Sonic 1 – Score Rush is a modification of Sonic the Hedgehog.

This ROM hack introduces three new gamemodes to the game, all focused around one central gimmick, that being the Score Rush.

The Score Rush is a gameplay gimmick in which your score, which starts from 5000 points, constantly goes down at a steady pace. Should it go down to 0, the player immediately fails the challenge. Most standard methods of obtaining points still work, but you can also obtain points through rings, checkpoints, and powerups. Finishing levels awards you a fixed 1000 point bonus, with the score tallies being completely removed.

The gamemodes featured within this ROM hack are the following:

  • Score Rush: A full playthrough of Sonic 1 from start to finish, with the Score Rush gimmick. The objective is beating the game with the highest score possible. Running out of points leads to an immediate, full restart of the playthrough.
  • Endless Rush: A playthrough of randomly selected Sonic 1 levels, increasing in difficulty as it goes on. The objective is beating the highest possible amount of levels in one sitting.
  • Quick Rush: The gamemode allows the player to select one level of their liking, and playing said level under the usual Score Rush gimmick.

Other changes include:

  • A brand new main menu, from which all features of the game can be browsed;
  • The option to have a modernized moveset, including moves such as the Spin Dash, the Super Peel-Out, and the Drop Dash;
  • Leaderboards;
  • Complete, automatic SRAM support.

To play Sonic 1 – Score Rush, you must provide an original ROM of Sonic the Hedgehog (REV01). If you have bought the Sonic 1 ROM from Steam prior to its delisting, that should work just fine.

Its hacks like this that make old games breathe some fresh air. Bravo!
