A prototype of Super Mario World 2: Yoshi's Island, dated June 26th, 1995, and stored in the form of four 512KB ROM files, probably intended for a prototype EPROM cartridge. A working ROM is produced by combining the four files and fixing the header.

Notes

To fix header:

  • 0x7FBD => 0x05
  • 5 bytes starting at 0x7FD5 => 0x20 0x15 0x0B 0x00 0x00.
