Video   :   TAXAN KY-3211
Sound   :   OKI M9810B
NVRAM   :   93C46 and battery backed RAM

Cartridge based system. Carts contain just some 16Mb flash eeproms.

Info from Tatsuya Fujita:

According to some news articles for the AOU show 2002 and 2003 the correct system name
is "Treasure Fall" (despite the cart label is "Treasure Hall").

--------------------------------------------------------------------------------------

To Do:

- Consolidate the sammymdl games in one memory map and run the BIOS without ROM patches
- Remove ROM patches: gegege checks the EEPROM output after reset, and wants a timed 0->1 transition or locks up while
  saving setting in service mode. Using a reset_delay of 7 works, unless when "play style" is set
  to "coin" (it probably changes the number of reads from port $C0).
  I guess the reset_delay mechanism should be implemented with a timer in eeprom.c.
- pyenaget intro: when the theater scrolls out to the left, the train should scroll in from the right,
  with no visible gaps. It currently leaves a small gap.
- tdoboon: no smoke from hit planes as shown in the video? Tiles are present (f60-125f) and used in demo mode.
- dashhero does not acknowledge the button bashing correctly, it's very hard to win (a slower pace works better!)
- dodghero and sushimar often write zeroes to 81XX1 and 00XX1 for some reason (maybe just sloppy coding?)

Notes:

- "BACKUP RAM NG" error: in test mode, choose "SET MODE" -> "RAM CLEAR" and keep the button pressed for long.
