The DSvision is a flash cart similar to the R4 and M3 that allows people to copy files onto a SD card for use on the Nintendo DS. Earlier this year, the DSvision was launched in Japan and they have now announced that some of the Pokemon movies will be available for purchase for use on the DSvision.
The first Pocket Monsters movie will be available for download at the DSvision.jp site on August 20 for 500 yen. Four other Pocket Monsters movies will be available as special bundles. Movie 8 will be bundled with all the hardware required for the DSvision service for 4,280 yen. Movie 2, Movie 3, and Movie 4 will be sold as individual 512MB microSD cards for 2,980 yen each and will be available on September 11.
The prices seem quite high considering you can buy the DVD's for approximately the same price as these low quality DS videos.
