DSiCade was developed by thewiirocks, with contributions from select community members (as described in the news posts).
The mirror available here uses the original source code which was graciously sent to me by TWR. ShoutBox, high scores and the accounts system no longer work (until I can either get the time or money to set them back up), but all of the rest should work exactly as it used to, even on a real DSi.
Big thanks to thewiirocks and all of the admins and users who used DSiCade over the years and made it such a big part of my teenage years. I don't think I'd be who I am today without the experiences I gained on this site.
If you want to put towards the server upkeep costs please donate to my Ko-Fi.
