Prompted by a customer request I have extended my QL-SD demo file with a few free QL games, 20 in total, including some that were never available for free before but for which I have the rights to release (basically the Jochen Merz catalog, thanks Jochen!).
I went to great length to try to make it as easy as possible, usually you can just select a game in the boot screen and it will run, everything is pre-configured. Even (Super)GoldCards are slowed down when necessary, still not every game will run properly on every QL configuration. The most compatible configuration is probably a QL with expanden memory but without any GoldCard.
