So I dusted off my Snes recently, and all my old games seem to work! Huzzah!
But! Yoshi's Island seems to have a couple of glitches that weren't present the last time I played..
Sometimes when collecting coins, Yoshi will act like he hit his head on a harmless celeing and then fall out of the sky, or sometimes be pushed through the floor if the coin was level with the ground. (just the coins that are floating in the levels, not the ones produced from enemies being hit with yellow eggs)
There have been a couple of times when the sprites completely disappear from the screen. I am not sure what the cause of this is, but it can usually be fixed by backtracking in the level and then going back to the area where they disappeared.
Now for the big one: I started a new file, and am stuck in World 1-6. Every time I go into the secret tunnel with the Mole Tank transformation, I can move Tank Yoshi over to the edge of the dig-able dirt, and then one of three things happen..
- the game freezes, but the cave music still plays
- the game goes to a black screen, but the cave music still plays
- the game boots back to the title screen, as if the reset button has been hit
I checked that level in my other two files, and it happens in those two files too.
I've cleaned the connectors on both the pak and the system, so it can't be that. I guess YI is just suffering from old age (come to think of it, it was used when I bought it..)
