I used to be a bit dismissive about this game because of my usual non-interest on playing anything below the 150cc cup, but as RetroAchievements dragged me into the pits of doing 50cc/100cc runs and playing with other characters...I also ended up having to fine tune my driving more than ever before, between the 36 point runs [which could be done in 100cc rather than 150cc, so sometimes I used that cheese to get the character 36p cheevos], the Wall-less achievements [that was definitely something to go through] and most notably some of the Time Trial achievements pushing me to squeeze the juice out of the miniturbo drifts as much as possible - most notably at Sherbet Land and using the shortcut at Yoshi's Valley twice.
So uhhh yeah I think I like Mario Kart 64 more than ever before, even if some of those cheevos took forever either by difficulty [Yoshi Valley TT, Stars, Toadkyo Drafting to get the two drafts and win] or just by the pace [anything related to Wario Stadium and Rainbow Road due to the length, 50cc runs].
There's some cups that are missing since I either considered them fairly easy to do [50cc and maybe 100cc? I forgot] or aren't retry-less runs [they ARE 36 points runs but with one or two retries so they aren't in the list yet]. Uhhh this may get tidied up better later on.
So, uhh, since RetroAchievements had some cheevos for finishing whole cups without hitting walls [and Flower Cup onwards allowing you to retry tracks], I ended up kind of compressing the 40 minutes or so of pain into a 10 minute video - except for Mushroom Cup since it was the easiest one of them all. Below there's also a playlist with the video AND the raw runs - fails included.
