Let's say I want to insert images into a PSX ISO, but the images have data sizes that are too large (they have the same resolution, though). I can go through the process of rewriting the TOC and rebuilding the ISO, but I'd rather not.
Is there a way to lower the data size of an image while still having it look like what it is supposed to be?
One possible idea I crapped out is to intentionally degrade the quality of the image so it doesn't look as good as it used to be, but still kinda resembles what it is supposed to look like with a smaller data size.
How does one go about dealing with such a dilemma?
