Collision detection is still not working in this game. The scores that I checked from earlier MAME versions tilt in the first race, halting the recording. Showstopper bugs have been reported both for this game and for its source at mametesters.com.
ozz has maxed out the score on this game, i would imagine by taking advantage of the collision problems (can't get his .inp to playback)
all in all, this game should probably be blocked from competition for the time being.

one immediately noticeable thing is that computer controlled cars (and your own?) can go off the left side of the road and come back on with no problems, giving a wider berth for th race)
from mametesters.com:
Source issues:
grchamp: Known Issues: PC3259 handling (for collision detection) is not accurate. Collision detection does work, but there are bits which define the type of collision (and determine whether a pit stop is required) that I don't know how to handle.
grchamp: Known Issues: sound: missing speech and engine noise
grchamp: Known Issues: rain rendering is probably wrong
grchamp: Known Issues: "radar" is probably wrong
grchamp: Known Issues: LED and tachometer display are missing/faked Note that a dipswitch setting allows score to be displayed
onscreen, but there's no equivalent for tachometer.
reported bugs:
grchamp.c grchamp: If you drive in tunnels, all graphics get lost except for yourself (the car you're controlling).
grchamp137b12gre Jonemaan
grchamp.c grchamp: Some of the game sprites (such as the flagman and the lightning) and the letters are corrupted at the beginning of even numbered courses. During this, the enemy cars are invisible once you start moving.

grchamp.c grchamp: Grand Champion controls stops to work just after started second course.

I only played through the 1st level but the game seems playable to me. Certainly not perfect, but not bad enough to be thrown out. If the game does in fact crash after the second round then by all means archive it.
I also tried ozz's inp and it tilts after the 1st round. I tried midas, direct, and no sound. I also tried draw every frame. I am in windows XP however. Maybe someone with 98 or 98se can try it out.
