This particular run of Metroid uses the password "NARPAS SWORD0 000000 000000" to complete the game as fast as possible. The password starts the player off with every upgrade in the game (minus the wave beam) and gives the player unlimited health and missiles, therefore rendering the need to collect any of these things completely unnecessary and allowing the player to quickly glitch to Tourian. This particular run is not very well optimized, there is a lot of room for further optimization and lag reduction but overall the run still beats the current RTA record as of writing (4:44 vs 4:33) and I am satisfied with it.

This is a TAS where Metroid for the NES crashes with the password "GUILTY UNLESS PROVED MEDUSA", and it's a pretty short movie for FCEUX if I do say so myself!

Warning: awesome sfx manipulation, ignore this movie if you want to be surprised once it's complete.

jump sounds, bullet sounds (muted whne exploding trick), movement, music filling (mostly melody but drums too with beams and jumps).

159 frames faster than LordTom, need 3 frames to save 10 frames, and probably can shave more frames if I get extraordinary luck.

I would appreaciate it if you would PM or comment me about the sounds!

Further improved OoB scenes and better pause handling and improved Kraid fight. 127 frames faster than LordTom currently.

"Completely" redone WIP. Better positioning horizontally/vertically, better jumps and OoB improvements. "Resets" the game 93 frames faster by than LordTom.

Other notes:

• Currently investigating how to improve Kraid boss.
• I've removed 3 lag frames by pausing for 1 frame (T, empty, T) so it saves 1 frame overall. However, I believe I get an extended 6 frames delay once the boss died because of that.
• Lag frames and boss 1st missile shoot time depends on Samus previous state and position and also pauses.

This movie shows all my discoveries so far:

• You can change direction on "first" frames without losing any speed (after starting the game, after entering a room, after picking up item etc)
• I decrease my speed earlier before picking up the item so I have a "lower" speed reduction.
• I do it twice after picking up the item to get a better jump after unmorphing to spawn platform and to shoot the door 1 frame faster
• Notice that I exit the door with L. While this doesn't save time here, it changes Samus' postion once he travels to next room. Obviously if you would go to right, it's faster to move right (as I did at the elevator)
• Different OoB ending (edit: also avoided a morph jump)
• Juggling lag frame positions without changing lag count by shooting and manuevering differently after OoB

19 frames faster so far. Notice that I've actually had to make 1-2 frame delay otherwise the TAS magically desyncs without any ROM change (the trace log is different however)
