We just finished uploading Bare Backstreet to the new launcher! If you didn't already, grab the launcher from https://launcher.amorousgame.com, start it, and pick Bare Backstreet from the game list. Disclaimer: This is a direct port of the old launcher version and released as-is. It works well, but is only available for Windows. Mac/Linux users reported having luck running it using Wine. Given Bare Backstreet is considered canceled by Team Amorous, the chances of it receiving additional support from this point forward are very slim.
