Make a Wish…

… and do everything to make it happen!

I may have already presented you SeeedStudio they are a chinese webstore, selling a lot of stuff made by electronic homebrewer for electronic homebrewer. You will find there a lot of prebuild card with microcontroller, components, kits, … and they have too some services like Fusion that allow you to make batch of PCB at the chinese cost (i.e. low), but with as much quality as possible for such a service!

So, why I made this post? Not to make free ad to SeeedStudio (even if I like them) but because they have another service: Wish that like the name seems to be, it’s here to make wish, and try to make them happen. I recently made a wish, one that could help me, but I think other people too, about some custom connector that a lot of people use(d) everyday, the one that was made by Game Console maker like Nintendo or Sony. Apart for the NES, there is currently no 3rd party sourceable connector for SNES, PS1/PS2  gamepads. (and lot of other one) The only current way is to take them from broken (or even working game console) or if you are lucky find an extension cord and cut it to get the femmal connector.

So if like me you need a reliable source of such component, please vote for my wish and spread the word around you!

Some WonderSwan Pr0n…

A friend of mine asked me for internal shot of the WonderWitch, so I do it even better, I take all the games I have with me, open them, then make some pron WonderSwan cardridge photos 😉

Here is a view of all the cartridge:

You can see that here the WonderGate is bit shy, he didn’t want to be nude on these photos 😉

Wonder Project!

 A few month ago, I was speaking with friend about the marvelous Bandai’s WonderSwan, about making something that is missing for now on the platform: Flash Carts.

But before going more on the subject, I will give you some clues on the WonderSwan, and why it can be so attractive, even if it didn’t went out of Japan.

The WonderSwan is the last video game console made by Bandai, and it was at first a project of Yokoi Gunpei just before his tragic death. This handled game console was in direct line with the Gunpei’s leitmotiv: “Lateral thinking of obsolete technologies”

All his life he try to make the cheapest possible device, without lowering the quality, and this by using “old” technology and by finding a new way to use them. The Wii Remote, is an example, but the GameBoy too, or even the Nintendo DS, they use “obsolete” technology in them, but with modern goal.

There is too much to say on this and could make a full article, but the WonderSwan was made with this idea. When you look at the specs of the CPU of first model, a NEC V30MZ (a clone of the 8086), and when you think that the first WonderSwan was out in Japan in 1999 this look a bit old. But this come at a big price: the device cost was awfully low compared to competition, it was sold at ¥6800 (~$60 / ~50€) when the GameBoy Color cost at least the double or the triple. The other major advantage of the WonderSwan was it’s autonomy: ~30-40Hr … with only ONE AA battery!

The first model was only black and white, like the original GameBoy, and two other version come later, the WonderSwan Color (2000) and the WonderSwan Cristal (2002) with for both a color screen (241 color out of 4096) more RAM (512KB) and for the later a better screen: a TFT LCD instead of a FSTN one used on previous models.

All of thoses models comme in multiple standard colors, and it is, maybe, the video game console with the most special edition I ever see.

So our main problem here is that the WonderSwan use, on each cartridge, a custom chip named Bandai2001 or Bandai2003 and some of its function are still unknown.
