Hey all.
So I've recently made this game available on Speedrun.com. Timing rules are available. Hope y'all run it!
If anybody has any questions or whatnot, please let me know. I'd adore if this game got more love. This has been one of my fav games since childhood!
Just to give a heads up if anybody is interested:
Game came in two versions, one with wheel and pedals, one with stick and buttons, so playing with a stick, gamepad, or keyboard is totally fine (though, in the arcade with the 360 wheel it's a trip, spinning that bastard like crazy!)
As of typing this (June 16th 2018) my Sum of Best is in the 10:09 range... Feel like for me 10:11.x would be about as low as I could conceivably grind it. Just wanted to give a quick rundown of stuff that might be useful.
Emulator versions: if you want to submit to TwinGalaxies, or at least use the standardized MAME version, look up WolfMAME: it's a version of MAME that doesn't allow save states, pauses, etc. to try to help alleviate cheating. Over here as mod I'm cool with any MAME version atm, but WolfMAME is a good way to go about it, and you'd be able to submit to TG if you so desire. I'm currently using Wolfmame .0196 and had great luck.
Note that as you complete levels without continuing, the in-game timer speeds up to make life harder for you, and IL runs use IGT exclusively, so you're going to want to do IL runs from startup.
Timing starts on level-selection from what I've been able to tell cars sound different and 'feel' different, but the general speed is the same as far as I can tell, or at least very close. I wish I could get more concrete info on the cars but at this point, it seems to come down to what you prefer.
Starting at level 05 is not necessary, I've just found it the easiest overall route. Levels get harder as you complete levels without continuing so I've found this the best route: timing rules make it any order you wish.
TECH: General rule is you want to
a)cut corners as much as possible (shortest distance is always a straight line)
and
b)turn the car as little as possible (shortest distance, straight line, etc.)
This includes really limiting how much your car skids/fishtails. Generally speaking, the noisier the turn, the slower it is, but you can only limit squealing, not eliminate it.
One very important tactic is what I call tap-turning: by quickly tapping, releasing, and tapping the steering direction again, you can adjust direction through turns while keeping the rear-end from skidding out as much as possible. You'll get better as you practice it, but this should be your default through many corners.
To help shave time, watch the IL videos to find shortcuts and skips: I doubt they're perfectly optimized but you can find the major skips/strats I've managed to find. Be careful though: ILs won't have the added troll-cars that will happen later in the full run.
