mame/src/mame/drivers/magicfly.c
Aaron Giles 4e9be151f7 Renamed tilemap -> tilemap_t, as the name 'tilemap' is too commonly 
used for statics and structure members, and some compilers (esp. C++
compilers) don't allow that.

Memory Map (magicfly)
---------------------
$0000 - $00FF RAM ; Zero page (pointers and registers) (NVRAM).
($0D) ; Incremented each time a NMI is triggered.
($1D) ; In case of 0x00, NMI do nothing and return.
($11) ; Store lenghts for text handling.
($12) ; Store values to be written in color RAM.
($13 - $14) ; Pointer to text offset.
($15 - $16) ; Pointer to video RAM.
($17 - $18) ; Pointer to color RAM.
($19) ; Program loops waiting for a value to be written here through NMI (see code at $CA71).
($1E - $1F) ; Decrement. Looks as a sort of counter to temporary freeze graphics.
($22 - $25) ; 4-bytes buffer to compare/operate with other segments.
($2E - $31) ; 4-bytes buffer to compare/operate with other segments.
($32 - $35) ; 4-bytes buffer to compare/operate with other segments.
($39) ; Store bits 4, 5 and 6 of content to be ORed with $94 and written to input selector at $3000.
($3A - $3D) ; Store new read values from $2800 (input port) through NMI.
($3F - $42) ; Store old read values from $2800 (input port) through NMI.
($56 - $58) ; Store credits value (shown in the game under "Secondi").
($5A - $5C) ; Store bonus value (shown in the game under "Credits").
($5E - $5F) ; Store values to be written in video and color ram, respectively.
($63 - $63) ; Store position of marker/cursor (0-4).
($66 - $66) ; Store number of baloon to be risen.
($67 - $67) ; Program compare the content with 0x02, 0x03, 0x04, 0x05 and 0xE1.
; If 0xE1 is found here, the machine hangs showing "I/O ERROR" (see code at $C1A2).
($6A - $6B) ; Balloon #1 secondi (bet).
($6C - $6D) ; Balloon #2 secondi (bet).
($6E - $6F) ; Balloon #3 secondi (bet).
($70 - $71) ; Balloon #4 secondi (bet).

($94) ; Store bit 7 of contents to be ORed with $39 and written to output port ($3000).
($96 - $98) ; Store values from content of $2800 (input port) & 0x80, & 0x40, & 0x10.
($9B - $A8) ; Text scroll buffer.
$0100 - $01FF RAM ; 6502 Stack Pointer (NVRAM).
$0200 - $07FF RAM ; General purpose RAM (NVRAM).
$0800 - $0801 MC6845 ; MC6845 use $0800 for register addressing and $0801 for register values (see code at $CE86).
*** MC6845 init ***
Register: 00 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17
Value: 0x27 0x20 0x23 0x03 0x1F 0x04 0x1D 0x1E 0x00 0x07 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00.
$1000 - $13FF Video RAM ; Initialized in subroutine starting at $CF83, filled with value stored in $5E.
$1800 - $1BFF Color RAM ; Initialized in subroutine starting at $CF83, filled with value stored in $5F.
; (In 7mezzo is located at $CB13 using $64 and $65 to store video and color ram values.)
$2800 - $2800 Input port ; Multiplexed input port (code at $CE96).
; NMI routine read from here and store new values in $3A-$3D and copy old ones to $3F-$42.
; Code accept only bits 0-1-2-3-5 as valid inputs. For DIP switches, only bits 4-6-7 are valid.
; If an invalid bit is activated, it will produce an I/O error. (code at $CD0C)
$3000 - $3000 Output port:
Input selector, ; NMI writes the lower 4 bits to select input.
Counters. ; Bits 4-5-6 are used for Coin1, Coin2, and Payout counters.
Sound DAC, ; Bit 7 is used to transmit DAC data.
$C000 - $FFFF ROM space ; Program ROMs.
*******************************************************************************
After check the last bit of $1800, code jump into a loop ($DA30)...
BEHAVIOUR OF BOOT CHECK (magicfly):
1) Fill the video RAM with spaces (0x20), and color RAM with 0x15.
2) Check bit 7 of $1800 (video RAM, 1st offset) if activated.
3) If true, go to $DA30 (incremented fill infinite loop).
4) If not, fill the video RAM with spaces (0x20), and color RAM with 0x1F.
5) Check bit 7 of $1800 (video RAM, 1st offset) if activated.
6) If not, go to $DA30 (incremented fill infinite loop).
7) If true, returns and continue to NORMAL GAME.
Since bits 0-2 are for regular colors, seems that bit 3 in color RAM
(bit 2 for 7mezzo) is mirrored to bit 7 through a kind of device.
This is the only explanation I found to allow a normal boot, and seems to be
created as a protection method that don't allow owners to use a ROM-swap on
his boards, converting one game to another.

Game Notes
----------
Settings (valid for both games):
Press F2 to enter the input test (game should be without credits).
In the input test, you can exit with BET + DEAL, or access the bookkeeping
mode pressing BET + DEAL again. In the bookkeping mode keep pressed the PAYOUT
key and press BET to change the percentage (all books will be erased). Press
again BET + DEAL to exit to a quick RAM & sound test, and then to game mode.
* Magic Fly
How to play...
Insert coins to get credits.
Choose a balloon to raise, and select it with SELECT button. Bet on other balloons
using the SELECT/BET key (to bet 1 credit) or BETx10 (to bet 10 credits). Once done,
press the DEAL/LAST BET key to start the game. All balloons will explode revealing
numbers. The last one to explode will be the raised one. If your number(s) are higher
than the one hidden in the raised balloon, you'll win!
You can repeat the last bet pressing the DEAL/LAST BET key.
* 7 e Mezzo
This game is a sort of blackjack, but using a spanish cards set. The objetive is
to get 7 and half points (as 21 in blackjack). If you got more than 7 and half,
you're busted.
All cards have their own value, except for 10, 11 and 12 that are half point.
Special hands have their own price.
Sun 7 + sun king = 100 (by credit).
Any 7 + any king = 16 (by credit).
Any 7 and half = 8 (by credit).
Pass = 2 (by credit).
How to play...
Insert coins to get credits.
Bet using the BET button. Press DEAL to get the cards.
You can hit a new card pressing DEAL, or stop pressing STAND. The dealer will hit
cards to the maximum allowed. If you beat the dealer, you'll be asked to enter the
double-up game. Press DOUBLE to go on, or TAKE to get the credits.
In the double-up game, a covered card should be shown. Press BIG or SMALL to get
your chance...
