Thank you for your post and welcome to the forums!
Your phone cannot not have HD games for a simple reason, the screen resolution is too low for HD games. Nokia C5-03 has a maximum resolution of 360 x 640 pixels, when compared to the so called HD phones, they usually have the maximum of resolution 800 x 480 pixels. Also, calling a game "HD" when in reality it uses a lower resolution can be seen misleading.
Hope this answers your phone,
