any video mods for GBA Player and GCN?

[roguetrip]

I had bought GCN last year, also purchased some genuine S-Video Cables for it. Sometime after I had purchased a GBA Player for it, Metroid Fusion/Zero Mission and a few others, but games look a tad blurry (menus look fine of the player). I was wondering if there are any mods to improve the picture out? Also had picked up a EZ Flash 4 GBA Flash cart, games look the same. I know they look alot better on my NDSL. Maybe this is just normal even though the games are 32bit I thought it would be sharper.

TIA!!
