@Gaëtan - first and most importantly, welcome to the community!
i would always recommend the pine store for purchases, but admittedly Amazon also has some good deals![Wink Wink](https://forum.pine64.org/images/smilies/wink.png)
As for beetle-psx, it's a retroarch core so explore the in-game menu a bit and there are some resolution settings, but the optimal resolution for these emulators is 720p and so we have set that as the max for retroarch.
