<adelikat> In Oregon Trail, I sacrificed my own family to save time. In Star trek, I killed helpless comrades in escape pods to save time. Here, I kill my allies to save time. I think I need help.
HOLY HOLY HOLY SHIT!!! Dude... You have to tas the whole game. That was beyond awesome. How the hell did you manage to avoid getting killed being in the wall? Through those pauses? As I am sure you know, you normally die after your invincibility is over upon being inside a wall.
Edit: mtvf1, you need to contact Tiancaiwhr for this :D
Don't warry, Tiancaiwhr left the Diveman to the last, so it's not need to redo the most. It's seemed use this trick on the other place, megaman will die.

For reference, this huuuuge new discovery saves roughly 2 minutes!

So, is anyone doing a new run currently? Me, TehSeven and thelegendarymudkip started running this game a while back, but we got stuck without recording too much.
I managed to figure out the RNG calculation, so I thought I'd share the info if anyone needs it.
The RNG is located in four bytes at
E4 E5 E6 E7
Every frame, the contents are shifted right one bit. For example
0000000 11111111 00000000 11111111
would become
1000000 01111111 10000000 01111111
The new leftmost bit of E4 is created by XORing the second rightmost bit of E4 and E5. Bolded above.
How is the RNG used? This has not been extensively tested, only for the birds in Pharao Man stage. For these, the frame when the egg drops start, the game reads E7 and uses it to determine the random action, in this case the number of eggs to drop. (1 egg 50%, 2 eggs 25%, 3 eggs 25%, in case you wondered.) It then writes to E6 and E7 in an unknown way. Feel free to figure it out. But it's dangerous to go alone, take this: http://nesdev.com/6502.txt
Can the player influence RNG? Yes. Both directly and indirectly.
- Indirectly, by waiting for one or more frames before scrolling an enemy into view.
- Directly, by shooting and sliding directly after each other. This locks E6 and E7 to a value dependent on which weapon you are using. For example, the mega buster locks to 0x05 0x05 and 0x85 0x05 (switching between them).
I have not seen E4 and E5 being written to. If this is indeed the case it means that all changes to the RNG are temporary, and get shifted out of the RNG in 16 frames.
Since the RNG is otherwise deterministic according to the formula above, it can be detected when the RNG was written to and didn't change as expected. Here's a lua script for FCEUX which does that, marking the addresses which didn't go to the expected value in red:
http://tasvideos.org/userfiles/info/24508776408376192
It's pretty crappy, but it gets the idea across. If you want to improve it you could add lag detection and load state handling. These give false positives at the moment.
Good luck, feel free to ask if something is unclear.

Truncated, mtvf1 said Tiancaiwhr had reached Cossack stages. But he also noted that Tiancaiwhr is quite busy with real life. I figure maybe mtvf1 could ask Tiancaiwhr to send the wip and you guys could finish it up.

Don't include lag of luck manipulating?

I figured out how the RAM addresses 80, 81, 84, and 85 can be helpful in determining luck manipulation. In normal gameplay they all equal 01 but when a lag frame occurs they equal 02, 00, 04, and 00 respectively. Most of the time there won't be a frame of lag when only one set of them doesn't equal 01. I can use this as a form of luck manipulating.
I also noticed that when 83 and 84 equal 02 and 00 and the same values switch to 80 and 81 one frame later, it is a frame of lag. There are a few instances where all four RAM addresses equal the 02, 00, 04, and 00 values there isn't a frame of lag. This can also help me study the lag better and know how to control it better.

Thats very cool to hear mtvf1. So is she now actively working on it?

This looks pretty tempting to see. I do remember working on this game many years ago with a little bunch of people but we stopped making it somewhere along the road. I'm also glad we can utilize and exploit this game by using a wire which makes things even more interesting. Let's hope there will be more tricks to see! It's also a bit random because these kind of tricks are somewhat similar with Mega Man 5.
would you upload your moviefile or a video so we can check it later?
I want all good TAS inside TASvideos, it's my motto.
TAS i'm interested:
Megaman series, specially the RPGs! Where is the mmbn1 all chips TAS we deserve? Where is the Command Mission TAS?
i'm slowly moving away from TASing fighting games for speed, maybe it's time to start finding some entertainment value in TASing.

A completely new route？
The route is same as WIP1.7.0.
Thank you for your support！

Hah.. Maybe he misunderstood you, or something. Anyway, are you uploading to youtube? 'Cause I really want to watch your run ^_^

I made a full-game playaround TAS of Mega Man 4, check it out! Rather than purely focusing on speed, this involves messing with glitches, oddities, tricks, and other shenanigans!
I highly recommend watching it in 720p60 for 60FPS.
