The EZ-Flash IV is the long awaited Nintendo DS cart from the EZ-Flash team, known for their quality products with excellent compatibility in the GBA arena. The EZ-Flash IV is very similar to the EZ-Flash III – except it sports a mini-SD card slot, rather than internal NAND flash memory. As such it requires no external linker device, just a mini-SD card, which of course means that your storage space is limited only by the size of your card.

  • 32Mbit SystemLoader
  • 8Mbit SRAM for saver

EZ-Flash IV GBAtemp Review

Excerpt: "While NDS compatibility is not perfect, software updates look sure to make this a viable contender in the compatibility stakes in the future. GBA support is one thing that is sure to have a lot of pulling power for the EZ4, and the inclusion of internal memory in the cart ensures that compatibility is top notch - apart from the lack of a real time clock for GBA games, which is a minor disappointment, but as it is in no way integral, the majority of customers are unlikely to notice its absence. As it stands though, the EZ4 has a little bit of catching up to do in the software department, mainly with respect to the NDS side of things, despite being a quality piece of hardware."
