PS4 classic runs some games, but not all!?

Hellow everyone. After a few years of following tronics, ive become pretty decent at cleaning PS4’s (all models)

However ive recently gotten a console, ps4 classic. Wich didnt wanna boot any game (it would overheat and freeze). So i cleaned it up, fresh thermals etc etc.

Now it runs games like Fall guys and other simple titles. However when i try to run FF7 RMmemake or other high-end games, it just gives me an error that the app cant be loaded. Any clues? Should i perhaps replace ]something? Its my first time running into this issue.

Pre-thnx for all those who tryu to assist on this issue.

Greeting from holland!
