Last summer Andreas St??ckel updated his Andorra Commons support set of libraries for his Andorra 2D game libraries. This last update fixed support issues related to the 64-bit CPU usage of the libraries. Not long before he had also updated the public description of the project for those looking for it.
As per the Source Forge description:
""Andorra Commons" is a set of pascal libraries which are used by the audio library "Audorra" and the 2D graphics engine "Andorra 2D". "Andorra Commons" features a flexible plugin system, a file container format, compressors, sys utilis and more."
You can take a look at these useful support libraries at www.sourceforge.com.
