there are often bunch of accidental new ceres WR as peeps put the time as RTA instead of IGT as they can't read the rule saying IGT only

too late i did see this FUNgineer, and i'm no longer BEJ hero BibleThump

first of all, the wall is composed of bombs block in the non escape state which lead to a grey door, secondly you need to use ST beam to be able to enter the door but you need to always use ST beam to enter all the door in reserve as all of them are grey since its suposed to be a 1 way door, i knew that andrew as done it i just don't have the video to show it, but it was done and i don't remember well but i think it trigger the escape flag when you return to the room with the gate, i might be wrong on that though

the wiki say: Timing for all full categories begins on the frame that the Missile pointer disappears upon confirming "Start Game." Timing for all full categories ends on the first frame that Samus is facing forward on her Gunship before it departs the exploding Zebes. https://wiki.supermetroid.run/Timing

if you are asking if ther is a sub cat for emu, VC and OG console then the answer is no, all time is counted in the same place, you can even see if somebody use an emu by the little emu on platform, you can see if someone use an snes classic, or a wiiu or the like

you can run the game with a virtual console or an emulator if you want, the OG console is faster than the VC and VC iirc is faster than the emu, if with emu you can't use Zsnes and can't use snes9x v1.43 and lower, also zero mission is the remake of nestroid (metroid 1) not super metroid.

you don't have to be with an OG console if its just for the sake of running the game, but having the OG console will have a good advantage since the frame rate is superior and you won't have any input delay, will just need a good CRT screen and everything will be perfect. sadly i don't know where to find one though but somebody will be able to point the direction for you fo sure
