I'm stuck in brinstar but it's not the newb bridge (super metroid)

I have the morph ball, bombs, and reg missiles. The only ways out of the place I'm in are a room I fell out of and a door blocked by a super missile gate, and no its not the gate that you can't normally hit because it's facing away.

This doesn't look like the OG Super Metroid  based on the map you gave. What hack is this?

[TinyHatLogan]

Super Metroid (japan, USA) (En,Ja) [Hack by Banana Oyaji v1.06] (~Metroid Legacy) (Snes9x 2010)

You need to head back the way you came, and go and defeat Spore Spawn. You'll need to do a wall-jump near the pipe to get back up.

Actually, I figured it out and if you head right there's a fake wall at the top that leads to the high jump
