/***************************************************************************
Driver file to handle emulation of the Tiger Game.com by
Wilbert Pol
Todo:
- Fix cpu and system problems that prevent the games from working.
Game Status:
- The DAC sound partially works, sound from ports 1,2,3 not done
- Inbuilt ROM and PDA functions all work
- On the screen where the cart goes into the slot there is video flicker
- Due to an irritating message, the NVRAM is commented out in the machine config
- Most of the cart games have severe video issues such as flickering and nonsense gfx
- Lights Out works
- Centipede works
- Wheel of Fortune 1 & 2 are working.
- Frogger works, but it is difficult to capture the female frog or the insect.
- Quiz Wiz works, but the end-of-round score doesn't show
- Jeopardy, playable with bad gfx
- Tiger Web Link & Internet, they look ok, obviously aren't going to connect to anything
- Williams Arcade Classics, Robotron works, the rest are no use.
- Monopoly is starting to show promise. It's playable but the video is terrible.
- The remaining carts are not functional to any useful degree.
