ok i have a tough decision to make my r4i recently broke and i want to get another one and i cant decide between the ievolution or the dstwo becasuse of the features. the ievolution has an onboard 8Mb of ram, can run in dsi-mode, (and only dsi-mode since my dsi got updated to 1.4.3 thanks to my sister) but its buggy, hasn't been updated in forever. the dstwo only runs in ds-mode but it has a built-in cpu and ram and i can watch movies without having to convert then for moonshell, gba & snes emulation and these are general descriptions if you want the full description read below The CycloDs ievolution features at the time of release include: (more will be added with Firmware updates) Cheat code support from Action Replay Data Base Extra 8 MB RAM onboard Upgradable Bootstrap so Nintendo can not block the cart Full support or micro SDHC cards up to 32 GB and microSD up to 2GB Supports Wii Connection for games Slow Motion for games Real Time Save and Restore as seen on the R4i RTS cards USB Reader / Writer + special firmware upgrade module in the package Download play support so you can share games over WiFi Multi Language Operating System and interface iEvolution will include 8 MB of on-board buffer memory for speeding up file access speeds, which is four times larger than what we had on the CycloDS Evolution which came with just 2 MB. DSi firmware updates from Nintendo will not be able to block iEVO, because the flash cards boot ROM is upgradable and cart comes with the upgrade module (the circular puck like adapter with a USB plug and a slot for DS cart). And lets not forget that the iEvolution comes with all of the other amazing features that CycloDS Evolution had, including the Enhanced in-game menu and other exclusive features.
