Added unknown encrypted Royal Card. This game is running on Dino 4

Browse Source 
encrypted hardware, with a CPU+PLCC daughterboard. Decrypted pro-

 there's no valid code. Decoded and partially decrypted the graphics
 set. [Roberto Fresca, ANY]

Both games are promoted to working state, but flagged as 'game
unemulated protection' due to the lack of MCU emulation.

- Added unknown encrypted Royal Card. This game is running on Dino 4
encrypted hardware, with a CPU+PLCC daughterboard.
- Decrypted program address + data, but code still jumps into $48xx
range where there's no valid code.
- Decoded and partially decrypted the graphics set.
