So, I have experience in hacking and modding other game systems, like PSone, PS2, Dreamcast, and PSP. So you can explain things to me and not dumb it down. I've recently tried to get rid of all my Gameboy stuff, but since I just can't seem to get rid of it all. I got rid of one GBA, then I get a GBA SP from my cousin lol, I'm interested in buying a Flash Cart for it. And here's what I plan on using it for: -I want to be able to play almost any GBA game, without much hassle. Although I understand that GBA roms aren't necessarily like your common rom? -Gameboy Color, and Gameboy roms. I guess there's compatibility issues with this? -Gamecube connectivity. -Games that use the real time clock? I hear this is a problem? -Multiplayer -Either large capacity, or the option for some kind of flash card, like Micro/MiniSD. I ask all of this, because reading around on the internet is all mostly outdated, and I'm getting no where. This forum looks pretty active, so I hope nobody minds me asking. If anyone has any explanation of what I need to know, or a simple link to a flash cart that has all of these specifications would be great. Any info and recommendations would help me a lot.
