Mega Man X5/X6 Potential Quick Kills

In Mega Man X6 when you go into a refight teleporter there's a very small frame window where you're allowed to fire a weapon after being teleported into the boss room. However the weapon immediately despawns since the screen is still black and hasn't faded back in yet. If you could find a way to stop the weapon from despawning or do something else with this quirk I feel like quick kills would be possible.

If you could stop the weapon despawn entirely i feel like F-Laser in X5 would be your best option and Yammar Option (if you can fire after you just get the 1 frame to form a shield) or Metal Anchor.

This window is very easy to hit in real time utilizing the in-game rapid fire menu option. Ground Dash specifically has an interesting quirk where you softlock the game since the poop rock immediately despawns and X is locked into place since he can't kick the poop. Here's a video of that https://www.youtube.com/watch?v=K5yWChjnIAs

This would save a ridiculous amount of time in X5, especially for the All Stages Unarmored X category. This would also save a ton of time for X in X6.

So yeah, if you like either of these games and potentially want to improve the speedruns get cracking on solving quick kills.
