I personally think Megaman X6 Tweaks Patcher still need to include another few options to improve the gameplay.
Can you hear me out?
I think a stage must be able to clear if you are given the choice to proceed to that optional path even if the character is without special weapon and part.
As for collecting parts, rescuing Reploids, and proceeding to optional paths, all characters must be able to do it later with either the correct parts or special weapons.
This tweaks patcher make those impossible to clear stages and rescued Reploids without certain special weapons and parts become possible.
1) Amazon Area (Hidden Area)
Requirement: Enable Air Dash for X and Shadow.
Even with Nightmare Rain effect, X, Falcon, Shadow, and Zero are able to proceed to the next platform without the need of special weapons or parts.
2) Central Museum
Requirement: Enable Air Dash for X and Shadow.
The same goes to Central Museum when the character was teleport to Pyramid area with Nightmare Rain effect. No problem!
3) Northpole Area (Hidden Area)
Requirement: Speedster and Ensuizan air move mode 3 repetition.
The spikes place where the Wolf Reploid with Jumper is now possible to be saved even with Zero. Never knew you'll think so far ahead.
4) Magma Area
Requirement: Either change the Jump Height to 198 or alter Shadow's saber (charged, tip) to damage Nightmare Iron.
The place to Hidden Area was initially impossible for Shadow. Now you have nailed it!
5) High Max (Hidden Area)
Requirement: Altering the damage table for X, Falcon, and Zero.
I personally prefer a beatable High Max (vulnerable) with X's Z-saber and beatable High Max with Zero's saber (air spin).
I only set the damage value to 1. In fact, I prefer Zero's saber (air spin) to just stun High Max but it was impossible at the moment. Oh well...
However, this is the part that I felt improvement still need to be done even though you have created the Stage Modification:
1) Amazon Area (Extend ceiling)
Is it just me? I actually died even more with the extend ceiling as I get instant death from being push back by the moth enemy.
2) Recycle Lab (Long jump to Capsule/ Hidden Area)
I enjoyed the extent tile by 1. It gave X and Armors to pass through the area with precise jump even without the special weapons and parts.
Well, that is if you enable air dash for X and Shadow + Z-saber on air. However, I can never pulled it through with Zero even with extent tile by 2.
For Zero, with the extent tile by 1, it's possible if you either learned Ensuizan or equipped one part like Speedster/ Hyper Dash/ Jumper.
If I'm wrong about this part, perhaps you can show us the way how to pulled it through with just Zero.
If not, I propose that you create an option by changing the location of the 'blue portal to the hidden stage' to the platform before you make the long jump.
I think place it near the left side of the wall with some height that only reachable with wall jump.
3) Secret Lab 1 (spikes area)
Remove more spikes (no requirements):
Yup, now without Ice Burst Weapon or Jumper part also can make it through.
However, I think this is too easy. Instead some challenge should be included. I mention this before.
Why not change the setup a bit more from 'remove some spike'? This time exclude some spikes behind the wolf enemy.
And now, the remaining issues regarding Megaman X6 platform itself.
1) Inami Temple
I do agree with normie players. The path where you can get Dr. Light's capsule is either too narrow or too many spikes.
Of course we all know it can be easily obtained if purposely getting hit by bat enemy while equipped with Shock Buffer and D. Barrier.
But how about a perfect run? Not everyone can pulled off the trick like 'X MaverickHunter' on the youtube.
2) Laser Institute (Hidden Area)
Again, maybe it's just me. The Reploids above the W-Tank is a hassle to be rescued. I need to try and error a lot of time.
Can you create an option to remove the first part of spikes where we need to wall jump pass it?
Or maybe just add 1 tile of platform on it?
3) Central Museum
I hate that I have to visit this stage a lot of time to rescue all the Reploids and getting all the parts.
It's so random. I really hope something can be done on this stage!
My idea is why not make it this way:
1st Totem bring you to Pyramid Area 1 on first visit and Pyramid Area 2 on second visit,
2nd Totem bring you to Aquarium Area 1 on first visit and Aquarium Area 2 on second visit,
3rd Totem bring you to Dinosaur Area 1 on first visit and Dinosaur Area 2 on second visit, and
4th Totem bring you to Galaxy Area 1 on first visit and Galaxy Area 2 on second visit.
You know, something like Megaman 8 having the alternate bgm when you die in Tenguman's stage.
That's all I can think about. Maybe it will be too much to ask for v2.0. Maybe next time if you decide to further expand it to v3.0.
