Adding to this topic, I've been digging around all over the place to find a well compatible GBA flashcart that's still being sold. I'm
only planning to use it on GBA SP (and maybe a micro) so I narrowed down my options to the EZ-Flash IV Lite and NeoFlash 1Gbit.
The EZ-Flash IV seems the easiest in use (simply pop it in an SDreader and use the software right?) and with the largest storage, i'm just wondering how it works with savegames and realtimeclock.
*edit after reading around more*
Yeah nevermind, RTC isn't supported on anything you can buy nowadays. I'll also remember not to use micro->mini adapters I saw a few people talk about slowdown when using them.
I don't care about savestates or transplanting saves and all that hassle, just about playing the games with their own saves as intended but i'll find out about that later.
EZflash4 is the way to go i'd say, found instructions here

I think you can keep this post here. Might be an idea to make a sticky about the EZflash4 with that link since there seem to be a lot of people coming in and asking about using carts on their GBA. It was pretty unclear to me as well what goes on inside these carts when I read about NOR memory in general.
Putting it bluntly the loader kernel makes for the miniSD access and flashes any selected game(s) to the cart's NOR from where you can properly play the game if it's big?
