Doesn't work in WINE

[raymoo]

Concerto can open cccaster but isn't able to control it (or that's what it looks like). The cccaster window stays doing nothing and options can be selected normally like if I had launched it by itself.

Steps to reproduce:
0. Be using WINE on Linux

1. Run Concerto
2. Navigate and select Training
3. Wait for cccaster to open
4. Wait for something to happen

Here is the console output if it helps:

The warnings about gstreamer are because I disabled it to avoid a crash on melty title screen (which can appear briefly when cccaster launches melty)

Concerto is not compatible with WINE for the following reasons:

1. 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.
2. 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.

Both of these inconsistencies are grounds for bug reports to the WINE developers. Assuming nobody else does this before me I will do so with the release of a 1.0 version. However due to the nature of the problem (entirely missing features in WINE) I must close this as wontfix.
