Not all of us here at DS Fanboy own Macs (this blogger doesn't). Just remembering the times in grade school when everyone would huddle around the only computer in the classroom, watching as one lucky soul got to play Oregon Trail -- that in itself made us nostalgic enough for some classic Macintosh.
If you feel the same way, you might be interested to know that you can emulate a Macintosh Plus on your DS and relive the days of yore. Ah, how we loved yore. This is possible with Lazyone's Mini vMac DS homebrew (now DLDI compatible).
We haven't tried to install the application, since the process looks a little daunting. Some users are reporting success while others aren't, so you might want to keep that in mind before you decide to download.
