First, the video linked for the run is more for youtube, please Moderator watch the video below - i am showing the emulator (BigPEmu, played on 2nd November 2023), giving comments and showing my setup (how i played) just for you at the end of the video

Second, big thanks to TheGreenThunder and to 16xa2nd - they helped me with the routing or gave me tips

Third, here are ALL I KNOW for the future of runs

q, w. 6 then 1+3 --then-- s,d,9,d,9,d,o,w,6,p,o,o,w 2 w : Start the cheats,

W + 5 :enable cheats

W+ 8 :tracker

W+1234 at the same time :refill ammo (doesnt work on keyboard for me)

W + 6 / 9 :card level

w+ s/d :teleportation

NOW THIS IS GOOD : o+p (on keyboard) brings you automatically to the menu- useful if you want to load a savefile

Press 8 for mini-map

If you press left-right-left-right rapidly, you get rid of the facehugger

go up the Sub-level in the elevator (from lvl4 to lvl5) : you have to hold Backwards while pressing the button to open/close a door..... the Backwards button is arrow down, the Activate a door is D by default on keyboard - to go to floor 2 from 5 you need to hold Arrow up + D

Tunnels

Here's the vents tunnels mapping typed in french

T2

G-D-G-Triple Gauche-D-G

D-G-Triple droite- D-G-D

T3

Gauche-Droite-Droite-gauche-Gauche

droit-droite-gauche-gauche-droit

Here's a tip for Post-Pshhh room: you have to pick health, always have 5 enemies to kill, ,then move to next room for Pulse + Shells and destroy 3 more aliens - For queen, i suggest destroying 4 eggs that are visible from the entrance then straf to the right in the room and go around to pick the card, straf is the only possibility
