You get the same functionality nonetheless.
Eh, I would more say "same." The putting the timebomb aside, the official kernel for the R4i-SDHC/R4iSDHC carts is just horrible. I own several of these carts (which I then proved were literally all just
the same cart...money well spent,) all of them had the same issues like ROM compatibility, RTS sometimes corrupted my SD card, RTS also requires games be a folder called "games," any other folder will cause the cart to crash before launching the game, and several other issues. These were all replicated across all of my carts and different microSD cards. The other issue is YSmenu is ugly and extremely basic, lacking features like RTS and multi-skin support. Then to top it all off, you can't use a homebrew to replace the kernel (and loading ROMs through ysmenu) like you could with DSTT.
I would heavily suggest people spend the extra money to get a quality cart like the R4i Gold Plus. No timebomb, better kernel, proper RTS, and no need for Ysmenu.
