of course. the r4i gold card is much better than dstti card. the dstti is very old flashcard, it is out of production now, and there is no firmware update for a long time. but the r4i gold team release new firmware every month, which make r4i gold card much better.
r4i gold and r4i sdhc card are most popular in players. both of them can support 3ds, dsi and ds lite. but personally, I think the r4i gold card has better compatibility.
The R4i Gold 3DS card from r4ids.cn has all functions of r4i gold v2.0. It support Nintendo 3DS, DSi and DS, including the latest 3DS V2.1.0-4 console. If you want to get a good flashcard, I think the r4i gold is better than r4i gold v2.0.
It has anti-piracy protections that prevents a lot of flashcards from being used on it. There are many r4 XL card, which can support Nintendo DSi console. such as r4i gold card from r4ids.cn,r4i gold v2.0 from r4ids.com,r4i sdhc card,r4 XL,dstti and so on.
The r4i gold card is much better than r4i ultra card. The r4i gold is most popular in the world. it can work on Ninendo 3DS, DSi V1.4.4 and DS console. the r4i gold firmware keep on update to support latest 3DS system update. But the r4i ultra card is a very old console. it is now out of production. And as lack of firmware update, it can only work on Nintendo DSi V1.4.1 and DS lite console.
it seems R4i has better capabilities than acekard 2i but alot of R4i's are fake.
it depends, if you want to play DS/DSi games on your 3DS than R4i 3DS is your only choice but if you want to play DS/DSi games on your DSi then the R4i Gold. Both of them are vrey popular in Nintendo players. It is hard to say which is better, just as you like.
Typically R4i cards are only bought online - but I wouldn't buy an Ri gold card. It's a fake card (the original R4i is red in colour). Most flash cards are made in china, including the r4i gold card. you can buy the latest version - r4i gold 3ds card online. It usually cost 2 weeks to delivery to you. As before said, the r4i gold 3ds is not the best r4i card. Maybe, the r4i sdhc 3ds is better.
R4 gold is one r4 gold v2 is a better one
R4i 3ds card is just a flash card, the 8GB memory card is just an additional choice, that is, you have to pay extra money for the 8GB memory card. R4i 3ds gold has been in market for a long time and enjoy a very popular reputaion, while r4i gold plus comes out this year and lots of people never heard of it .
It doesn't work and you can't make it work either. You could maybe buy an Action Replay DSi (if it exists) but you can better buy an R4i, DSTTi or an AceKard2i.
For r4i gold from r4ids.cn, the latest firmware is wood r4 V1.46; for r4i gold V2.0 from r4ids.com, it is the AKAIO V1.8.6 kernel; for r4i-gold card from r4i-gold.com, the latest software is r4i V1.71b.. Now it is already wood r4i v1.51b.
You don't need to reformat the r4i gold card. You just need to format the MicroSD card, and reinstall the r4i gold kernel and games. Nothing about the r4i gold card.
