How to make a ps1 effect (pixel screen) or like a TV (stripes and errors)? Is it even possible to do this?
If I understand, you want to lower the resolution.
I made a game a few months ago in the ps1 style, I just lowered the screen resolution to 640x480 since that was the resolution of most games and TVs back then.
If by stripes you mean crt scan lines, you can probably find a gif or image somewhere and just overlay it over the screen with transparency applied to it.
Yes, use layer effects, to add pixelation and CRT effects.
