PlayStation Development Network

Sorry for the stupid question; I'm very new to PS1 development and I was wondering what the simplest possible way to draw a texture onto the screen would be.http://www.psxdev.net/forum/viewtopic.php?f=64&t=313 <- This example is the simplest one I've seen and even that's hundreds of lines long.

That is the simplest way of doing it. The only other way is if you code it up in assembly which would not include a lot of library functions, thus increasing your room in RAM. That however is a more complex route (give or take) unless you're super fluent in assembler.
