The volume isn't even low enough to make a difference, I could hear the stage music just fine.

Here's a question. Is it possible to wobble zip in a solid wall without constantly jumping to keep X from getting stuck? If you can, I have some more ideas on potential zipping areas. Edit: Nvm, I don't think it is possible. I was going to try zipping from the arm capsule to the subtank in Mammoth's stage, and again from the armor capsule to the tunnel below in Chameleon, but they don't work it seems. The only other Zipping areas that MIGHT save time is zipping into the boss door that leads to Vile from directly underneath and the same for the Kuwanger refight and Rangda Bangda boss door, but I don't think they will work either. Other than that, Downward zipping after the Chameleon and Mandrill refights MIGHT save time, but it's kind of a stretch. The only one I can see saving real time is that first wobble zip after getting the subtank in Mandrill's stage, then possibly the second and third shown in that video I posted earlier.

Okay, so I'm working on a complete disassembly of Mega Man X right now. I suppose this could prove to be useful to some people around here in the long run, so I was wondering if anybody wanted to help me document RAM addresses? I have a WIP RAM map right now, but it's pretty small thus far. I'll post notable findings here, if people want me to.

If you don't mind me asking. Hows the run going guys, have you made any progress? If so can we expect a WIP anytime soon?

Thanks for the RAM map - it has been quite useful for me already. I have a script which draws graphics on top of X, and while it usually works fine (as long as I calculate X's integer position as xint = (x+0x80)/0x100, that is proper rounding for subpixels instead of truncation), on some frames the screen scroll value in address $7E:00B4, $7E:00B6 is off by one pixel. This happens a lot during the intro stage, for example, where you will see the x scroll value stand still a few times even though the screen moves every frame. This seems to happen in busy areas, so perhaps it is connected with lag. So there is probably another set of scroll values somewhere in memory which corresponds to the true scroll. Or perhaps there are scroll sub-pixel values somewhere, and the scroll must be rounded just like the X position is. Another nice thing to have in a RAM map would be delay information. I.e. for addresses which correspond to visible changes on the screen, what is the delay between the address changing and the screen changing?

I refrained from posting about it for the past year, but I'll delude myself no longer and be blunt about it. I am not working on any Mega Man X TAS. I will not continue the latest WIP. Rolanmen1 is not working on it either.

Well, i was planning on moving the run to BizHawk by hex editting it, if that's possible, if it is, it will take too much hex editting, depending if BizHawk is more or less laggy. However, this doesnt mean that either me or FractalFusion will work on it afterwards.

Heres a good tip. In boomer kuwangers level (I CAN ACTUALY SPELL HISNAME!? O_o) *ahem* ANYWAYS in Boomer Kuwanger's level, during the elevator segment, you can charge a Rolling Shield and make the climbing section with the moving platforms much easier, since running into the enemies like this will just destroy them. Also, by hopping off the side of the retracting platforms you can probably jump on to the ladder quicker. I dont know if that second tricks been used (forgot from the megaman x speedruns ive seen and cant check cause im in school :P ), but the rolling shield should make it easier to manage, and quicker, since you wont have to figure out how to hit the lizard on the ladder without losing time, you can just run into them. And there is a great chance to charge it during the elevator segment, which just happens to be before the climbing segment, so its perfect! On a side note, there's a guy named Kevyll on youtube who did perfect runs of every megaman x game meaning no upgrades, no damage, buster only, no special weapons, no charge shots, and (in x1 only) dashless (even though acquiring the dash boots is required). I would like it if someone TAS'd MMX1 along those guidelines. it would be long, but cool.

I quit TASing.

I believe that the buster upgrade is skipped in the current run, since you get it automatically in Sigma 1 anyway. That does mean that charged weapon attacks are unavailable for the normal levels though.

Besides, Boomer Kuwanger is done second in the 100% run anyway. Significantly earlier than Armored Armadillo.

In x1 how does he kill final sigma? In x2 how does he kill Agile, Zero, and final sigma? Being that none of them can be damaged from an uncharged shot or use of a special weapon.

But that's a special weapon. The above posts stated no special weapons.

Oh he didnt do sigma stages, just the maverick and intro stages. However, you can probably make an exception for wolf sigma (he did for duff mcwhalen, since the whalebot mini bosses are so annoying for him) and fire the charged shots there

I quit TASing.

Just for that little bit. The rest is all uncharged and no damage or upgrades, or special weapons. Id do the run myself, but i have a lot more runs to do, and i like playing x with a wiimote (hombrew channel emulator) instead of a keyboard (awkward controls).

I quit TASing.

Ya, I am able to do that for x1 and x2. A guy named RoahmMythril did all of the classic MM series that way. But did not do the wily stages because it would force him to use rush/special weapon.

Im saying there can be an exception if a charge shot is actually required and etc. And yes, I checked the damage data chart, and wolf sigma can only be damaged with level 4 charge shot or rolling shield (which is out of the picture cause of no special weapons), in case you thought i didnt know.

I quit TASing.

Kevvl breaks the charge shot rule a lot. He ditched the rule completely in X7 and X8, which is good because it just drags on without it. Anyway, just watch HideofBeast instead. Complete with great gameplay and excellent commentary, you can't go wrong.
