Super Mario Bros.: Sigma Mario I+II

'Sigma Mario' is Eden GT's first hack, made in 2014. What's difficult about this hack is that the enemies are changed to hyper-fast! Glitches are also required. There is also a sequel in the zip file named Sigma Mario II, which requires less glitches.
Further guidelines about the hacks' information are enclosed within the info.txt file.

└―――――――――――――――――――┘ Made by Eden GT
Patch to a 40,976 byte Japan/US Super Mario Bros. ROM.

Features, recommendations:
-Nearly all enemies have extremely fast speeds. Save states neccessary.
-Bugs, glitches may be used freely. However, in Sigma Mario II, the following techniques are forbidden from regular play: Walljumping, corner clipping, Devil's spell, direct wall clipping. Anything else is fine.
-Both have 32 levels.

"Sigma Mario" was my first published long hack within mid-2014, and has rather under-mediocore level design for my current tastes. As there are walkthroughs already available for the first one, "Sigma Mario II" is recommended more and does not require tougher glitches to beat the hacks.

"Sigma Mario II" was then produced since somewhere in later 2015, finished early the following year. Has a more approachable beginning and less staleness compared to the first one.
-The ending will display a six digit code that is intended for the upcoming third sequel. Might want to keep backup save states somewhere in case of a gameplay "mistake".

Both are beatable as they were playtested before release.
