Ok this is what I want in a slot 2 cart if theres anything with this then please post it and make my life a little easier
1. Allow me to rip game saves off my carts that I own to let me play the backups on my R4
2. Let me use
this
3. Work ok with my R4
4. Act as RAM for the Opera Browser
5. Uses MicroSD
So is there any cart that does all that?
1. There are utilities that rip saves off of GBA carts. You don't need a slot2 device for this... besides, if you had a slot2 flash device, how would you get the save off of your original GBA cart since they use the same slot? The utils aren't perfect though, I haven't found one that could rip the saves off of my newer games (FFIV-VI) or my Fire Emblem games.
2. That patch is for the EZV 3in1 ... so you need the 3in1.
3. Most do.
4. EZV 3in1.
5. Lots of them do.. but I don't see it being necessary.
My personal pick is the 3in1. I sold my G6 Lite in favor of the 3in1 simply because I really hated the loading times of GBA games. Since I don't switch between different GBA games that often (I've already played most of the good ones), I just need to write it once to NOR and then I use the 3in1 as a normal GBA cart. Plus, you get slot1+slot2 functionality, which is great. RAM for Opera is a plus, though I haven't found myself using it very much. Rumble is also a sort of superfluous feature, but it's good to have if you really want to use it... I guess.
Also, you can use your R4 MicroSD card to store all the GBA games and write them to PSRAM (faster, but not permanent) or NOR (slower, but makes the 3in1 a "real" GBA cart). So really, it's just like having an M3, G6, etc., but better.
