Refactoring and bug fixes for bbusters and mechatt: (#7902)
* Moved sprite handling to a device. * Adjusted audio balance on mechatt (channel 0 was overpowering everything). * Adjusted priority handing on mechatt (planes now correctly rise from underground hanger on stage 3, train carts in later level). * Split driver in two, general refactoring etc. * Removed player 2 inputs from mechattu1 - it doesn't respond to them at all.

Mechanized Attack A8002 (c) 1989 SNK Corporation
|
||||
|
||||
Compared to Beast Busters (A9003), Mechanized Attack (A8002) is an
|
||||
earlier design, it only has one sprite chip, no eeprom, and only 2
|
||||
machine guns, but the tilemaps are twice the size.
|
||||
|
||||

|
||||
|
||||
Stephh's notes (based on the games M68000 code and some tests) :
|
||||
|
||||
2) 'mechatt'
|
||||
|
||||
- Country/version is stored at 0x06a000.w and the possible values are :
|
||||
|
||||
Value Country
|
||||
0x0000 Japan
|
||||
0x1111 World (value stored in the current set)
|
||||
0x2222 US
|
||||
0x3333 Asia? (it looks like Japanese text but some "symbols" are missing)
|
||||
|
||||
2a) Japan version
|
||||
|
||||
- All texts are in Japanese.
|
||||
- "(c) 1989 (Corp) S-N-K".
|
||||
- "Coin Slots" Dip Switch has no effect.
|
||||
- "Coin A" and "Coin B" Dip Switches are the same as in the World version.
|
||||
- Coin buttons effect :
|
||||
|
||||
* "Coin Slots" are ALWAYS considered as "Common" :
|
||||
|
||||
. COIN1 : adds coin(s)/credit(s) depending on "Coin A" Dip Switch
|
||||
. COIN2 : adds coin(s)/credit(s) depending on "Coin B" Dip Switch
|
||||
. COIN3 : NO EFFECT !
|
||||
. COIN4 : NO EFFECT !
|
||||
. SERVICE1 : adds coin(s)/credit(s) depending on "Coin A" Dip Switch
|
||||
|
||||
2b) World version
|
||||
|
||||
- All texts are in English.
|
||||
- "(c) 1989 SNK Corporation".
|
||||
- Coin buttons effect :
|
||||
|
||||
* "Coin Slots" Dip Switch set to "Common" :
|
||||
|
||||
. COIN1 : adds coin(s)/credit(s) depending on "Coin A" Dip Switch
|
||||
. COIN2 : adds coin(s)/credit(s) depending on "Coin B" Dip Switch
|
||||
. COIN3 : NO EFFECT !
|
||||
. COIN4 : NO EFFECT !
|
||||
. SERVICE1 : adds coin(s)/credit(s) depending on "Coin A" Dip Switch
|
||||
|
||||
* "Coin Slots" Dip Switch set to "Individual" :
|
||||
|
||||
. COIN1 : adds coin(s)/credit(s) for player 1 depending on "Coin A" Dip Switch
|
||||
. COIN2 : adds coin(s)/credit(s) for player 1 depending on "Coin B" Dip Switch
|
||||
. COIN3 : adds coin(s)/credit(s) for player 2 depending on "Coin A" Dip Switch
|
||||
. COIN4 : adds coin(s)/credit(s) for player 2 depending on "Coin B" Dip Switch
|
||||
. SERVICE1 : adds coin(s)/credit(s) for all players depending on "Coin A" Dip Switch
|
||||
|
||||
2c) US version
|
||||
|
||||
- All texts are in English.
|
||||
- "(c) 1989 SNK Corp. of America".
|
||||
- Additional FBI logo as first screen as well as small FBI notice at the bottom left
|
||||
of the screens until a coin is inserted.
|
||||
- "Coin Slots" Dip Switch has no effect.
|
||||
- "Coin A" Dip Switch is different from the World version :
|
||||
|
||||
World US
|
||||
4C_1C "Free Play"
|
||||
3C_1C special (see below)
|
||||
2C_1C "2 Coins to Start, 1 to Continue"
|
||||
1C_1C 1C_1C
|
||||
|
||||
It's a bit hard to explain the "special" coinage, so here are some infos :
|
||||
|
||||
* when you insert a coin before starting a game, you are awarded 2 credits
|
||||
if credits == 0, else you are awarded 1 credit
|
||||
* when you insert a coin to continue, you are ALWAYS awarded 1 credit
|
||||
|
||||
- "Coin B" Dip Switch has no effect.
|
||||
|
||||
- Coin buttons effect :
|
||||
|
||||
* "Coin Slots" are ALWAYS considered as "Individual" :
|
||||
|
||||
. COIN1 : adds coin(s)/credit(s) for player 1 depending on "Coin A" Dip Switch
|
||||
. COIN2 : adds coin(s)/credit(s) for player 2 depending on "Coin A" Dip Switch
|
||||
. COIN3 : NO EFFECT !
|
||||
. COIN4 : NO EFFECT !
|
||||
. SERVICE1 : adds coin(s)/credit(s) for all players depending on "Coin A" Dip Switch
|
||||
|
||||
2d) Asia? version
|
||||
|
||||
- All texts are in Japanese ? (to be confirmed)
|
||||
- "(c) 1989 SNK Corporation".
|
||||
- "Coin Slots" Dip Switch has no effect.
|
||||
- "Coin A" and "Coin B" Dip Switches are the same as in the World version.
|
||||
- Coin buttons effect :
|
||||
|
||||
* "Coin Slots" are ALWAYS considered as "Common" :
|
||||
|
||||
. COIN1 : adds coin(s)/credit(s) depending on "Coin A" Dip Switch
|
||||
. COIN2 : adds coin(s)/credit(s) depending on "Coin B" Dip Switch
|
||||
. COIN3 : NO EFFECT !
|
||||
. COIN4 : NO EFFECT !
|
||||
. SERVICE1 : adds coin(s)/credit(s) depending on "Coin A" Dip Switch

