I have a R4 sdhc ultra revolution for DS (NDSL/NDS)
None of the lastest game work ( like kingdom hearts , rune factory 3 , golden sun , pokemon black )
I did try many firware but only the r4 sdhc ultra 1.54 did not rezult in a black loading screem or did not say error file corrupt when I did...
I feel like school, back when I was actually in school, was more entertaining though, because of how much I get to interact with people, hang out with friends, and other stuff like that. All I get to talk to at work is my boring coworkers lol
