A Puerto Rico DS update has recently been released (2 AUG 06) and while I kinda liked the basic gameplay, it was confusing as hell at first.
Until I found the rules for the Puerto Rico board game itself online.
You can also download a nice MS Word document explaining the rules here.
This has to be one of the most complicated boardgame-to-DS ports I've seen to date.
For those of you who are DS homebrew-enabled and enjoy nice, long boardgames with lots of rules then this is for you.
For those wanting to check it out on a PC or Linux box, then go here.
A Mac OS X port is in the works.
I've contacted the coder to see if he can slap in some basic interface explanation in a README in the download archive, but no word back yet.
UPDATE: This just in from the developer:
He's working on a better gamepay guide and has plans to program in a tutorial but it's a time-consuming and complicated process to do so.Originally Posted by johanb123
In the meantime, play around with it and use the online rules and guides to get it all figured out.
