Oh i see maybe this is the solution:
When you extract the game.RGSS3A a directory named extract is created this directory has a Data and Graphics folder ,these folders have first to overwrite any other directory in the game folder
for example the Extract directory
View attachment 1503249
these folders have to go first into the game directory to overwrite the Data and Graphics folders
View attachment 1503253
After that the only thing that you have to do is to overwrite the data folder with my machine translation
also delete the game.rgss3a so the game does not use the original files
i hope this can help you
