Using the new seed SKHCGPTMBB and strategy (thanks Mechalink and Seerskye for the work here!), I've improved and updated my previous world record by over 8 minutes! It has a few minor mistakes (mainly related to got the faster frame rate and load times that throw off my timing) and 2 not-great mage fights, but overall it's not bad The work continues!

This was played on the latest version of Beetle Saturn core of RetroArch 1.17 as of 2.6.24.
