How to Manually Save dat File?

[johnywhy]

How to manually save an existing dat file?
It's set to save on exit via cheat codes, but is there a way to save it without shutting down?
i searched Porteus docs, and could not find answer.

This what you're looking for?

Nope, saw that one. If it involves saving a file outside of my dat file, that's not it.

I want to manually trigger the same update to the dat file that gets saved on shutdown.

I thought I read something about a "dump" command, but maybe mistaken.

I understand and I think there is a way to do that I just don't remember what it is.

How big is your save.dat file?

[johnywhy]

How big is your save.dat file?

on my new 32-bit install, about 100 MB used of 500 MB.

I think this thread is what you want johnywhy. changes=EXIT: manual update

To keep track of my save.dat file I use a couple of scripts. You might find this one useful.

The check can be done when the save.dat is in use and when in AF mode.

The main problem with the use of a save.dat file is if changes exceed it's capacity, and that can happen expectedly, it totally screws up the file. And you don't find out until the next time you boot. I've had save.dats of 128 MB, 256 MB, 320 MB and 512 MB, currently at 320 MB again.
