+ sfcbox.c
+ Preliminary driver file to handle emulation of the
+ Nintendo Super Famicom Box.
+
+The Super Famicom Box was used in hotels in Japan, with its installed Coin
+Box, makes it a pay-for-play system. It accepted 100 yen coins and gave 5
+minutes of playtime. The interesting part of this system is that it used
+special multicarts that contained two or three games as part of a larger Cart,
+for which the system holds two at once.
+
+The "To Do" list:
+-----------------
+-Main CPU banks cartridges via ports $c0/$c1
+-Consider moving the 3 cartridges of the slot 2 in a software list since they are interchangeable
+ (that's bs, since that pss61 should always be there anyway ... -AS)
+-Hook the z180 clone, the DSP 1A/1B and the Super FX
+-Add the possibly alternate revision of the attract ROM, with Kirby holding a coin
+ (unless it is unlocked with some DIP switch)
+
+Specific Model Number information

+PSS-001 - SUPER FAMICOM BOX - Main Unit
+This unit contains the three boards:
+the main board, the BIOS board and a passive board.
+
+1. The main board (MAIN 0871-100A) contains the Super Famicom core hardware as follow:
+CPU: S-CPU B (5A22-02 3MB 83)
+Video Controller: S-PPU1 (5C77-01 4AU 9L)
+Video Controller: S-PPU2 C (5C78-03 3MB 9V)
+Working CPU RAM: S-WRAM A (9442 T94 F)
+Sound CPU: S-SMP (SONY Nintendo'89 JAPAN 3WK4V)
+Sound DSP: S-DSP A (SONY'89 347AB7VZ)
+D/A converter: NEC D6376 - PDIF output model can be modified
+Slave (?) CPU: Hitachi 3M3R1 HD64180RF6X (Z180 clone)
+S-ENC A (9504 BA)
+MB90082 001 (9351 M02)
+
+2. The BIOS board (PU 0871-101) must be inserted into the main board.
+BIOS ROM: KROM 1, 512Kibit or KROM 2.00, 1024Kibit
+SRAM: SRM20257LM12 F27K 256 (S-MOS Systems) - SRAM accounting and control circuits are
+ self-diagnostic features that set time and operational status of the
+ game(s) that are installed.
+Battery: C2032
+Decoders: 74HC139A, 74HC237D, 74LS641, RTC S-3520CF (Seiko S3520CF2 C4446 J18)
+ and two other unreadable chips
+MB3790 (9413 M32)
+
+3. The passive board (GD 0871-103) to be inserted into the main board, has two cartridge slots.
+
+PSS-002 - SUPER FAMICOM BOX - Cartridge
+
+PSS-003 - SUPER FAMICOM BOX - Coin Box
+
+Software/Cartridge:
+The PSS-61 cartridge is required on the slot 1 for the machine to operate.
+The slot 2 may be free or contain PSS-62, PSS-63 or PSS-64 interchangeably.
+
+PSS-61 - SUPER FAMICOM BOX Commercial Regular Cart
+WARNING: This cartridge is required for the machine to operate.
+This game board (GS 0871-102) contains various chips in addition to the game ROMs:
+Attraction ROM: ATROM-4S-0, 4Mibit (is called Slave ProgramROM in BIOS menu ?)
+ Menu to select one of the 3 games (or 5, if a cartridge is inserted in slot 2)
+GameData ROM: GROM1-1, 256Kibit, most likely contains the graphics used by the attract menu
+ May also contain the extra text layers added to the game graphics
+Upper ROM: Super Mario Kart ROM (Nintendo), SHVC-MK-0, 4Mibit
+Upper ROM: Super Mario Collection ROM (Nintendo), SHVC-4M-1, 16Mibit
+Upper ROM: Star Fox ROM (Nintendo), SHVC-FO-1, 8Mibit
+DSP 1 B coprocessor: (DSP 1 A in earlier SFBOX units) it is needed to operate Super Mario Kart
+MARIO CHIP 1 coprocessor: Also known as "Super FX", it is needed to operate Star Fox
+Static RAM: 1Mibit
+Static RAM: 256 Kibit
+
+PSS-62 - SUPER FAMICOM BOX Commercial Optional Cart
+GameData ROM: GROM2-1, 256Kibit
+Lower ROM: New Super 3D Golf Simulation - Waialae no Kiseki (Waialae Golf) (T&E SOFT), SHVC-GC-0, 4Mibit
+Lower ROM: Super Mahjong 2 (I'MAX), SHVC-2A-1, 8Mibit
+
+PSS-63 - SUPER FAMICOM BOX Commercial Optional Cart
+GameData ROM: GROM3-1, 256Kibit
+Lower ROM: Super Donkey Kong (Nintendo), SHVC-8X-1, 32Mibit
+Lower ROM: Super Tetris 2 + Bombliss (BPS), SHVC-T2-1, 8Mibit
+
+PSS-64 - SUPER FAMICOM BOX Commercial Optional Cart
+GameData ROM: GROM4-1, 256Kibit
+Lower ROM: Super Donkey Kong (Nintendo), SHVC-8X-1, 32Mibit
+Lower ROM: Super Bomberman 2 (Hudson Soft), SHVC-M4-0, 8Mibit
+
+How does the Super Famicom Box operates
+---------------------------------------
+-Operate with a key, goes into BIOS, does automated checks, PSS-61 must be inserted for system to operate.
+-Goes into the attraction ROM, there is a graphical menu to select a game.
+ Apparently the menu graphics are imported from the GROMs.
+-Goes into selected game, can go back to attraction ROM menu.
