hey nice script and demo but the actual save script doesnt work :(

[DerVVulfman]

The demo includes scripts for both this and the 'Unlimited Save Files' script. They do not work togeher, so this script has =begin and =end tags around it... making it disabled. The script will work if you remove those tags, and disable the Unlimited Saves script that is placed below it.

[sagam12]

thanks again, i will try that out, would of been good if you could use both save scripts together but i think im going with the prompt for overwrite script :)

[Designer]

I'm making a game in RPG Maker XP and I started looking for scripts. This script works but the prompt window stays on screen after confirming overwrite and doesn't disappear until I back out of the menu fully. Can someone fix the code so the prompt window disappears right after the player chooses "yes" to overwrite at the save screen?

[DerVVulfman]

I tested the demo I crafted, deleted every script from it to leave just the menu itself, and even tested the copy of the script in the first post in a blank script. What I see is that the whole screen does in fact disappear when you hit YES on the confirmation, thus erasing the confirmation window. And when you hit NO, the confirmation again disappears while you remain in the save screen.

But the script overwrites methods in the Scene_Save script... an issue that many default scripts have where the update methods were not broken into smaller bitesize chunks. If you are trying to combine it with 'another' script, I can see the issue. But that would be a request in Code Support board, including the name of the script of which you are attempting to combine.
