FCEU - Various problems

[Taldariner]

• [ ] Too high frame rate, because of which the speed of the game is huge, and it becomes impossible to play normally (the main menu barely responds to the keys at all).
• [ ] There is no sound in the game.
• [ ] Strange key bindings, for example in Contra the English "A" is both jump and shoot, i.e. A and B on the gamepad. But maybe it's a feature, not a bug.
• [ ] When launching the game, the cursor is not hidden even above the program workspace. But in general, it does not interfere much and is quite convenient, perhaps it should be done the same way in GameBoy and ZSNES (there the cursor is hidden even above the frame of the window, but the view is outside the emulator window).

It turned out that this is a very old port from the time of menuetlibc. This will probably no longer be supported. We need a newer port, either the same version or a higher one.

@mxlgv In this case, FCEU 0.98 is working well on my Windows system (KolibriOS port is based on 0.96, as I can understand, but I didn't manage to find it for Windows), but maybe it would be possible and reasonable to port even something newer, like last version of FCEUX. Would be great to have one emulator for both NES and SNES, but currently I haven't found anything suitable for this.

@Taldariner I did some further analysis and it seems the latest version of FCEUX is portable. You can follow the progress here: https://github.com/KolibriOS/fceux
