Hacks

Copyright removal hack #1

Variant that removes the Sega logo and jingle from the introduction (but not the Sega screen itself, which means a now-pointless fade to white followed by a fade to black). The bottom half of the Sonic logo has been abruptly cut off to hide copyright details; everything else appears to be unchanged.

Modified title screen.

Copyright removal hack #2

The most common bootleg variant of Sonic the Hedgehog, which removes the Sega screen, supresses the first instance of "Sonic Team Presents" and chops off the Sega logo (and copyright details) from the title screen (and unlike the above, the rest of the ribbon is left in-tact). The net result is a few seconds of black screen before the game begins. Nothing else appears to have been changed.

There are at least two known variants of this hack with a small handful of byte differences in the ROM header. This has no effect on gameplay, so cannot be distinguished without viewing the contents of the ROM.

Modified title screen.

"40 lives" hack

A hack which gives Sonic 40 lives at the beginning of the game. The Sega logo has been removed, as has the first instance of "Sonic Team Presents" (though the version seen after the credits, and the credits themselves are unaltered). The title screen has also been abruptly chopped off to hide the Sega copyright details.

Modified title screen.
