Got this off a no reset run after I finished my exams.
Not the best beginning game, got only 1/3 Secret SCs but had bad grass shortcuts in Tiger Temple, sloppy Papu's Pyramid, lost Sacred Fire in the last lap of Dragon Mines, the game ate my R1 input at the end of Polar Pass's 1st lap and would not let me jump but I cancelled it out with a MegaSC in the last lap, good Tiny Arena with only 1 MegaSC, lost 7 seconds in Komodo Joe's Challenge, bad Hot Air Skyway 1st lap due to getting pushed off by Cortex in the start lap, messy Oxide Station last lap and lost about 14 seconds in Pinstripe's Challenge.
Unfortunately, this run is the equivalent of a 51:01 excluding the Tiny Arena shortcut so it does not beat my 50:31, so I hope to get a 49:xx soon.
