| http://s91407720.onlinehome.us/acmlmboard_files/romhacking/yi/idozerss.png I have been working on this in a sporadic manner over the last several months. It's just a viewer now, but I'm excited that it shows something that is somewhat intelligible. I relied on public docs to do this. I'm not very good at doing my own reverse engineering. It probably does not help that most reverse engineering tools are Windows only. EDIT: Inline picture is now a link. (edited by Cellar Dweller on 07-14-04 01:57 AM) |

| A Yoshi's Island map editor? Well, that's what the name suggests anyway. :o Altough that does look weird for a YI map. Must be because it consists out of squares and such. :o |

| Hmm... with that other Yoshi's Island editor, and if this is Yoshi's Island... I'll be able to hack it! However, Coby's right, it does look weird. |

This is a major step forward CD. Thumbs up!  @Coby: maybe that's because he didn't bother decompressing the graphics yet? If the graphics can be decompressed already, just imagine this same editor window but with the graphics in the right places. That's the real progress right now. Many many kudos to you CD  |

| It appears to be an editor for something like one of the Adventure Island games. Actually, the game which really comes to mind is Ufouria. Well, that's because the it looks similar to a Metroid-style map. Which Ufouria definitely has. And maybe just the personal opinion that the game should have a very nice editor. *shrug*  |

| Looks like the last part of 1-1 in Yoshi's Island to me ... Reminds me of when I was just starting my SMB3 editor and hadn't worked on showing graphics yet, even my SMB2 editor started as a viewer that only showed squares  But it's a start, and a good one (edited by Acmlm on 07-12-04 11:42 AM) |

| The problem about it, for me, is that it looks too much like Linux... and romhacking hates Linux. That's fact. Is there any chance of porting it to Windows before it progresses too much? ...and the screenshot reminds me of a YI level. I believe it is 1-7, the one with the weirdo drug things flying around. Need any help? I am currently not quite busy with SST and SMW-ALTTP Have fun, Blacky. |

| 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. | |||

| 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? |

| 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. |

| [small hijack] ...and romhacking hates Linux... 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 [/small hijack] 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)  |

| 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. |

| "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 |

| It looks more like a Tetris Editor than a YI editor to me. This editor only displays basic shapes that represent the environment. SMW is hacked so much, I'm sure you could find a full YI editor out there, it is a similar game in a lot of technical aspects. |
