Karatorian just a reminder to please check world 4-2.. it looks like there's some corruption at the end of the level. it's past the flag but it looks like you could jump over the flag using hidden coin blocks and get to the secret area which i think says "HELLO" but all you can see is "HEL" lol

Hi Guys, I'm the one on the Digital Press board who got to 4-4 and also discovered the hundred lives trick and the glitched level 4. It's the same as in SMB but WAY easier to pull off. You can do it on flat land! Just jump on a turtle right next to a wall or block and rack em up. BTW, please thoroughly read the thread on DP. There is one level in particular that you CAN NOT pass unless you allow an elevator to drop of its track. This is either a glitch (HIGHLY DOUBTFUL) or extraordinarily sadistic programming. Man, I put some blood, sweat, and tears into figuring that one out! Also, I forget which level, but there's actually places where you can go down a pipe and be stuck until the time runs out. At least, I didn't find any way put. But yeah, please read the DP thread. http://www.digitpress.com/forum/showthread.php?t=83082By the way, when I discovered the Bee, I didn't see any way that it was a continupower up, iirc. I remember even holding either button and start like SMB, and left and start like Milon's Secret Castle and Hudson's Adventure Island. I don't recall any effect. -Rob |

hey rob yeah I did read that thread. I suspect the problem you had in 4-3 is some kind of weird glitch more than anything deliberate. Especially since there seems to be corruption in 4-2 and 4-4, perhaps 4-3 also has some issues?

You could be right, frantik, but I think the code really needs to be examined to determine this. It would be a shame not to include such a dastardly feature in a remake if it were purposely put there. As insanely difficult as this game is, I have very little doubt it was put there on purpose. I'll check to see if there's a Youtube of 4-3 to see if others had the same issue. It seems someone was already playing with an uncorrupted version in order to make those videos. There must be a clean dump out there, but I haven't found it. EDIT: http://www.youtube.com/watch?v=HzQbj-DXj64The elevator drop to make the platform appear in 4-3 is not a glitch as far as I can tell, because in this video you see the player exploit an entirely NEW glitch to get past the point in question. Apparently, he didn't figure out the technique I did. I think I spent 200 lives figuring that out! Oh, and the complete 4-4 is shown, in case anyone wants to check to see if it was fixed correctly. -Rob |

yeah i watched that video last night to see if a) there was the bonus part of 4-2 shown and to see bout the platform thing in 4-3 but the guy uses some glitch to get thru the whole level so it doesnt help one way or the other lol

About the dead end pipes, I haven't run into them in the game, but from my testing of the level data, I know what causes them. In the level header, the pipe entrances have an entry that tells where they drop you and such. If an enterable pipe (they're marked with different blocks) exists on a chunk that doesn't have an entry defined (or the entry is somehow invalid), you'll get stuck.

Have you decoded the pipe info? it hasn't been an issue yet but in 4-4 there are lots of enterable pipes so it would be good to know which ones lead where

According to that DP post, there is a Sharp X1 version of this game too. Really wish I could find that to compare!

Yeah, I've decoded the pipe info. I intend to make my level dumper create an info text file for each level that includes a human-readable version of the header info, including the pipe data. I haven't gotten around to it yet because I've been working a lot lately.
I took a look at the corruption in level 4-2 and I found the strangest thing. You know how I mentioned that the 4-4 corruption was caused by the data being shifted right one bit, well the 4-2 data was shifted right half a bit! Well, not really. Floppies use MFM encoding, which stores two bits (data and clock) for every one bit of data. Apparently, the drive got out of sync and started reading the clock bits, rather than the data bits.
I was able to confirm this by manually restoring part of the level. I could see pattern to the corruption, and I had a good idea what the next few columns of the screen would look like, so I was able to manually contruct a few columns. This gave me a data set to compare to the corruption. After messing about, I remembered that magnetic media don't directly store bits on a one-to-one basis, so perhaps that was a factor. As it turns out, it was.
(In fact, the part of level 4-4 that I couldn't identify the pattern of corruption was the same thing. Not that it mattered in that case as that part was very simple, so I could just reconstruct it from scratch, but it's good to know.)
I haven't applied this info to make an uncorrupted version of the level yet, but that's my next priority. Unless I run into trouble, it should be sometime tonight.

Hey guys, when this is done, It would be really cool to make a guide of this game using screen grabs (or simply long jpgs or whatever of the complete stages) and with all the special hidden items and such mapped out. It would make a great faq, since I highly doubt that a book or maps or anything on this game even ever came out in Japan.
