File “C:\installables\sb3tosb2-master\sb3tosb2-master\sb3tosb2.py”, line 1481, in addCostume
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 “［”, “］”!

Dude then the python file doesnt even open.

Do you have replace Chinese character “［”, “］”, with it's English counterparts, “Open bracket”, “Close bracket”?
Also note that, Python program is sensitive to Indention!

Today, I go to sb3tosb2 official site (https://github.com/RexScratch/sb3tosb2). I find that, sb3tosb2 has been modified to reflect “md5ext” issue.
So, you just go there, download new version, and try it!

2. I did let it fully load. The X,Y coordinates were moving (when my mouse moved) and only a default project displayed for over a half an hour.
3. I have now tried with multiple projects to get the same result of a blank project file.

i use it too!!!!!

Your Python version is outdated. Try using Python 3.6 or later.

Electroboss

wait where's the python file?

Electroboss

OH! Found it.

Wow! Super cool program!

i clicked clone or download then opened the file and opened the python file then it just opened python editor. I clicked run and nothing happened it just seemed like some kind of shell?
