.sb3 files are useless that .sb2 files are better because scratch 2 startup very quickly
You can ONLY open in app for scratch 3

when green flag clicked
say [This is the blocks for Scratch 2]

-Rex- I did your project in exe format, I think it will be better for people who do not want to download python just because of one application, here is the link → https://github.com/SAnABros/SB3-to-SB2

I've just finished writing an SB3 to SB2 converter in Python 3, which can be found here: https://github.com/RexScratch/sb3tosb2

If you find any bugs or issues, please tell me. This is also the first time I've written something like this, so I'd appreciate feedback on how to improve the code.

But how do u use it (is it flash, exe file, html web thing?)
EDIT: ohh its python

i'm trying to find a converter

game_pr0grammer

can you do .sb3 to .xml for snap

I tried to convert one of my projects using this and found that most of the music didn't convert. Everything else converted successfully. I am confused as to why it would be doing this.

Nevermind, I figured out the issue! It should work flawlessly after my fixes, I'll post an update when that is.

It works the way I wanted it to. I just had to convert the music into the .wav format from .mp3

md5ext = c
KeyError: ‘md5ext’

How to resolve

I have the same problem!
The problem is caused by, in some case, there is no “md5ext” key. This key contain the file name of the Costume!
File name of the Costume, can also get from these 2 keys: ‘assetId’, ‘dataFormat’!

I just do the following, then solve the problem:

In function 【def addCostume(self, c):】
1. replace the code line 【md5ext = c［'md5ext'］】with【md5ext = c［'assetId'］+'.'+c［'dataFormat'］】
2. replace the code line 【f = self.zfsb3.open(c［'md5ext'］, ‘r’)】with【f = self.zfsb3.open(c［'assetId'］+'.'+c［'dataFormat'］, ‘r’)】

Sorry that, I don't know, how to show “Open bracket”, “Closed bracket” here.
So, I just replace “Open bracket”, “Closed bracket”, with it's Chinese counterparts “［”, “］”!

try this (I am using win7、win10 OS. and python-374.):

Create a run01.bat file, have the following 3 code lines:

set py3_exe=“D:\python-374\C_Users_user_AppData_Local_Programs_Python_Python37-32\python.exe”
%py3_exe% sb3tosb2.py -c xy.sb3 xy.sb2
pause

where,
set py3_exe=“D:\python-374\C_Users_user_AppData_Local_Programs_Python_Python37-32\python.exe”
should be changed to your python executable path.

xy.sb3 is your .sb3 file name.

xy.sb2 is .sb2 file name you wanted.

Put files “sb3tosb2.py”, “xy.sb3” , “run01.bat” in the same folder.

Execute run01.bat file, and, see what the error message is!
