I have a question about the Ez Flash 3-in-1 slot 2 expansion card for my DS Lite. I have two slot-1 flashcards: an R4DS card (original model) as well as an R4iGold 3DS card for my DS Lite. I want to play GBA games on it and it seems like this Slot-2 expansion card is the cheapest and best option for me. A few questions about the card: -Is it compatible with one (or both) of the above slot-1 cards? -Is the game compatibility 100% for all GBA games? If not, are there any notable exceptions? -Are there any drawbacks to the Ez Flash expansion card? -Do I store the GBA roms on the slot-1 microSD card? (not on the EZ Flash itself) -Does it come with a battery for SRAM saves that might need replacing over time? Is there a simple way to save directly to the microSD card in the slot-1 flash card? -Are there any better (or cheaper) options for my DS Lite to play GBA games? I'm not interested in GBA emulators as I want the games to play natively in the DS hardware's GBA mode. Thanks for your help.
