Error when change the mednafen home base dir [message #5568] Thu, 21 June 2018 15:35 Go to next message

i changed the mednafen base directory from ~/.mednafen to ~/.mednafen12, but when i save the state of any game it's stored at the normal ~/.mednafen directory saves ..

so then i browse the code and set hardcoded the variable in main.cpp of the "drivers" directory and happened same problem...

also creates both directories..

so it's clear there's a bug here!

What do you mean by you changed the base directory? If you're modifying code to change Mednafen's behavior, and it's not doing what you want it to do, isn't that your bug?

seems that do you not know your own product, there's MEDNAFEN_HOME but either setting that variable or hardcoded, everything works until try to save a snapshot state on any slot, (0-9), it's create also a default directory (or segfault if not exits)

i mean in both cases:

CASE1: compiled or use a distribution (any distro) mednafen, set MEDNAFEN_HOME and then try to made save and not used the setting new directory

CASE2: i compile my own with hardcoded "~/.mednafen12" and happened the same problem

IMPORTANT NOTE: this does not happened with mednafen 0.9 codebase

I am unable to reproduce the issue you seem to be reporting.

During the test whose log follows, I saved a state, saved a movie, and saved a screen snapshot, and they all went to the expected directories:
