[lolpbu]

fixed 000204.xyz having transparent background;
removed extra white pixel in the first "A" of 000000000000085.xyz;
changed the word "pontos" for "pontuação" in 00000000113.xyz and 000000000114.xyz;
added translations for NASU "ready", "start" and "game over" screens;

Those changes look good to me, though I'm gonna add here some changes that would also need to be done to the translation:

• The Kitchen Knife effect has a different spacing in the two versions of the FC menu
• The instructions item is named differently between the actual menu and the FC menus
• The pelo menu has a dot on the FC second pages of the instructions but lacks one on the non-FC variant, would be better to be consistent there
• The text in Map0001 was not centered; don't hesitate to copy and paste the line from Map0111 to fix this
• The Map0020.po and Picture/000000000000000000000000000050.xyz files can be removed since they contain the same line than their original version
