HL Coins Land is a Super Mario Bros. ROM hack created by HappyLee somewhere in the mid-2000s where your goal is to collect 100 coins by World X-3 to get extra lives and proceed in the game. Like Air 2 and Hard Relay Mario, savestates and abuse of complex Super Mario Bros. glitches are required to collect every coin and beat every level, making this hack practically impossible to complete in real-time.
My TAS beats HappyLee's 2011 run by 14.19 seconds thanks to better optimization on most stages.
Actual rerecord count is 18910.
