While YY-CHR is a very nice tool I am unable to contact the author in any way to request a feature. If anyone knows him/her or can contact the author. I'd ask for a multiple file support in a single instance of YY-CHR via tabbing. This would make life so much easier.

Please Read:

In the previous hosted version of yy-chr there were some QoL changes made before reuploading, mainly setting the default save type to not ask to expand, which was not carried over to this version.

To correct this either download the previous version, which even stated in the above description *No update of YY-CHR.net this time.*, has the same yy-chr version.
Or go into Options -> Settings and find SmallFileSaveSize and set it to NoExpand.

This build is great! I like the new image pasting enhancement, although I wish you could overwrite the palette with the one recognized in that paste optimized image menu.

Replace the CharactorLib.dll file in the YY-CHR folder with this to set 4BPP SNES to the default for .bin files.

Apparently the extensions for each format is hardcoded into this library as strings, and the format resets to the first format that accepts the file extension when you open a new file; so I just hex edited the library so that 4BPP SNES becomes the first format for .bin files. If you've got other needs, I suppose you could just hex edit the library yourself (just search for bin - note that characters in strings are padded with a 00).

Note when working with SMW bins, the .NET version will claim each time you save that the file is too small and needs to be expanded and you must say NO to this to keep the file the correct size. Since this problem was in the previous version and is mostly an annoyance and the author is not present, accepting the update.

This supports 8bpp!(But only Mode 7)

I have been waiting for a zoomable YY CHR my entire life!!

I tried to add zst file for colors, but it's not working, I don't know why.
EmulaDuck From older version: YY-CHR v0.99 (.NET Version, English) Link
Nothing is edited, insert, save and try everything but still not change anything #smw{T_T}
For example, I edit the overworld but it remains exactly the same, or I have to use another tool to edit the overworld, because for example I want to add pyramids but even if I edit they do not add me and when I open the file again I do not edit anything

After all my files vanished into the big black void of nothing on my old computer after dying out, I've been all over for this again ;-;

Updated the website link. Somehow overlooked that.

As for "opening in two applications simultanously", that's not a "software glitch", it's just common sense. Opening a file simultanously in two different applications in write mode will always lead to chaos, just don't do that or else you'll be responsible for everything bad that happens. For this purpose, most applications that open files for writing also automatically lock them (in fact, I think Windows does that automatically, which is probably why YY-CHR malfunctions, since it can only open the file in read mode after it has been opened in write mode by the hex editor).
HammerBrother From older version: YY-CHR v0.99 (.NET Version, English) Link
There is a nasty software glitch where if you open graphics files with a hex editor (wxhexeditor), and open it using yychr (2 programs using the same file), yychr won't open it correctly. Also, why isn't this website query isn't link to this website: http://www.geocities.jp/yy_6502/ ?

Jack is no good at moderating tools. :x
I mean, come on, you didn't even fix the author.

Fixed author, name and description.

Anyways, who didn't rename this .NET version?

@Konata Izumi

I am telling people not to use this badly designed tool, and to use a better designed tool instead.

@MarioFan64 cool, what is that even relevant to?

still far inferior to the standard graphic editor: https://www.smwcentral.net/?p=section&a=details&id=15530

Err. This is the .NET version of YY-CHR. It's different in some regards to the original, not .NET version we host here. It lacks the stamp tool for example, but it's an overall improvement of the original.

Anyway, this isn't YY-CHR v0.99, it's YY-CHR.NET.

I guess this is nice for anyone who has issues with other version.

Why not to mention YY Creator in authors? Because he/she made main tool.
