Improvement: only highlight saved state slots

[soundsnow]

All Load State Slots are the same color, I don't know which slots have been saved

For example
There're 4 files
Tetris (Japan) (En).s1
Tetris (Japan) (En).s2
Tetris (Japan) (En).s6
Tetris (Japan) (En).s9

Open Menu Screen
Load State
1->D-Pad Right->2->D-Pad Right->6->D-Pad Right->9

Skip Slots that can't be loaded

👍 This is something I've been meaning to do for a while now as well.
