I host many of my developments in BitBucket (http://www.bitbucket.org). It's a free source code repository that supports many of the most common source control systems (Mercurial, GIT, etc...).
Until now, CPCDroid sources where private but I would like to give the opportunity to include new fixes, features or anything to anyone. So, to access the source code, please go to:
https://bitbucket.org/realfms/cpcdroid
If you successfully make any patches, let me know so that I can merge them to the main branch.
