Whn I play mario kart download play, it gets all slow and choppy. I am using a kingston(jp) 1gb micro sd and r4 v1.11. Is it my card, or does the original game do that too?
If you want a flashcart that's reliable with Download Play - you shouldn't have bought an R4.
the DS has 4MB of internal RAM, the Opera Browser requires more, hence the 8MB RAM Expansion Pack, I can't say I'm surprised, several systems have done this over the years including the Sega Saturn and the N64, I don't know of any handhelds that have done anything like it before though.(it must have internal memory for DL Play to work, yet you can't use the Opera Browser without a RAM packÂ)
