I've finished my review of the CycloDS, a new GBA media adapter for the Nintendo DS and Nintendo DS lite using mijiSD and microSD cards.
The Cyclo team is a newcomer to the scene, with their only (released) product line being the CycloDS. So how well have they done? The CycloDS series is composed out of two (GBA slot) solutions. One made for the normal DS (and GBA) using miniSD and one specific for the Nintendo DS lite using microSD. Although they have been announced quite some time ago they have only recently become available. The Cyclo team have also announced another solution (no information released) and a Wii mod-chip.
