A Level Select Cheat Code's Not Working For Me

[Neon Streak]

I'm working on ripping graphics from the SNES version of The First Samurai.

Since most of the sprites and stage tiles are stored compressed in VRAM, I found a level select code to get me to the stages I wanna rip from faster. Unfortunately, every time I enter the code and the game begins...it starts me at the very first level of the game!

I don't get it. I entered the code correctly, so why didn't it work? Can someone who's entered this level select code before help me out here?

P.S: Here's how the code works: On the title screen you press SELECT to go to the options menu, then you hold down L, R, X, and A and press one of the directional buttons to be warped directly to a level (The level you go to depends on which directional button you pressed.).

It's because keyboards can't handle more than 3 keys being pressed at the same time. Go to the key config and set l,r,x,a to one key (let's say, j), then you just have to hold down j and press a direction key.
