Some minor game adjustments

At lower levels, the monkey throws barrels diagonally less often than before, at higher levels, he throws them diagonally more often than before.

In the second game stage, Mario walks slower against the direction of the conveyor belts.

The monkey "dance" at the end of the game has the same music as the arcade game.

An error in the sound of falling springs in the third game stage is fixed.

The game can now use the extended memory of the Didaktik Gama computer. It does the same thing as on Spectrum 128K, so the introduction and control screen appear before every new game.
