The Dreamcast homebrew scene never fails to surprise me. Not content with developing games and game ports for the system, we now have a piece of homebrew Dreamcast hardware on the way via those chaps over at dreamcast.es! Here's the translated article from DCemu:
"After turning several months, we've assembled an adapter to connect an SD card for the Dreamcast port of the link. The truth is that the speed is amazing and we already have a library to use. More info on our wiki.
But for the production of a few adapters and selling, we need to know how many people would be interested. Cost about 20 € with shipping to SPAIN (+10 € for some foreign countries) and sent with a CD with a program that will be able to exchange files with VMU BINS and launch from the SD card.
The prices have been changed to make them accessible to the world, remember that this is not done for profit but for the common good. For this reason we have reset the price originally agreed to cover costs of materials, and assembly time.
Later we will use the library and implemented quickly to a pager for the big games of AES4ALL, load / save snapshots DCaSTaway all emulators and ROMS can be loaded from the SD card.
Reason for development
The Dreamcast has support CD / GD, and visual memory card (VMU). The first one is read-only, and the latter has clear shortcomings: transmission speed and size. For this reason, are always looking for an alternative storage unit that saves the main support (save states) and other files, such as the configuration in our emulators. For a time it was speculated that the port expansion (G2) where the currently connected network adapter (or modem) is ideal for access via the new peripherals. But unfortunately, its architecture and requirements are far beyond our reach. Therefore, the serial port of an alternative that, while not enjoying all the privileges of the port allows for expansion if the most part, our wishes for a new carrier additional capacity and speed. This port allows us to use an SD card adapter that are usually used in mobile devices such as phones, MP3 players, etc..
* Good transfer rate in both reading and writing (about 500 KBytes / s).
* Very low average access time for reading (a few milliseconds).
* Support for cards up to 2 GBytes of SDS (not tested with larger cards).
* Loading binary from the card as a backup utility dcload and to / from VMU."
What an amazing development, I wouldn't of thought something like this was even possible! It even uses the extension port at the back of the console that was barely used! Imagine having all of your VMU save files in one place! I know in my case at least it would be major handy as I have around 15 VMU's worth of save files and it's hard keeping it all organized. Imagine being able to run emulators without having to keep burning CD-R's? This is one of the most exciting things to happen to the scene in a long time, and the fact there are going to sell it for rather cheap (cheaper than it'll cost to make) is highly commendable.
Chui is currently looking to see who's interested in one when they're ready, so if you'd like one of these reply at either the Dreamcast.es or DCemu forums. I know I'm putting myself for one!
