Sega/Gremlin Borderline audio dream comes true
09/06/17 12:33 AM


Mainly for the users that have been here on MW forums since early post-2000 AD years (2001 to 2003) when Loonybin forum was untamed back then. :-)

One of the posters was trying to recall a tank based game he had briefly noticed as kid back in Greece during his child years. All the time he was certain it was a game that player drives a tank.....far from it. It was Sega's Borderline which players navigate a jeep. Pete was disappointed that audio wasn't supported (all analog discrete audio sounds).

The eventual goal would be discrete emulation instead of relying on external audio samples, but external audio samples will do because the emulation of audio sounds for vicdual hardware games requires more components emulation first before even working on audio of any of the games. As Derrick Renaud described in the past, the Sega analog audio work is a large effort just to get one audio sound effect correct compared to some Atari games that reuse same components for similar audio effects such as "crash" sounds etc.


In case kazzy visits later, he'll be happy to know that the game will incorporate external audio samples thanks work from both Kold and Kale (Angelo).

vicdual.cpp: Added sound samples to Borderline [Angelo Salese, Corrado Tomaselli]

btw: This is from an old post years earlier.


Pete is on far left holding a Borderline manual since it is his favorite vicdual hardware game (Dec. 2006 soCali MAME meet went to Round Table pizza and also to Camelot miniature golf course for arcade games), David/Zephyr, Mr. Do, and me with Frogs manual since Frogs is my favorite vicdual hardware game.







This is Pete's page. https://www.youtube.com/user/kastellorizo

Pete or kazzy or kastellorizo (used different user names on the MW forum) used to visit here regularly from years 2001 to 2003. And returned a few years later and visited off and on.


This is an oldie, but goodie, sort of amusing video clip of where I was describing the parts for a gambling game called King Pin which drewcifer had picked up from an ebay listing back in fall 2006 to Mr. Do while (Pete, Mr. Do, David/Zephyr and I) were dining at Round Table pizza parlor in Fullerton, CA. This was in December 2006 when Pete was attending the IEEE conference that was held in San Diego, CA that year. Pete traveled via Amtrak to Fullerton where I met Pete. Mr Do. and David were also there at the train station as well to meet Pete. It was a good MAME meet and also getting to meet Pete in person for the first time.

The entertaining part about the video clip was when I was flustered when describing something to Mr. Do and had to start all over of what I was explaining of the parts that drewcifer had purchased from a seller at the time in fall 2006. David was laughing and Pete was busy sneaking with getting a video of me while I was talking at the moment. It is amusing seeing video clip once again many years later.

Somewhat visible in the video clip is a box of manuals and schematics that I had brought to the MAME meet. The box probably had 100 various items of manuals and schematics. The item I was holding in my hand was an animal call that I had forgot to take out of the box before placing paperwork inside the box when heading to the MAME meet.

If reading the comments on Youtube of the video clip made years earlier, jop's reference was regarding my favorite arcade video game of Gremlin's Frogs. Frogs uses discrete hardware components to generate audio sound effects. The Frogs manual includes the schematics pages that show how audio is generated. The schematics are referred when trying to emulate audio sounds and Frogs is one of the games where only a portion of the sound effects are emulated.
