Scorpion overload
08/02/23 03:59 PM




> Well, when I try to play the game Scorpion (ROM set 0.106), I got these messages on screen (see pic).
I presume this game requires dedicated samples files.
I checked on https://samples.mameworld.info/ website but this
particular game is not mentioned. I tried also to google it but no luck.
Due to the fact the game is quite old, I'm surprised they are not available yet... or do I misinterpreted the sample message I got?



Way too long ago since .106 was in 2006 when Aaron Giles introduced the video rewrite output which first added support for bezels back then. Maybe an update for external audio samples page (Twisty’s samples site) should get updated with disclaimer that the site was for very old versions of MAME before various speech hardware was emulated or analog components were emulated.

From MASH Mameinfo over the years regarding Scorpion since there had been many improvements
over the many years. The various components for audio output likely not yet emulated back in 2006.



WIP
* 0.242: Added 'Lives' dipswitch to clone Aracnis (bootleg of Scorpion on Moon Cresta hardware) [chaneman]. Fixed default coinage to 1C_1C [Angelo Salese].
* 0.202: Moved Scorpion's extra ROM and sound handlers into address maps [AJR].
* 0.167: Fixed Digitalker speed. The interrupt command was triggered at the end of the post-sample blank instead of at the start. It's a tight guess but is on par with real hardware footage of Scorpion [kazblox].
* 0.155: Osso fixed Scorpion save state regression.
* 0.148u2: Correct rom labels for Scorpion. Redumped clone Scorpion (set 2) - Game now playable [Tirino73]. Added new maincpu rom ($3000) to clone (set 2). Added digitalker rom ($0) from (set 2) to Scorpion (set 1).
* 0.148u1: Modernized Digitalker sound device [Andrew Gardner].
* 0.136u4: f205v added clone Aracnis (bootleg of Scorpion on Moon Cresta hardware).
* 15th February 2010: f205v dumped Aracnis (bootleg 1982) of Scorpion.
* 0.133u5: Couriersud fixed missing sound in Scorpion and clones.
* 0.133u1: Renamed (scorpnmc) to (scorpionmc), (scrpiona) to (scorpiona) and (scrpionb) to (scorpionb).
* 0.131u4: Olivier Galibert fixed Digitalker mode 2.
* 0.129u1: Olivier Galibert added Digitalker (4MHz) speech emulation to Scorpion.
* 0.124u1: Added Discrete sound. Changed visible area to 224x768 and palettesize to 32 colors.
* 0.122u5: Couriersud fixed Cocktail dipswitch settings in Scorpion.
* 0.118u6: David Haywood added clone Scorpion (set 3).
* 27th August 2007: f205v and Corrado Tomaselli dumped Scorpion (set 3). Speech chip is a digitalker MM54104, 100% certain of it. The wavefile shows the distinctive half-period zeroing. The voice roms are already dumped, they're at 32_a3.6e, 32_a2.6d and 32_a1.6c, concatenated in that order. There are 45 words, most if not all of which are from the standard national semiconductor SSR1/SSR2 set.
* 0.104u5: Aaron Giles fixed Scorpion doesn't pass the ram/rom initializing.
* 5th December 2005: f205v dumped Scorpion (on galaxy). EPROM sc04 is BROKEN. Protective glass is smashed and the chip is not working at all. Blister only, no PCB.
* 0.89u4: chaneman added 'Difficulty' dipswitch. Swapped sound1 roms ($0, 2000). Changed parent and clone descriptions to 'Scorpion'.
* 0.89u2: Pierpaolo Prazzoli added 'Scoprion (set 1)' (Zaccaria 1982) and clone (set 2).
* 0.63: Changed description to 'Scorpion (Moon Cresta hardware)'. Renamed (scorpng) to (scorpnmc).
* 0.59: Mike Coates added 'Scorpion (bootleg on Galaxian hardware)' (Dorneer 19??).
* 9th February 2002: Stephane Humbert fixed the dipswitches, inputs and a few other problems in the Galaxian driver, and re-added the Scorpion bootleg running on the Galaxian hardware.
* 18th October 2001: Mike Coates added a bootleg version of Scorpion running on Galaxian hardware, but the addition isn't complete yet.


For looking over current source code status, here are links to Zaccaria Scorpion.
I am unsure about sound imperfect status since no specific notes stand out within the source files regarding Scorpion audio output.

// Scorpion hardware; based on Scramble but with a 3rd AY-8910 and a speech chip

https://github.com/mamedev/mame/blob/49e...xian.cpp#L16443


GAME( 1982, scorpion, 0, scorpion, scorpion, zac_scorpion_state, init_scorpion, ROT90, "Zaccaria", "Scorpion (set 1)", MACHINE_IMPERFECT_SOUND | MACHINE_SUPPORTS_SAVE)




I guess see what happens with a newer version of MAME.
