A woman who can not enter the '-1 face' of the vision of Mario 's vision how many times it is reproduced in the work force

"Nintendo released in 1985"Super mario bros"Consists of all 8 stages from the world 1 to the 8, but in fact in allAs many as 256 stagesIt is possible to make it appear. These stages are called "256 w", "256 world", "under cover", etc., one of 256 w is "Minus 1 sideThere is a stage called "YouTube" which is famous for many videos uploaded. A woman who could not enter the "minus 1 side" by all means rewrites the ROM using the emulator and reproduces "minus 1 side" in the power industry.

The way to go to "minus 1 side" can be confirmed from the following movie.

Super Mario Bros. Minus 1 - YouTube


There is a drill pipe going to 1-3 just before the goal of World 1-2.


Move Mario to the edge of the clay pipe ... ...


Jump back over the overhead block.


Succeeding, Mario is sucked into the wall and it passes through.


When you arrive at the place of the warp zone, you enter the soil pipe in front.


Then the stage name that I have never seen "WORLD -1" on the screen was displayed.


"WORLD -1" is exactly the same as stage 7-2. If you swim to the end and enter the clay pipe, you will be returned to the beginning of "WORLD -1", and then loop forever.


Emily St of an American woman made it possible to play minus 1 plane with the emulator. Emily, who loves Super Mario Brothers since childhood, still uses the emulator to play Mario.


Emily, who had heard the existence of a minus one face a few years ago, has repeatedly tried again and again, but abandoned on the way of challenging, it does not go well any times. Emily who wanted to play minus 1 side by all means the next trial was a bold way to remodel Super Mario World's ROM directly by modifying it.

The minus one plane is expressed as "-1 plane" if it is correctly written, it is hard to understand if it is made into a character, but "space" is inserted before -1 to become "(space) -1" I will. The Super Mario Brothers uses Nintendo's unique code consisting of numbers and alphabets, the first ten of the codes are numbers 0 to 9, and the alphabets 11 to 35 are used. Each number and alphabet are assigned a pattern etc. used for graphics. And it can be interpreted that "space" is used for 36th code and "(space) -1" is actually "36 - 1".

Emily, who understood the Super Mario Brothers' code, really cares "Why do you move to" 36-1 "when entering the clay" and using a program called "hex editor" to Super Mario Bros. ROM I will confirm. Emily 's numbers and alphabets are listed in the list, "04 03 02" was figured out. This represents a stage that moves from the 1-2 warp zone.


Emiliy, who found "04 03 02" from ROM, noticed something. That means "24 05 24" after "04 03 02". "24" corresponds to "36" in hexadecimal code, so "24 05 24" is "36 05 36", indicating the next warp zone. According to Emily, this sequence of numbers is the cause of moving to "36 - 1 face", that is, "-1 face" when activating a bug. Emily, who clarified the mechanism to move to the -1 plane, tried to edit "04 03 02" to "08 03 02" and check with the game, the numbers on the clay pipe had changed spectacularly.


Actually going into the clay pipe of "8" and moved to "8-1" brilliantly. However, Emily has not satisfied with this alone and entered the number of the stage which can not actually play "09 03 02". As a result, I succeeded in playing "9-1" which I can not play normally. Emily played various stages that you can not normally play in this way, but it seems that Emily had some problems, such as freezing and bugs all of it.


"-1 face" has been talked about for quite a while and in Japan it is alreadySite to clarify the mechanismIt is open to the public. However, Emily 's Super Mario Brothers' love of being unfamiliar exists because he wanted to play "- 1 side", he checked himself up to the ROM and touched it.
