Maybe not a full-blown magazine, but definitely a web-based 'zine would be great .. one thing thats always irked me about this scene is the lack of cohesive information about news and exciting things .. well, certainly the "View New Content" button on these forums delivers a handfuls of granules daily, but if there were a more pro-active publication that really delivered interesting articles and news items around the edges of the scene, I think it could do well.
Another thing I think we as a community need is an effort to put together really well-packaged full-blown SD card images for 'plug and play' style gaming .. and I don't mean the grey-market ROMS and all that stuff, but legit apps that are meant to be spread far and wide. Plus if someone put together a list of free/PD/copy'able ROMs for each emulator, then we could have the situation where a big fat Emu disk could be made, containing everything properly set up and in order, and then just add ROMs to it as we find them. But imagine if there was a real group activity set up to build nice plug-'n-play SD card images for easy-to-use gaming ..
I know, this is what .PNDs are for, but I really look forward to a .PND-building group forming somewhere around the edges, making regular releases. This would be another good thing for a publication dedicated to the Pandora scene to support .. sorta like the way many PC mags in the UK go to the effort (or used to) of making CD's for the cover ..
