I’ve promised that a long time ago now and completely forgot to add the presentation here.
So, during the RGC2015, I made a presentation of the Project Madeleine, my primary project for the WonderSwan, which include the flash cart I’m working on.
The PDF of the presentation can be found here: Projet Madeleine Presentation
What’s that ? I #Wonder what it can be…? May be a #Swan? http://t.co/K1QNd88dBV
Ahoy WonderSwan users, developers and hackers!
The WonderMadeleine HDL code is available on the treasure island of GitHub. That’s some treasure chest you’ve got there.
(sorry for the pirate speak ;))
So yes the HDL code for WonderMadeleine is now available, to fit in the Altera EPM240T100C3 MAX II CPLD (a TQFP100 CPLD so not too big and easy to solder)
There is currently no support for external EEPROM, RTC of GPIO, but they will come shortly, I need to finish the documentation on how to access them from the IO port as current documentation is merely wrong. I’ll also publish a more correct hardware documentation at the same time.
This HDL code is currently licensed with the CC BY-ND-NC 4.0 license, that mean that
- You cannot take CPLDs, burn them and sell them
- But you can create your own cart and use the CPLD burn with the code, and you can sell the game cart you made using this CPLD (as you are not making profit from the CPLD, but from your game)
- I’m currently not fond in allowing fork of this project until it is fully finished, but I will be really happy for patch proposal for supporting another CPLD or correcting bugs
- And you can’t integrated this code in a larger project. that mean that you can’t integrate it with other HDL code in a bigger CPLD or FPGA.
Some of this limitation may change in a near future, but they are applicable at the time this line as been written.
I may provide in a near future a template board, either only the borders for a board that fit in existing cartridge, or even a basic board with the Bandai, Flash ROM, SRAM and save battery, depending on people’s need.
I hope that this project will help the WonderSwan homebrew scene grows as it deserve it. This game console is just an unknown jewel.
Ten years ago, two student from the Cornell University (North Australia) released the first public homebrew cart and software for the WonderSwan that does not use the WonderWitch. See here.
Their project was a major breakthrough as they where the first to document the WonderSwan hardware, and they are the original authors of the well known wstech document.
And after they made their release… nothing more. There were no concrete or public hardware development for the WonderSwan that went to a releasable product.

I’ve just finished the design of the WonderLyzer board, and I will send the PO for the pcb before the end of this week, so if you want one, your are running out of time, so be quick!

As I am working on my big WonderSwan project, I will quite soon make a PCB run for making analysing stuff more easy and clean, that why I will introduce a new accessory: the WonderLyzer.
