Question about discrete for MAME
#258282 - 06/25/11 05:49 AM


will MAME have a discrete games side project similar to mess?



I’m convinced Mario is a hobo.
He wakes up everyday in the same clothes, runs around in sewers, and collects coins for a living.
At the end of the day, he uses the coins to buy mushrooms

I would imagine that discrete games would be (eventually) included in the baseline MAME, just like the discrete sound chips have been done. I gather any game data (the TTL equivalent of ROM images) would end up inside a zip file, rather than being built in like Pong was back in the late 1990s.

Thank you. If MAME does decide on simulating TTL chips,I would like to see Breakout and the original Tank.The only simulated Breakout that I know of came in the form of a PC game that Atari promoted to Taco Bell awhile back.But it was called Super Breakout even thought it was the Original.

For your Tank fix you could always try Combat on an Atari 2600 emulator...

You'll have to settle with Super Breakout for now.

MAME currently does emulate some of the TTL chip hardware used with some games.

As for emulating Tank, two hurdles specifically concerning Tank. The roms are a custom type rom and required someone (MAMEdev member?) visiting a university library (iirc) and getting a book from 1970s era in order to find out what the exact chip was that stores the game rom data so a specific adapter could be made to dump roms from a Tank pcb.

I am pretty sure Tank rom(s) may have already been dumped a few times earlier by some of the repair shops in order to repair Tank cabs or cocktail tables. But that stuff probably isn't online these days compared to Naomi hardware titles.

Besides the hurdle of dumping Tank rom(s), is the fact that Tank uses 2 pcbs while Fun Games' Tankers (a clone of Tank) uses 3 pcbs. The number of pcbs used in a non-cpu game presents a huge, emulation speed challenge.


Last year, Juergen B. (MAMEdev member) partially emulated Pong with his TTL emulation project and on state-of-the-art computers last year....the frame speed was no more than 7 frames per second.....and pong is a single board pcb. It would probably be same speed frame, maybe less, if original Breakout were to be emulated as well.

For speed of emulating a 2-pcb system like Tank....it might probably only run .05 to 1 frames per second on current state-of-the-art computers. A fair number of non-cpu games used multiple pcbs (Computer Space, Tank, Midway Ball Park, some of the racing games etc)

Really? But a Tanker is a pretty different thing to a Tank - I would have assumed it was an 18 wheeler clone or something - how daft!

Heh. Well...it was one that you added to DL web site years earlier. ;-)

Here's my earlier reply regarding the two Tank games that I played back in 1970s.

==
For oddities, Kee Games Tank used a two board pcb setup while Fun Games' Tankers made use of a 3 pcb setup for handling Tankers. Both games should have identical gameplay. I occasionally played both games way back in mid 1970s. From what I recall, Tank was the better of the two imo because it had better, faster response when moving the tank around the screen during gameplay.

It gets better now that Midway's 18 Wheeler is now a supported under mw18w.c as a preliminary driver file.


Here is a videoclip of Midway's 18 Wheeler in action. The audio is all discrete components material. The external artwork support will be a truckload of a chore in order to fully emulate Midway's version of 18 Wheeler.

I think I missed this post.

The documentation was successfully obtained back in March. No one's made an adapter that I am aware of.

Yeah, but the part where he posted the ROM contents in ASCII was kind of awesome

Yeah, but the name change/tantrum after being edited wasn't.

I have a couple of Tank boards. I thought someone has already dumped those ROMs? If not and I can get the adapter info I can dump them (or 'it' I think there's only 1)
