Famiclone 1.0

A series of patches for Spelunker that lets you fall further.

-Leg Day (Never die if you fall)
-Fall 2X

If you never die if you fall, you can get trapped easily. However, that is still much less frustrating. 
I recommend the Fall 2X patch, as it is closer to the original Atari XL/XE fall height.

Alternatively these Game Genie codes can be used: ZPIAEX is 2X, NYIAEX maxes it out to 255 (not included), and AIIAOZ is don't die at any height.

Thanks Cpt Rufus for the suggestion.
