Hack description

This is a hack which fixes the spike bug and also implements a near perfect rendition of the spin dash. There is an animation while doing the spin dash like in the later games. The only thing missing is the dust underneath.

Special thanks to Lightning & FraGag for their guides on how to implement this.

For some reason it doesn't like opening in a level editor, I don't know why. However, if you decompress the original Sonic 1 and decompress this ROM, you can open those decompressed original Sonic 1 files, then after you edit them, recompress them into the edit... I think.

The patch is in xdelta format due to copyrighted data being part of the original IPS patch.

Much Needed and Appreciated	PowerPanda	2020-07-19	Version 1.0
Going back to Sonic 1 after you've played Sonic 2 is painful. Once you've played with the spin dash, you can't go back. There are 2 spin dash hacks on this site, but the other one does not add the graphics. Go with this one. As a bonus, you'll get the spike bug fixed too. This was tested on Picodrive, Kega Fusion, and the Retroarch Core Genesis Plus GX. It worked perfectly on all of them, and is now loaded on my SNES Classic.

Very good hack	MathUser2929	2016-06-06	Version 1.0
While the Spindash lacks dust it is a minor issue and adds a big feature to it. That more than makes up for a small flaw. While the Spindash feature complete with dust has been worked into other hacks that have been released they were full on hacks that change so many features it's not the same game anymore. This hack scores points for it's simplicity. If you only want to add Spindash to the original game then this is your hack.
