It is an evolution over Raccoon Gang’s original XBlock, with cleaner code and S3 storage compatibility. You can try it out today by running pip install openedx-scorm-xblock in your native Open edX installation. This XBlock also comes bundled by default in the most recent release of Tutor.
A quick question - what SCORM Player does this xblock use? (For example, the Appsembler’s xblock needs licensing a third party component from JCA Solutions.)
