If you have yourself a download of Retro City Rampage DX, here's an important tip for you. Don't use the 'reset to defaults' option in one of the game's menus. It causes a glitch to crop up with no workaround other than deleting your save. Vblank Entertainment's Brian Provinciano has stated that he's already working on a fix that will be submitted to Nintendo tomorrow. Check out the blurb below for a detailed explanation of what happens with the glitch.

For clarification, what's happening is that the RESET TO DEFAULTS sets the video mode to 1:1 instead of zoomed 2:1. Sadly, this setting is changed in the save game and there's no way to set it back to the correct video mode. The save data will be fine once the update comes which simply switches it back to the correct video mode. However, as updates must go back through certification, it might be a little bit before it's live. In the meantime, the only solution is to delete the save games then exit the game completely to clear the setting. However, if players have a lot of progress and want to continue playing without losing it, they can always back up their current save game, and delete it on their system, then start a new game. Once the update goes live, they can copy their previous save back over and continue where they left off.

For the curious, players wanting see just how crazy small the sprites are in non-zoomed mode, they can hit the RESET TO DEFAULTS button, but they should back up their save first. And breaking news: I plan to continue updating the 3DS version even after this first update!
