Hi, I've had an old R4DS for many years and recently picked up my DS Lite again, and the card sometimes doesn't work, plus the company seems dead and I didn't find any new updates for the kernel, so I was looking into getting a new modern card. Now I see all these different R4 cards, and it's quite confusing.. are they all from different companies? So far I had my eyes on the RTS Lite, any tips on the actual meaningful differences between them? ps: ideally I'd like one that works on both the DS Lite and 3DS, and can play both DS and 3DS games (and support RTS) in case I do get a 3ds eventually. the descriptions on the websites selling these carts are not very specific about what they actually support.
