Almost all games should be compatible. you can order at 3ds-flashcard.com, nds-card.com, dgchips.com or another of the chinese shops.
3ds-flashcard seems to be down but I made an error in the url of dgchips: https://www.dgchips.com/ntrboot-flashkarten/8-r4i-gold-3ds-rts-plusbestes-r4i-gold-fuer-3dsdsi.html
3ds-flashcard.com is dead, they have the 3ds-flashcard.cc http://3ds-flashcard.cc/home/72-r4i-gold-3ds-plus-.html, also modchipsdirect and mod3dscard.com can be options, except for modchipdirect, 3dsflashcard and mod3dscard are accepting Paypal with a method.
I saw R4i on Newegg when I type R4i in search bar and enter and found there. They are shipped from First From Asia. I know it is come from China. It take about 2 - 4 weeks to arrive in USA/Canada/Mexico. Newegg do accept credit/debit card and Paypal. I recommend use PayPal if use 3rd party sellers on Newegg. If things are not sold by Newegg then use PayPal. If items are sold by Newegg then use credit/debit card. Amazon and eBay are not allow people to sell flashcarts due to strict law. If they do then will get banned accounts include with credit/debit card/PayPal then freeze to blacklist them. I don't know that Newegg is first time sell flashcarts. That's nice.
Those cards on screen are with Timebomb, unless you can find the R4i gold 3ds plus on it, don't order other ones, plus, I don't think the Newegg supports flashcard sales, just not be reported until now, but will be sooner or later. P.S: Some r4 cards' sites already do shipping from USA directly if you are not knowing.
I found this: https://www.newegg.ca/Product/Product.aspx?Item=9SIADDZ8KG2808, it's what I bought. It ships from Canada too, which is nice. I live in Canada.
Which site can support Visa for now, I planned to order another R4i gold plus and choose shipping from EU, however the Mod3dscard can't accept my Visa payment, I know they can do paypal too, but this time I want to use Visa card, do you know?
