Paper Mario has many gliches.
1. There is no background on the window at the end of chapter scenes or beginning of chapter scenes even though most of the problems in them are fixed when you use wireframe rendering then swap back to normal rendering.
2. Textures are missing on the menus. The background for the menu you go into by pressing start ingame is incorrect because it is an old one if you use it in a building but doesn't show when you use it outside.
3. Lines show up on the 2d scenes on the left side in the introduction. It also happens in Donkey Kong text bubbles which seems to require too much cpu.
4. There's an odd problem in z buffering in shooting star summit, dry dry ruins, toad town on arch, dry dry outpost or battle scenes when you are talking to someone or moving across something. Objects, object parts and texture portions disapper and shadows clip through each other. Koppa Fortress and the second heart box on mount rugged have this as well but not when you are moving. The heart box one is not there when you move to the place on the walkway before exiting.
5. Is there supposed to be a motion blur effect in the game in battle and the balls from There are other missing or incorrect effects like the fading out effect on the logos, glow effect on balls and stars, missing mushroom transision to star in 4th cutscene, the candleflames, battle transision effect which is supposed to have a black background surrounding stars which shrink as they go off the screen, the flip effect which sometimes shows lines going through characters, and the background blackening effect when you get a new star or use a star power which has corrupt tiles in it.
6. You need to say that Paper Mario needs a good video card in Gamefaqs. My Intel graphic controller displays Ocarina of Time perfectly except for errors mentioned in gamefaqs and walls disappering when you get close to them does not show reflection mapping, fog, Bowser's flame in first battle, light and fog textures, magic spell effects, super blocks, fortune telling and some textures properly corrrectly due to not supporting pixel shaders, alpha comparisions( if your plugin uses them), and some of the blend modes used in it.
7. Collision detection is not correct. You can go through walls and other objects. Sometimes your partner goes through things instead of going around them.
