No capability to take a screenshot on iphone.

Just curious if there is a reason why the screenshot capability was disabled on the iPhone? Does it not work or was there another reason?
I'm curious because I was loosely planning to take a screenshot of the current game when saving the game to show on the load saved game menu.

Bret, I am sure it wouldn't be too difficult to fix that code to work properly on the iPhone, assuming that glReadBuffer() / glReadPixels() is even supported by the iPhone hardware?

I don't think that's what Bret had in mind guys as he wants to use frame buffer as a texture to put with the saved game that his users create.Bret, I am sure it wouldn't be too difficult to fix that code to work properly on the iPhone, assuming that glReadBuffer() / glReadPixels() is even supported by the iPhone hardware?

glReadPixels() is definitely supported - check out the OpenGL ES guide on ADC for any issues with that.

lol amazing how many people reply before reading what my post. It still compiles after uncommenting that block so I guess I'll just have to test it and see if it actually works.

Seems to be mostly the same as the code in iTGB, except it's passing GL_RGBA as format to glReadPixels(). I guess the only change the existing code needs is a check for screen format (16 or 32-bit).
