I'm new to the Gamecube modding community. I had a Gamecube as a kid and it was my favorite console. I recently purchased a DOL-001 Gamecube from eBay to relive my childhood and have a nostalgia trip. I'm so excited! Of course, though, I'm going to mod it, which is something I didn't do as a kid.
Forgive me ahead of time if this is a question or topic that has been discussed a thousand times on here.. I specifically googled the term "gcforever best homebrew setup" and words like that, and was unable to come across a thread that gave me the exact information I'm looking for. I'm basically just trying to figure out the best way to go about running homebrew on my Gamecube. I've read countless articles, watched tons of videos, and read some threads in here.. and to say that all the information is overwhelming would be an understatement.

I'm planning on going the hacked game save route, which is why I bought the copy of Agent Under Fire. I'm mostly confused about what I should buy to achieve this way of running homebrew. I understand that I'll need to put Swiss on a memory card.. can an SD Gecko be used for that? Does the SD card have to be 2GB or less or can it be a larger size? Can I save games onto that same Swiss card or do I need to have an additional memory card? Can that additional card be an SD Gecko or should it be an actual Gamecube card? Should I get an SD2SP2 for game saves instead? Will that work fine or even better than an SD Gecko? Do I only need one SD Gecko? Two?
Needless to say, I'm left more confused with all the information I've gathered than less. I just don't know what the absolute best route to take in 2023 is when it comes to this. The primary source of my information has come from a YouTuber by the name of AJ ONeal. If anyone can offer me any kind of advice or best products to buy, I'd greatly appreciate it; I'd like to start buying what I need so that way I can run hombrew on my Gamecube sooner rather than later. Thank you to everyone who takes the time to read this!
