Emulator used
BizHawk version 2.7
ROM version
Rockman Mega World (J) (a1)
The reason for the alternate ROM set is that this is the only version that has working SRAM in BizHawk due to certain cartridge hardware aspects not emulated as of this writing.
This is part of an all games zipless run that I am doing. I managed to finish up Mega Man 1 in 20:13.128 from power on. I do plan on letting the credits play for each game so for a more accurate time I should measure from selection menu to last hit on the final boss.
