Service Mode:
Service Mode reflects the local configuration after playback ends, not the recording. Service Mode is accessed by enabling the DIP Switch which can be toggled with the Service Mode Button (F2) followed by a reset thus cannot be recorded in an INP. Service Mode presents the configuration in read-only mode with interactive representations of the players' ships for movement directions and test descriptions for other inputs.

Default Settings:

From MAME 0.250 after enabling the DIP switch.

Note: the options for the 'Lives' dipswitch have not changed between 0.106 and 0.250: 10k / 20k / 30k / 40k and the rules of the existing two variations match the default 10k. MAME 0.106 awards an extra at 10K. I have not investigated the 0.146u4 fix to understand its effect beyond this matching of the rules - Barthax, May 2023.

Note: two ROM sets represented here with changeover at 0.139u2.

- 0.133u1: Renamed (gangwarb) to (gangwarsb).
- 0.139u2: David Raingeard added correct GFX roms for Gang Wars, renamed bootleg set as Euro set (and new parent), made note about bootleg GFX roms. Changed description of clone 'Gang Wars (bootleg)' to 'Gang Wars'. Renamed (gangwars) to (gangwarsu) and (gangwarsb) to (gangwars).
- 0.154: Jets and Layer added clone Gang Wars (Japan). David Haywood added Gang Wars (bootleg). Reinstated the bootleg, these 68705 instead of alpha MCU bootlegs might be interesting later down the line even if the main code is the same. Also one of our mask roms was bad, and the gangwarsu set should definitely have been using different roms for the gfx [David Haywood]. Added gfx2 rom ($200000) from clone (Japan) to Gang Wars. Added new gfx2 roms to clone (US).
- 0.156: Added SCREEN_RAW_PARAMS for Alpha 68k HW [Angelo Salese]. Changed VSync to 60.191409 Hz.
- 0.215: Added video\alpha68k_palette.cpp/h. Support for opaque tiles for V board, fixes title screen clipping effect in Sky Adventure. Also removed hack for the priest priority in level 1 in Sky Adventure, being a game original bug. Converted Alpha68k driver to snk68 sprite chip. Converted Alpha68k driver to a common palette device and decoded it with NeoGeo specs, causing more accurate colors especially visible on dithered backgrounds. Simulated screen blanking for Gold Medalist starter pistol shot on dash events [Angelo Salese]. Changed VSync to 59.185606 Hz.
- 0.221: Added DIP locations [Guru].

Rules: [no current tracks]

Service Mode:
Typical "Tecmo.cpp" driver hardware.
Service Mode reflects the local configuration after playback ends, not the recording. Service Mode is accessed during boot up by holding P2 Start button. DIP switches are shown during boot up beginning around frame 319 - this is the point at which to hold P2 Start button. Any changes to the DIP switches (via MAME UI) are immediately shown in the visual representation within the game.

ROM set changed: no
0.106-0.250: genix - "Genix Family"

MAME Bug Note:
- The game hanging is an interesting issue, the board owner has 2 copies of this game, one a prototype, on the final released version. The roms on both boards are the same, however the prototype locks up just as it does in MAME at the moment. The final board does not. It would appear the prototype board does not have the protection hardware correctly in place.

Service Mode is accessed via the DIP Switch which is toggled with the Service button (F2). A series of screens can be transitioned with the Test (9) button. The Game Options screen can be interacted with using P1 Start button for navigation and P2 Start button to change values.

Service Mode:
Typical Taito F2 BIOS.
Service Mode reflects the local configuration after playback ends, not the recording. Service Mode is accessed using Service button (F2) and then a reset must occur, thus cannot be recorded in an INP. A test screen appears initially and can be progressed with P1 Start button. The second screen is an input test screen with DIP switches shown in read-only binary form.

Note: Dump is a bit odd, 2 roms were identical, one rom needs to be loaded over the end of another as not to get corrupt text. I've asked for verification. Despite being in Italian this is a newer and noticably more complete version than the previous set, so I've made it the parent [David Haywood].

