Preload entire rom into memory - Styrixa - 06-03-2019

Hi All,

I'm new to the forum, and I searched, but couldn't find the answer. I apologize if this is covered somewhere obvious.

What exactly does "preload entire rom into memory" do? I know, in theory, what it is doing, but what effect would this have on performance and energy use? I often run emulators on my laptop, and I try to reduce battery use, and try to keep my computer cool. It is actually something I really appreciate about mGBA, as opposed to some other emulators.

I work on ROM hacking as a hobby, and am curious if enabling this feature has an adverse (or positive) effects on patched ROMs. I assume it wouldn't have any effect.

Generally, I assume this would improve performance if a computer has enough Ram, but I'm not exactly sure. I know a bit about how computers work, but I use hacking ROMs and Emulation as a way to educate myself, so please be gentle. Wink

I currently use a 2010 MacBook with 8 GB ram and 256 MB video ram. Right now, MGBA seems to work fine at tops speeds, even in fast-forward.

Any help would be greatly appreciated.

It's mostly only relevant if you have a hard drive and not an SSD. It's not a hugely relevant option for most users.
