In this paper, we propose a set of guidelines which can serve to conduct projects combining preservation and analytical tasks concerning a given platform, including its video games, especially at a regional level. As the capabilities of such local platforms influenced how video games were to be designed and developed, we consider that they must be documented and understood when studying regional video games history during eras when local platforms were more frequent. We illustrate our approach with an ongoing research project focused on the heritage of the Swiss computer Smaky (1978–1995) and the video games it welcomed.
