Yet another video of glitches. I'll find them all eventually. =P
Anyway, this one has some tricks in the Cossack 3 stage (mostly in the boss room), and also two small glitches after beating Wily at the end of the game. Dr. Wily has quite a high ceiling in his lab.
Just relax guys. I will have this lag thing all figured out. In fact music actually causes lag in the game because of the extra calculations that the game has to perform (the music/sound addresses are in 00070X). Also I figured out why there is lag every 8 pixels you advance and that is because the graphics on both sides of the screen have to change which is also a factor in the number of calculations in the hex addresses.
As a result, I have come to the conclusion that the more stuff that the hex addresses have to do over time, the more likely there will be lag later on in the game.
I still never figured out why Mega Man 3 had to be so laggy (I honestly tried many times to improve Top Man's stage but no matter what I just couldn't improve it)! :( Oh well...
Kind of an ingenious theory on lag don't you think? ;)

Yes your 100% correct glitchman.
Music and screen-drawing stuff is pretty CPU-intensive. music much more. The music engine can take anywhere between 10 to 70 or more scanlines of time, just to process in 1 frame. This applies to megaman 3 to 6. (NES has 240 scanlines before the next frame starts)
Over all the years i've been doing my megaman 3 rom hack, i've always been literally finding more and more ways to shortern routines wether it'd be something originally in the rom, or something new i coded myself. And i always make fceux video's of myself testing areas when i manage to make a routine shorter, or more efficent vs. before i did, using the Lag counter, i'll see that my game starts to lag a couple frames less each time. It's pretty cool.
On average a un-modified megaman 3 rom with music turned off, pallete animations off, and just standing still in a level without touching any buttons. Average time it takes for a frame to process is about 90 or so scanlines, while my game averages around 45-50. :)
Well, since Glitchman doesn't want to submit his Mega Man 4 run (=P), I decided to start doing my own.
Of course, this isn't a speedrun because I'd get bored of it. Instead this is glitchy, quirky and silly.
This is also my first time I'm posting a WIP, and I'm a n00b that doesn't know how to use the Microstorage so here is a link for Speedyshare.
Comments, opinions, etc? Also would someone mind letting me know about the Microstorage?
I also tend to keep my projects private, so I'm likely not going to be putting up any more WIP files until the whole thing is done. =)

Select your file. Leave a comment. Hit upload. Copy the url on the next page to us.
Uh, yeah that's about it. No file managing or anything.
I came across my Theory of Lag when I was playing Mr. X Stage 1 from Mega Man 6 and I was in the fifth room (the one that has the breakable window). At that room I was facing the left near the edge of the screen and doing turbo A & B. I noticed that when the song changed to the next portion there was a frame of lag.
That was some very useful information on how lag in an NES game works kuja killer. T3h Icy, don't worry I will definitely submit my run tomorrow! :D
Also about submitting my movie, it's not that I don't want to submit it but I want to find a perfect time for it and tomorrow is the perfect time for it! :D
I have to ask though, did you ever try out if Dust Crusher is faster on Cossack than Mega Buster? I've been going through the game a lot for awhile and that's the only thing I've come close to in finding a large change that would lower the overall time.
Do you know or have a way to prove it'd be slower?

Cool, I'll be sure to watch it.

<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.
So are you still going to be improving the run Glitchman? I'm also still looking for neat glitches, but I haven't really found anything worthwhile for a bit now.
Excellent. I expect your next submission to save 5 minutes.

Well...that's seems like a bit much. That would mean saving 18.75 seconds per stage which is a lot in my opinion! I was expecting to save 3 minutes at the most but we'll see what happens. You never know! :)
Remember, we have to take into account how many time savers there are and how much time each time saver would save.
...Unless you found a time saver that would save a great amount of time (let's say...two minutes)! :D
I've got it!

It turns out that the pause/charge glitch did give me an idea for one boss and that boss was the Wily Stage 1 boss (Giant Met)! I knew finding gameplay glitches/tricks on the YouTube would help me out! I was able to fit in two more 3-damage hits from the Mega Buster as a result allowing enough damage before the Giant Met hides in its helmet!
=D
How much time is being saved through that though?
Not sure...but I'm hoping to improve this (weapon switch reduction is key)! :D
Anyway, I am glad you like this! I'm hoping to find more improvements/time savers! :D
