Summary 07880: grchamp: Several regression since mame 0.103
Description Grand Champion had several regressions made after version 0.103, such as worse/missing sound and voice samples, worse graphics (black walls in tunnels and sprite priority bug in the headlights, missing fog effects, corrupted text layers, corrupted graphics at the podium).
Steps To Reproduce just play the game in both mame versions (0.103 and 0.228). the older driver is not perfect since other cars races outside of the track boundaries as well. but despite this, that version of the driver is way superior in almost every aspect.

I think by and large all this is known and why the machine is flagged as having incorrect graphics and sound.
I'd argue that this driver/machine be flagged as NOT_WORKING - likely has never worked to any sufficient capacity.

I agree and I know that this driver was always far from perfect, but the 0.103 driver was much closer to the real thing than the latest one. At least in version 0.103 you can actually play the game, having most part of the funcionalities implemented, such as headlights during tunnel and fog sectors, voice samples at the beginning of each race and when you win a race, better rain and thunder implementation. All these things were better before, that's why I decided to open this report.
