From OHRRPGCE-Wiki

The system requirements for the OHRRPGCE are very low. It is neither hungry for memory nor hungry for processor cycles, nor demanding on your graphics card. It should run fine on even old crusty computers.

The OHRRPGCE is most extensively tested on Windows XP and Ubuntu Linux, but it is also known to work on the following operating systems:
