9 stating 
"Concerto is not compatible with WINE for the following reasons: 
Concerto depends on tasklist to monitor MBAACC & CCCaster processes. WINE does
not implement this at all in the main branch, and a staging version of this is
missing most of the functionality including some that we depend on.

ConPTY provides "pseudo terminals" to the pywinpty library that is used to
control CCCaster in the background. While WINE release notes mention ConPTY
support since 5.18 in practice it produces incorrect behavior: as noted in your
report a visible terminal is spawned and Concerto cannot send or receive
information to it."

For testing purposes the "community version" installer of the game that
optionally includes CCcaster and Concerto can be downloaded here.

Below I have attached an output of the console after running "wine
Concerto.exe". The last 3 lines are the error that occurred when I pressed the
"Training Mode" button