Service Mode:
Typical Kaneko 16-bit BIOS.
There are both hardware DIP switches & internal settings. Hardware DIP switches will reflect local configuration after playback, not the recording. Other relevant rules are covered by internal settings. If not shown during playback, use Service Mode to access after playback completed. Service Mode is accessed via the DIP Switch which requires a reset thus cannot be recorded to an INP anyhow. Navigation instructions are given at the bottom of the screen.

Default Settings:

gtmr

ROM set changed: no
0.106-0.200: gtmr - "1000 Miglia: Great 1000 Miles Rally (94/07/18)"

MAME History:
- To change 'Difficulty' or 'Language' set 'Service Mode' dipswitch to ON and press reset (F3). Then press P1 Start (1) and select 'System Settings' to enter 'System Setting Menu'. Execute 'Memory the settings and Exit' when quit the menu.

Service Mode reflects the local configuration after playback ends, not the recording. Service Mode is accessed by enabling the DIP Switch which can be toggled with the Service Mode Button (F2) followed by a reset thus cannot be recorded in an INP.

- 0.137u1: Changed VSync to 54Hz.
- 0.141u2: Alex Jackson added MCFG_SCREEN_RAW_PARAMS to Twincobr driver, correcting their refresh rates. Changed VSync to 54.877858 Hz.
- 0.144: Added 'Test Switch' dipswitch.

Note: I don't understand what the rule "Bonus occurrence: 1st and then every 2nd" is referring to - Barthax.

Service Mode:
Service Mode features of this machine reflect the local configuration after playback ends, not the recording. Three different service modes features exist. When the "Dip Switch Display" feature is enabled it will work immediately if there are no credits inserted and/or, if enabled, will appear on exiting the service mode. Two different DIP switches will enable the test pattern of service mode. The Test Switch DIP switch will enter service mode immediately without a machine reset. The Service Mode DIP switch can be toggled with the Service Mode Button (F2) and must be followed by a reset thus cannot be recorded in an INP.

Default Settings:
MAME 0.106:

| MAME 0.250:

From MAME 0.250 after enabling the DIP Switch Display switch.

Lives DIP will only be read in at the time of coin drop, and can be changed up to that point
Bonus Life & Difficulty DIPs will only be read in at the time of 1P start, and can be changed up to that point. Best practice is to ensure settings are correct before recording.

DIP changes at 0.136u4: in 0.136 two "Cross Hatch Pattern" DIP switches existed. The first was adjusted to "Service Mode" and the second one was dropped (but later reintroduced as "Test Switch" in 0.144). The "Unknown" DIP switches were changed to "Unused". The Bonus Life was corrected and the Difficulty was corrected.

Bonus Life changes:
- Up to 0.136: 50K, and then 150K+ / 70K, then every 200K / 50000 / 100000
- From 0.137+: 50k 200k 150k+ / 70k 270k 200k+ / 50k Only / 100k Only
Note: the "DIP Switch Display" screen will show meanings more akin to the older MAMEs:
- DIP EXTEND : 50000,150000 / 70000,200000 / 50000 ONLY / 100000 ONLY

Difficulty changes:

Much better sound / music in the following games Bio-ship Paladin, Vandyke, Black Heart, Acrobat Mission, Koutetsu Yousai Strahl, Thunder Dragon, Hacha Mecha Fighter, Super Spacefortress Macross and GunNail [trap15, David Haywood]. [...]Note: Thunder Dragon parent was not protected, I've marked it as such and removed the protection sim from it. The protected Hacha Mecha Fighter set never worked properly, I've demoted it to non-working as a result, the new bootleg works with full sound and correct game logic. The protected sets don't handshake with the NMK004 so now lack sound (the sim code didn't care). Currently needs an ugly kludge to prevent bioship resetting periodically, the NMK004 is used as a watchdog, but it ends up hitting it slihtly too late so often resets after a few minutes, probably wants even more precise timing for timers / cores / framerate / whatever? Still need to tweak a few things, convert to raw video params, add 2nd buffer. Double buffer NMK16 sprites [David Haywood]. Changed VSync to 56.18 Hz in most games.
