Certain sprites not rendering correctly

[djhworld]

This is most noticeable in games like Bubble Bobble -> the bubble that surrounds the character in the opening sequence is not a circle!

I've also seen something similar in Super Mario Land 2

I'm thinking this is probably due to the sprite horizontal/vertical flipping stuff

This is fixed in Super Mario Land 2, but still getting problems with Bubble Bobble....
