That is not the program I posted screenshots of. It is just a little command line tool to edit level headers. I linked to it in a reply to a YI data thread before the database wipe. No one seemed to be interested in it, and the contact information(a pre-wipe PM URL) included is out of date.
However, the header encode/decode functions were copied into Island Dozer. |

For crying out loud glance at the url for once!! |

I seem to have encountered an new(or at least unwritten of) form of 4 byte object. They are like the standard 4 byte objects but the last byte is not a packed width and height. One dimension is fixed in size and the other is specified in the (entire?)last byte. Lines of coins, wood platforms, and pipes are some of the objects that appear to work this way.
A few objects are 4 byte that were thought to be 5 byte. The ones that I changed to stop junk decodings: C5 C6 C7 F4. There is probably more. Some objects were listed as both 4 and 5 byte, or not at all. I have made some guesses about some of their sizes. If the program encounters an object with an unknown record size, it will stop processing objects and print the unknown object command on standard output.
Ailure : It is written in C. The GUI is GTK based and designed with Glade. I'm using Anjuta for an IDE. The versions of Glade and Anjuta that I'm using are both pre-1.0.
If I get it released, it will be available of Linux first. After that I hope to port it to Windows, and if I don't, I intend to release it with the source code anyway.
HyperHacker : You did. It is in this YI data thread.

Yeah, let's install Linux ONLY because we want to make YI hacks.
or how about you're grateful that someone with skill is actually doing anything at all.
you can progrm in hex ONLY, because you're not grateful |

Sorry if this is a useless post, but I'm pretty sure I posted the header format. If nothing else I can get it in September. |

Not really a big deal to bump a data thread, as long as you're contributing significant new info to it.

Ok ok, I was mistaken. I have never heard of any full YI editor, It was a mere assumption. So yeah, I'm wrong. |

Go find us a full YI editor then We'll see ya in a few months, I suppose. |

I supposed you would have to crack open the source of the ROM and modify the code if you wanted a YI hack. I am aware of the fact the graphics are still compressed.  |

Uhm.. No.
It's not all THAT easy. Else we'd have an editor for a looooooooooooooooong time now, and the squares are there because he doesn't know how to extract the GFX from the ROM yet. |

Besides, most Linux apps are portable to Windows, I really doubt this would come off as Linux only.
What is it programmed in? |

"Would it be considered appropriate to bump the Yoshi's Island Data Thread? I have (re)found some of text, including level names, that were not mentioned in Iggy's docs."
I think that having all the YI data in one thread would be better. And I think the Rom-Hacking mods would be pretty understanding. Hopefully 
And everyone's free to program for whatever OS they want.
It just gives me yet another reason to install Linux |

I tried changing the pointer to 1-1's objects from 0x1681c7 to 0xcb01c7 in the level table and it worked!  That probably means that banks 00-3f(and 80-bf) should be treated as LoROM and other banks should be treated as HiROM.
...thinking...testing...
The YI ROM is 2MB so it fits exactly in the second half of banks 00-3f. It also fits HiROM style exactly in banks 40-5f.
Are some of the level pointers pointing into the HiROM area because level data processing will pass across bank bounds or wrap around into RAM? That doesn't appear to be the case for 1-2. I changed both of the HiROM sprite and object pointers to their LoROM equivalents and both still worked.
I don't know why Nintendo would mix LoROM and HiROM pointers in the level list when only using HiROM pointers would work for sure. |

Wtf? 
People are free to use any OS they want, that's the very true meaning of GNU-Linux. Plus it's my OS of choice

I think it is not that bad bumping an old topic, even less bad if it is for a good cause (or a very good one like this) |

In case anyone still isn't sure, it is 1-1 from Yoshi's Island. The rectangles are drawn based on the information in the object list. The slightly shrunken squares are sprites.
The program has no knowledge of the actual dimensions of the objects, which can differ from the size stated in the level data. The big faceted rocks are extended 4 byte objects, so they show up as 1x1 squares. The horizontal wooden platforms near the beginning of the level have their length stated in their height field. The diagonal line of coins object in this level has a height of 111 (0x6e in the data plus one).
Sadly, it looks like special cases will need to be created for each type of object. Each case would interpret the location and size fields, and then pick out the right tiles to draw the object. If you know better, please speak up, especially of you have started a successful editor project.
I'm still not clear on how the memory map works. I know that if the pointers to 1-1(LoROM) and 1-2(HiROM) are swapped, they will still load and work, suggesting that there is no switching between LoROM and HiROM. The LoROM and HiROM maps conflict about what should be mapped in some places(eg. the second halves of banks 00-3f). Yet, according to some discussion(lost in the database wipe), utilities such as Lunar Address will be able to compute the correct offsets in the smc file. Could the 1-1 addresses be traslated from LoROM addresses to smc offsests and then translated to HiROM addresses and still work in the level table?
Would it be considered appropriate to bump the Yoshi's Island Data Thread? I have (re)found some of text, including level names, that were not mentioned in Iggy's docs. |

Altough that does look weird for a YI map. Must be because it consists out of squares and such. :o
That last part sounds very much like "omfg squuuares ", and that made you look very stupid. |

Either the sizes are wrong, or it isn't.
(1) The floating rock is definitively too high.
(2) Where is the rock wall right of the floating rock?
(3) Where is the wooden ledge below where the rotating platforms should be? |

It is Yoshi's Island. Look at the level. It's towards the end of 1-1 Make Eggs, Throw Eggs. You know, the part with the beanstalk. |
