I've been blogging my progress on building a USB adapter for the Atari Jaguar controller: http://forums.atari....ing-with-atari/
Once finished I posted about it in the Jaguar Code & Dev Facebook group and got enough positive response about making a batch to set up a Kickstarter campaign. It'll run until March 1st and I'm only one more pledge away from reaching the break even point where it becomes worth it to order components.
For many of you who own full Jaguar setups it's a little redundant, but it's been very useful for enabling better play with emulators. It's also kind of fun to be able to just chuck a controller in my laptop bag and play while traveling.
