No.16763 Tafoid Administrator Aug 16, 2019, 18:47	I'll allow this despite the flag so we don't have to have it reported again and again. Most driving games with simliar looking roadways have the same issue, "Mach Rider" is another I know off the top of my head.
No.19574 kmg Senior Tester Dec 18, 2021, 04:33	Can this be linked with 00884 please? Even if there eventually end up being differences for some reason whoever fixes the PPU bugs should make sure both versions of this problem are addressed. Also, I don't think there is a Playchoice-10 version of this bug report, but it's worth noting that the Rad Racer games on that driver likewise have this common issue found in many NES racing game titles.
