Changes

*Transparency - Kirby Dreamland 3, Mecarobot Golf, Jurassic Park and any game that uses pseudo hi-res translucency won't display correctly in the default graphics engine. To get them to display properly in 1.51, you have to press 8 to switch to the old graphics engine. Or use an older version.

These are just a few problems, there are a few more listed [http://byuu.org/bsnes/accuracy here], and [https://zsnes.bountysource.com/development/bug_report here].
