Overworld Map Corruption in FF6LE
« on: August 20, 2011, 08:50:42 PM »
Somewhere along the lines my WoB and WoR maps became corrupted and uneditable in LE. I get an error the moment I open the LE from Microsoft .NET Framwork, that tells me:

"Unhandled exception has occurred in your application - Value of '9' is not valid for 'Value' 'Value should be between 'Minimum' and 'Maximum'"

I just click continue... The overworld maps don't display anything but really messed up and garbled tiles, and when I try to do any editing on them, like make a house tile, or a tree tile or anything, when I save I get a error that says it cannot save or something like that. The overworlds look fine in the game though, and all the other maps work and can be edited in LE.

I have tried the other level editor as well, and while it does display the maps correctly, it does not allow any editing to be done on them either. I came to the conclusion a while back that it was something I did in USME that may have caused it to do this, one of the patches applied maybe causing a conflict with LE. I'm not 100% sure on this, and I think the problem does not pertain to the latest version, as I cannot seem to replicate it.

My question -in short- is, is there any way that this can be fixed so the overworld maps will once again show up in LE, and are editable once again? And so that the opening error will go away as well. I'd love to be able to edit the overworlds again.

That's a pretty generic error windows gives with this editor. Unfortunately, it helps not. Not really sure where a 9 comes into play.

Considering FF6LE doesn't touch bank F0 (or even make one for more map data) I find this to be unlikely.

Copy the original world maps to your hack, see if that still works. If it does, your map is bunked.

I got this problem constantly if I added too much dialog to the game with Yousei's old editor.

Thank you, and did you mean to try the LE's import/export map feature, or locating and then re-inserting the binary data for the overworld maps in the F0 bank? LE's import feature is not working with this unfortunately,
and hardly ever seems to work for anything else either. I clear the map and import the map from a clean ROM, and it does nothing noticeable, so looks like I'll have to try the later option. I haven't seen the map data documented before anywhere, does it exist somewhere so I can pin down the exact maps I need to copy?

Today i've had another person also say it's because of USME. and, is there any chance you may be able to follow up on my other question? I would appreciate it, as it seems any other question I ask other than the 1st one always get ignored.

I've experienced things like this before in the past too, but not with the LE (which I've not really used) but with the Yousei editor.

Still trying to desperately figure this out, I took a look at the 'Manage expanded ROM' section in USME,
and noticed this -

FF3Edit Map Graphic Expansion

HOW AN EXPANDED ROM WITH WORKING OVERWORLD MAPS IN LE LOOKS:

Regular section usage:
WoB Map/Tiles: $EED434-$EF324F, 24092/24092 bytes
WoR Map/Tiles: $EF4A46-$EF9D16, 21201/21201 bytes
Mini maps: $EFE49B-$EFED25, 0/2187 bytes

HOW MY ROM LOOKS:

Regular section usage:
WoB Map/Tiles: $EED434-$EF324F, 24021/24092 bytes <-------- missing bytes
WoR Map/Tiles: $EF4A46-$EF9D16, 21201/21201 bytes
Mini maps: $EFE49B-$EFED25, 0/2187 bytes


So in the WoB Map/Tiles, there appears to be some tiles, or bytes that are missing?
Could this be what is causing LE not to show the maps and all my grief??

I then copied the data from the working expanded ROM over to my hack, and opened LE and sure enough, it showed the maps again! OMG, I got so excited, but then when I went in to test in-game...the game becomes corrupted upon showing the overworld maps. It either just goes all black, or some really messed up tiles everywhere.

Sooo with my data how it is in my hack, the overworld maps are uneditable/don't show up in LE, but work just fine in-game. But if I copy over how it original should be, it shows the maps in LE fine, but corrupts my freakin' ROM.

Not only that, but then when I checked in
FF3Edit Map Graphic Expansion again, it showed:

WoB Map/Tiles: $EED434-$EF324F, 15643/24092 bytes, so that's why the corruption obviously, transfering the data over somehow made tons of tiles and bytes vanish, but it fixed LE being able to show and edit the maps...huh.

I am at this point very confused, but have not given up, I feel like there's still hope.
ANY more insight into what may be going on or an idea how to fix it still would be most welcoming.
I'd much love to resolve the issue, and be able to edit the overworld maps once again.

I had the same problem. As soon as I was modifying something with usME, the next time I opened LE al lot of the overworld map tiles were glitched and the tileset in the upper right corner of the editor was all messed up. I don't know if in game the map was fine as I haven't checked that.

I did some experimentation too and I managed once or twice to succesfully patch a ROM that was modified with usME with a patch that was made ONLY of the changes in LE and then the overworld maps in LE were still editable and looked fine (again I don't if the map in game was correct and this "technique" doesn't work if you edit other maps in between). If I was using usME after I was corrupting the maps in LE again . I don't remember If I was using an expanded rom but I think so.

My only option was to modify at first the overworlds maps and create a patch and then start(again) my hack.

You probably localized part of the problem and I'll try to figure it out on my side as soon as I have time.

Serpent Trench Map Corruption in FF6LE Rogue
« Reply #9 on: February 17, 2012, 09:02:40 PM »
Well since it's a LE map corruption thread this is more than adequate:

So I've been creating npc among other thing with the "new LE" for the past two weeks and realized that there is bug that corrupt your Serpent Trench map whenever you save; saving without changing anything, saving after a slight modification or an heavy one. The bug is also there if you previously save with FF3usME. Anyway, someone pointed it out to me first and my ROMS where affected by it but maybe it's something we do that we shouldn't do.

I ran a IPS report with a fresh new corrupted ROM and seems the WOR and WOB map data get swapped and this would be normal as this version is suppose to be compatible with FF3usME that swap those too. One thing that bugs me is that the Serpent Trench map data is also moved or maybe there is a byte shift I can't tell as I didn't check in details the changes when you save. Could someone that has worked with the Rogue editor deny or confirm this? The map really look like garbage and you get a black screen whenever you try to enter the Serpent Trench by the Veldt cave...

I wanted to post that on Mnrogar as there was a thread on the new LE and Lord J post there sometimes but I'm not registered. I sent an e-mail to Lord J Monday and I haven't received an answer yet.

Thanks
