Hardware Others GBC Flashcart Recommendations?

[ChronoCrossfangirl2002]

Alright i feel like i've looked at this long enough and i can confidently say I literally have no idea what exactly to go with
to the point i see many places recommending joining some discord to get a custom cart flashed with game of choice and
proper RTC, which i feel is alot more out of the way than i can really express right now.

I'm mainly looking for something with RTC support and support for more "technically advanced" rom hacks like pokemon prism.

I use this cart from Inside Gadgets. It's out of stock right now, but they'll have more soon-ish.

Edit: You'll also need a way to flash it. Convienently they also make the GBxCart RW, which handles that.
