Hello, 

The tool loos great and I'd love to try it but I am getting the following error : 
"The procedure entry point inflateValidate could not be located in the dynamic library C:\[userpath]\files\pyxel\core\bin\win64\libpng16-16.ddl"

Hello, Thank you for the report!

Actually, you are the second person to report this issue, and I have been investigating it, but the cause is not well understood. It seems to be reproducible depending on the PC environment.

I would appreciate it if you could tell me the details of the PC environment. And is it a normal PC or a development PC?

Also what I'm trying to isolate now is whether it's because of my program or whether the game engine I'm using can't start in the first place.

If possible, install the library from the link below and run pyxeleditor to see if you get the same error.

pyxel: A retro game engine for Python - https://github.com/kitao/pyxel

sorry for the delay replying. I did install the pyxel library engine already (I retried just in case too ) as I thought it could be the issue. I also tried a few version of the libpng16-16.dll but it didn't seem to work either. 

In the latest version (ver.0.3), I changed the packaging method of the application significantly. I don't know if it works, but give it a try.

I still don't know what kind of PC it works on and what kind of PC it doesn't....

What type is your PC? (A kind of standard user PC, or a development PC?)

I'm sorry, according to information from others, 0.3 seems to give the same error.

And I just got some information from the user, so I started to verify it.

It may be helpful to provide information such as your Lovely Composer_ver.0.3 / log.txt file and OS environment.

Perhaps I fixed this error in ver.0.3.1, so please check if it works!
