Trying to create something new with old hardware:
This is a feature of my RE clone engine especially aimed at 16:9 lovers, which implements a wide screen resolution on the PSX. Stuff works exactly like on the recent remaster of REmake, where the game is still working in the background as 4:3 but displays at HD ready resolution without the aspect ratio going fatty. The backgrounds scroll as you move, following the character and making sure you always get a nice idea of what's on screen (here
you can find a video of the feature in motion). Shots were taken from a PSP set in Zoom mode.

Hope that also leads to more dense backgrounds.
