Sounds like Robotnik Retro Crisis City edition.
Omg, it does sound like Crisis City. Close to the one from Generations. I hadn't played either 06 nor generations when I made this. xD Pretty neat to point that out, makes me want to combine the two now.
You really did it with old school instruments? Im quite amazed, it sounds like in the sega itself, but obviously its a remix! nice job, hope you do more like this! some songs sounds cool only in these kind of instruments!
Thanks alot >w< I plan on doing more, yes.
Please contact me if you would like to use this in a project. We can discuss the details.
