Rubik's Cube simulator

The program was originally written by me for 48K Speccy in 1998-1999.
In 2013, I fixed it for colour-per-pixel mode of ATM Turbo 2 compatibles
(featuring original colors of the toy).

There's nothing like 3D, it's totally sprite-based and hand drawn :)

Also in this fix:
- Removed annoying dot flashing on the left.
- Large holes appeared while rotating - redrawn.
+ You can change the music (anything compiled to #c000 with entry +5 or +6) - just replace the file
(GUITAR.C or rubmuz.C).
- The speed might be far too fast on modern machines, so, it's limited to 2 frames now.
+ Sources added.

48K version is recompiled with these fixes too.

H is help (in Russian). Remains untouched since 1999.
M toggles music.

Original music (GUITAR.C, linked to 48K version) by myself.
Alternative music (rubmuz.C, linked to ATM Turbo 2 version) by DAVOS/HorrorSoft/CPU.
