About your hack
The hack you uploaded, File:Sonic 2 losses in lost galaxy (OE)II (2017).zip, appears to have a few issues:
- There is no associated hack page. You need to create a page to show off the features of your ROM. For an example, see Sonic the Hedgehog Megamix.
- The ZIP file contains two hacks for seemingly no reason.
- The ZIP file also contains 15 screenshots, which have two major problems: They're in BMP format, and they're 640x480. Mega Drive screenshots should be 320x240 (or 320x224) and in PNG format. See Sonic Retro:Screenshots for more information.
- The file "sonic 2 losses in lost galaxy (OE)II.BIN" seems to have a broken Windows executable pasted to the end of it, along with build commands for an old version of VisualBoy Advance using an ancient compiler toolchain.
