After lots of whining, and going as far as creating a whole thread on the subject, I suddenly realize this sticky thread and, oh, my god, did I facepalm hard! Like I said before, I'm not the most computer/tech savvy guy out there, and I'm not particularly good with complicated fixes to video game and computer program glitches and issues, so this launcher really made things easier for me.
There are still a few graphical hiccups when I run the games, but at least the wobbly wheels glitch is taken care of, which makes the game playable. I can live with my wheels turning black or becoming a fire sprite/tile whenever I fire the weapon, because now the games are fluid and the races finally feel like races and not waiting games. Plus, those graphic glitches are minor and happen rarely, I don't think I'll waste any time whatsoever trying to fix them, as they are far from being game-breaking.
As always, thanks to the amazeballs GOG community for helping each other solving whichever problems we have with our games. It's stuff like this that makes me proud to be a part of this fine community. Also, a big thank you to GOG themselves, for making these superb games available and making them run on our modern machines and OSes, even though at times an "Interstate '76" comes along, I still know they did everything in their power to make it compatible with what they were given. For the record, Interstate '76 is the only GOG game, out of the 79 I own, that I had any problem with.
[EDIT] I'm so sorry for the people out there who haven't been able to get this game running properly, even with the launcher... I don't know if it helps, but I'm running a pretty old laptop with Windows Vista 32-bit Home Edition, a 1.9 GHz AMD Turion processor that came with an "up to 896 MB" ATI Radeon Xpress 1250 HyperMemory and 2 GB DDR2. I downloaded the 2.0 version of the launcher with all the Glide stuff and I disable AVG whenever playing the games.
