From #openttdcoop wiki
Please note: Many savegames require a certain version of OpenTTD to run since OpenTTD is not fully backward-compatible. Most games were played with a OpenTTD Nightly Version. Get the nightly at http://www.openttd.org/nightly.php. Starting with Sandbox Game 8, #openttdcoop introduced a set of additonal GRFs.
Note: game 17 missing at the moment. should be added sometime soon. Template:Archive Sandbox
