MAMEWorld Forums - News - Re: [DUMP] Offer to dump & emulate SEGA Space Ship

>As far as I know, I'm the only known owner of a SEGA Space Ship cabinet.

That is a find there imo.

That old entry from well over 10 years earlier might be a mistake. Back in 2000, there weren't as many web sites to refer to regarding any questions of games made back in 1970s. TAFA (arcadeflyers.com) was just getting started at the time as well.

Good researching there on your part.

=========
Game & PCB are (with no doubt possible) original SEGA's.
The PCB was failing and I fixed it twice (it failed again 1 week after the first fix).

Game is a 99% clone of Cinematronic's Space Wars (Mame dir "spacewar").
There is difference in code handling the time per credit.
For the same dip-switch settings, SEGA awards you more play time.
Cinematronics : settings are 45s / 1 min / 1 min 30 / 2 min per credit
Sega : settings are 1 min / 1 min 30 / 2 min / 2 min 30 per credit.

Difference is in game's code, not in electronics.
There are also some differences in some PROM that handle internal CCPU tasks, but theses differences are in unused bits (why ?).

I offer to the Mame community to finish my dumping task (I dumped only 20% of the PROMs, needed for my repair) and to add this "new" game to Mame.

My questions is : is the Mame community interrested in this offer ?
=======

As Stiletto mentions, it is yes. Having all of the roms/proms backed up should help assist other pcb owners in case someone else happens to have a pcb and needs to repair/replace a prom chip in the future. A few folks here can testify about being able to repair their pcbs in case a rom has gone sour on the pcb such as some of the early 1980s games hardware.

Sega Space Ship should eventually be in the Cinematronics driver as likely a clone of Cinematronics. I am guessing Sega licensed from Cinematronics back then.

If you can provide the label names of roms/proms on pcb, dump data from the roms and proms from pcb, list part numbers from the pcb, all that information could eventually be added to the Cinemat.c driver file.

see Stiletto, if needing to sometime later on.

stephh is another person to talk to. Adding dip switch info to some of the drivers is his area.

As for artwork, if able to add that later, such as that bezel piece, vectorzorg is the person you want to talk to if needing to get any scanning tips.

Thanks if able to have anything of Sega Space Ship documented in MAME later.

btw: The minor issue with the games in Cinematronics driver file, is they still use external audio files that are still needed for playing some of the audio effects.

Since many of the games did not have roms storing audio, adding code to support discrete audio hardware is still needed for the games in Cinematronics driver. So far, most of the games with discrete audio emulation are Midway 8080 hardware, various Atari 1970s era games, and some of the Nintendo games (Donkey Kong, Mario etc), a couple of the Gremlin vicdual.c hardware games.

If you have a manual and logic schematics for Sega Space Ship, getting those scanned later might be needed because there could be the possibility that audio sounds generated from Sega Space Ship might be played slightly different compared to Cinematronic Space Wars.

The games might look the same, but game play might be different and audio might be different as well.
