DICE update - Stunt Cycle getting DICE support

Stunt Cycle. Made an attempt at the first emulation of a ROM-using discrete logic game:

Performance averages about 45 FPS on a 3.4 GHz CPU, which isn't too bad considering the complexity of the game, and the use of high frequency (by 1970s standards) clocks on some logic. Unfortunately the speed of the simulation is highly dependent on the speed of the motorcycle, so it ranges from about 55 FPS when moving at minimum throttle, to 35 FPS at maximum. Makes timing the jumps a bit trickier.

Sound is not supported yet, and there are still a few minor bugs to work out. Stay tuned!

I am guessing the Stunt Cycle pcb from 2007 eventually led to Adam's DICE work in 2012.

A huge box arrived today

Stunt Cycle (Atari, 1975, original PCB)
A couple of discrete 'Tank' boards (Atari/Kee Games, 1974)

- Stunt Cycle... OK, dumped both PROMs with no issues.

very nice. Something I didn't think we would see.

I never knew they were little buses that you jump over until seeing the Dice shot. I thought they were logs. That's one big bike. If it wasn't jumping it could just monster truck over them.

>very nice. Something I didn't think we would see.

For Atari non-cpu, rom usage games, my guess was either Stunt Cycle or maybe Anti-Aircraft would be first ones to appear. Stunt Cycle won out.

btw: The crowd cheer sound effect of Stunt Cycle sounds similar to the wall game of Gremlin's Trap Shoot. Since Trap Shoot was a popular wall game that was at many places
a year before Atari Stunt Cycle was marketed, I'd say Atari Stunt Cycle programmers liked Trap Shoot's audience cheer effect and copied the cheer sound effect circuits of Trap Shoot and added that into Stunt Cycle.

Heh. They will seem big once the number reaches 15 in length of needing to jump over.


>That's one big bike. If it wasn't jumping it could just monster truck over them.

With this being a tribute to Evil Knievel back then, nobody thought of
monster trucking over the buses then. ;-)

This is *excellent* news and it's great to see Stunt Cycle finally being emulated.

It's awesome to see TTL emulation evolving. I was beginning to wonder if we were even going to see these games properly emulated.

I made a video last year of a completely restored cabinet.
If dice can support sound samples in the interim, I will get us some clean samples to work with.
The art department has the interior shroud and bezel.
We would have to create the screen overlay.

Great title to support!
It covers so much of early childhood gaming.

You did okay there.

Definitely not the same without the scenery piece with inserted instruction card.

The only external audio sample that might be do-able is "crowd-cheer" sound effect.
The other sound effects fluctuate way too much in which trying to run them as external audio sample(s) wouldn't be feasible imo.

Good thing Stunt Cycle manual/pdf files are around and show how the various audio sound effects are generated.

Couriersud's last MAME update, from a few weeks ago, included analog circuitry input/output support. If Stunt Cycle eventually gets MAME support, then hopefully audio support might be possible later even though it might be awhile before that happens.


>We would have to create the screen overlay.

If anything to get, it should be very very tight closeups with camera on each of the on screen decal/stickers on Stunt Cycle cab. That is definitely needed in order to make sure the overlay pieces are done properly.

The Stunt Cycle manual lists the items on monitor screen as decals that would be adhered to the monitor. "boob tubes", the "sign" piece, and Game over or Player One stickers.

All of those either need to be scanned if any spare pieces available, or next best option is tight camera closeup on each decal piece.

Too bad we couldn't incorporate the artwork with Adam's work. Very nice to see.

That is awesome!

I would play that game whenever it was working at the, Fairmont Hot Springs Resort. Sadly they had the older games in an enclosed walkway along side the big indoor pool and the Humidity was always like 80%.

They had all the Pins as well as a few obscure skee-ball type games that had puppet like targets that had the same hair as those little hideous 60's-70's Troll figures, all stuffed in there. Stunt Cycle was at the very end near the opening so it sometimes worked.

BTW, that little Resort is about 20 miles from Evel Knievel's hometown of Butte, and in the late 70's early 80's that was the ONLY Stunt Cycle I've ever seen!

http://en.wikipedia.org/wiki/Evel_Knievel

Bring on Death Race and my discrete emulation porn collection is complete!

Only ever saw it at out of town arcades and the arcade tents the carnivals used to have back in the day.



There is no law in the arena
