R4 Gold Works great. Use an everdrive for gba port and R4 for the DS. Seller on amazon preloads software and sometimes roms.

https://www.amazon.com/dp/B0831TYNNJ?psc=1&ref=ppx_yo2ov_dt_b_product_details This is what I got.. I just got this one since it was cheap and easy to use and set up when I don't understand how to do a lot of this. Some of the stuff you said was even a little confusing for me. I don't really understand what GBARunner2 is. Is it software I would put on the SD Card I have in my R4 Card?

Sorry for the late response, I don't use Reddit that often so only just saw your reply. I got a r4 SDHC gold pro, and it seems legit to me, the normal firmware works on it and everything. The SD card it came with was unfortunately busted, and I've seen a few others mention my exact issue with the exact same card since, but replacing it seems to be a suitable fix.
Here's the exact card I got! It's not one I'd recommend unless you buy another microSD with it, but it gets the job done now I sorted it out.
