Okay, I was messing around with the J2ME version of Sonic 1 by iFone and found some weird and unused stuff: File Names The file names for GHZ, MZ and SYZ STILL follow the original level order: the tile data is labelled ZONE1, ZONE3 and ZONE5. It's not even a direct port, so why keep the same order...? Unused Graphics These are from the later levels. This version only uses the first three levels. (I don't have the Part 2 version just yet) Platform from LZ Platform from SBZ In game text references the other zones; probably shared between Part 1 and 2 but still, you don't see these normally so I guess they count =P There's also the game over sprites, such as the ending with Eggman jumping on the End sign or juggling the emeralds saying Try Again. It's notoriously hard on my K800i due to the tiny buttons, so I'll attempt to complete SYZ3 again and see if said graphics are unused. IIRC it actually just goes back to the title screen, giving you a code for Part 2 so you can keep your score and life counter. I'll add this stuff to the wiki later, just thought it worth mentioning here first =P Oh and just as a sidenote, this came free with my phone alongside Puzzle Bobble and Metal Gear Acid Mobile.
