[Request] Export file name Bug?

[tarky17]

environment

• OS: Windows10 Home 64bit Ver.21H1
• wiiuvcextractor.exe: Ver 2.0.1

I used wiiuvcextractor.exe to extract Pokemon Pinball Ruby & Sapphire.
Then the following error occurred.

Simple log

Guess

I guess as follows.

GBA Title: POKEPIN R / S
Writing to POKEPIN R / S.gba ...

This may be due to the / (backslash) between the R and the S.
The file cannot be output because it is a character that cannot be used in the Windows file name.
So it may be causing an Unhandled exception.

Suggestion of improvement method

If this guess is correct, for example, the unusable characters are automatically changed to _ (underscore).
Or maybe it can be solved by allowing the output file name to be specified in the parameter.
wiiuvcextractor.exe -n export-filename
