This would open the game up considerably, allowing to see way beyond the blue line.
So you would still get some scrolling near the net.
Theoretically this could display 2/3rds of the arena, as the full length of the live rendered game is about 3 full screens. I was thinking it may actually be possible to display NHL94 or any of them in 480i and also edit the resolution output of the rom to correlate. BUT the image is squished into 4/3 even though if displayed correctly would be sorta a 16/9 but vertically. This is demonstrated in sonic and knuckles for split screen.
Even though the system outputs 240p, it can also out put 480i. I've been working on various hardware mods on the genesis and have come across tons of info from various sites on the graphical output of the system and the games. Hey guys I have a mod request that if actually done, would be kinda mind blowing.
