Ok so I resently buyed an R4 from an untrusted site! I though that it was some guy reselling some old R4's so I went ahead and buyed it, it was a great deal only 19.99 and a 2 for 1 deal! Little did I know about the HUGE world of clones. When I got my "R4" it was very flimsy and the sticker was very badly placed on. I went to there website downloaded the firware wich at the time I believe it was 4.0.0 and then ran it. It worked great! 7/12 ds roms did not worl for some reason yet they worked on the other r4's I buyed (I buyed 3 from that site for my brothers). Later that week I wanted to play movies and I wanted more themes. The normal R4 themes DID NOT work and instead the only one that did work was an Akard theme I found after hunting for hours. I tryed formattinbg some movies to the R4's instruction with the DS format and it was unreadable! the R4 did not play it, I tryed MoonShell, that didnt even load on it! After about 3 months, my brother updated my 3DS to the newest version 5.0.0-11 and of corse the R4 didnt work I looked on there website and for about 3 more months it still didnt have an update for it! Almost all the other sdhc R4 websites had an update expect for mine! I heard that if you formate/reset your 3DS that it downgrades the version... is this true? Here is that scamy clone r4 website: http://www.r43ds.org/products/R4-3DS-Dual-Core.html#write_review. Hope this helps and befor you guys post make sure you read all of it! BTW I posted this on the nintendo forums not the smartest thing todo.. I was banned!
