CycloDS Evolution from Team Cyclops is widely considered (and we would tend to agree) as the very best in Nintendo DS Flash Card technology. The CycloDS Evolution allows you to play from a MicroSD card games, movies, music, view images, read e-books and enjoy homebrew all from this one Slot-1 Device (slot-1 is the top slot on the DS and DS Lite).
The CycloDS Evolution is the first flash card to give Real Time Save (RTS) which allows you to save the game state at ANY point rather than having to wait for a save point in the game. (The M3 Team are the second to support RTS with their Sakura firmware for M3 DS Real and M3 DS Perfect Bundle) This means you dont have to close your DS and cross your fingers that the battery does not run flat! I'm sure most of us can attest to this happening in the past :)
Designed in Europe with quality in mind, Team Cyclops have designed a flash cart with longevity in mind. As the Cyclo DS does not have internal memory to store the firmware, there is almost zero chance of 'bricking' the card with bad flash writing. The operating system is stored on the MicroSD card that you insert into the Cyclo-DS.
Complete with a USB Reader, you can install the Operating System onto a MicroSD card without the need for any additional hardware (other than the MicroSD itself). Just slide the MicroSD or MicroSDHC into the USB Reader and insert into your PC! Copy your multimedia files over and firmware and then insert the MicroSD/MicroSDHC into the CycloDS.
The CycloDS also works with MicroSD and the newer MicroSDHC cards. This means you can run your CycloDS with 1GB, 2GB, 4GB, 6GB, 8GB and 16GB MicroSD and MicroSDHC cards. Much better than R4 and most mobile phones on the market :)
Two other great features of the CycloDS is 'soft reset' and the ablitity to install and change skins. Soft Reset allows you to get to the CycloDS main menu with the press of a combination of keys that will allow you to change the Turbo Speed, brightness and many other settings while still in-game and will not require you to reboot the console or exit from the game. Skin changing allows you to personalise your CycloDS and change the colours, look and feel of the flash card. Skinning is easy and there are 1000's of skins already available!
