Once upon a time, Sonicfan32 made this. People were wondering how the heck to actually implement them in the game, thinking the only way to do that was disassembly. Recently I revisited this sheet looking for inspiration, and my ADHD went "CHALLENGE ACCEPTED" despite already having enough projects on my plate. Thankfully it didn't take too long to do. This is the first ever graphics hack of Flicky for the Genesis/Mega Drive, called "Sonic in Flicky". It's pretty simple, it replaces Flicky with Sonic the Hedgehog, using Sonicfan32's sprite work. Amazingly it all conformed perfectly not just to the art style, but to the allotted tile space for the player graphics. Also, as per the suggestion from the comments on tSR, Tails makes a cameo appearance. I wasn't able to edit the credits text, as I couldn't find the pointers to relocate the text so I could expand it. However I did add a block of text at 0x4200 with credits. SPEAKING OF POINTERS, here's all the stuff I was able to map out while making this hack: Code (Text): 0x0051A: SEGA Logo (Nemesis compressed) 0x02372: Unused font (1bpp) 0x10106: Level tile archive pointer 0x101CA: "EXIT" archive pointer 0x10118: Sprite archive pointer 0x101B8: Sprite 2 archive pointer 0x11FBE: Title Logo archive pointer 0x120B8: Title text (ASCII) 0x1339C: Credits text (ASCII) 0x16E58: Level tiles (Nemesis compressed) 0x185FC: Font (1bpp) 0x18754: "EXIT" sign tiles (Nemesis compressed) 0x187D4: Sprites for most objects (Nemesis compressed) 0x1993E: Sprites for scoring, Iggy, and bonus woman (Nemesis compressed) 0x19EEE: Title Screen logo tiles (Nemesis compressed) Should also mention that the use of Nemesis compression is rather confusing. It's only a 128K ROM, yet most of it is empty space. From 0x0290A to 0x0FFFF is a massive block of unused data, which I put most of the edited graphics into and repointed into here. It could easily fit all of the graphics from the game, uncompressed, and still have space left over. Only thing I can think of is that this is a direct conversion of the 1984 original, and they used as much of the original game as-is, which meant smaller ROM chips for the graphics. Evidence for this was found in the graphics for the score display, as there's no 2P mode in the Genesis/MD version, yet the 2P graphics are still present... As for stage layouts, I didn't bother much with these. But I suspect they are uncompressed.