HIGHWAYMAN's notes:
|
||||
|
||||
after adding the mechanized attack u.s. roms I suspect that there is more than just a few bytes changed ;-)
|
||||
|
||||
----------------------------------------------------------------------------------------
|
||||
|
||||
Mech Attack Region code works as follows
|
||||
|
||||
ROM[0x06a000/2] = (data << 12) | (data << 8) | (data << 4) | (data << 0);
|
||||
|
||||
Country :
|
||||
- 0x0000 : Japan
|
||||
- 0x1111 : World (default)
|
||||
- 0x2222 : US
|
||||
- 0x3333 : Asia?

Emulation by Bryan McPhail, mish@tendril.co.uk
|
||||
|
||||
Like NeoGeo sprite scale Y line selection is from an external rom.
|
||||
|
||||
For 16 high sprites scale data starts at 0x3800 (9 scale levels)
|
||||
For 32 high sprites scale data starts at 0x7000 (17 scale levels)
|
||||
For 64 high sprites scale data starts at 0xa000 (33 scale levels)
|
||||
For 128 pixel high sprites scale data starts 0xc000 (65 scale levels)
|
||||
|
||||
0xe000 and up - possibly X scale data? unconfirmed
|
||||
|
||||
Sprites are also double buffered, and this seems to be performed
|
||||
by having two complete sprite chips that are toggled per frame, rather
|
||||
than just ram. Beast Busters has 4 sprite chips as it has two sprite
|
||||
banks.

|

Like NeoGeo sprite scale Y line selection is from an external rom.
|
||||
|
||||
For 16 high sprites scale data starts at 0x3800 (9 scale levels)
|
||||
For 32 high sprites scale data starts at 0x7000 (17 scale levels)
|
||||
For 64 high sprites scale data starts at 0xa000 (33 scale levels)
|
||||
For 128 pixel high sprites scale data starts 0xc000 (65 scale levels)
|
||||
|
||||
0xe000 and up - possibly X scale data? unconfirmed
|
||||
|
||||
Sprites are also double buffered, and this seems to be performed
|
||||
by having two complete sprite chips that are toggled per frame, rather
|
||||
than just ram. Beast Busters has 4 sprite chips as it has two sprite
|
||||
banks.
