Good to know! In that case, I just uploaded a video of Sonic Spinball gameplay, and made sure to record the music loop at least twice on its own with no other sound effects at the beginning.
As far as my current Sonic LCD collection, then, that's all the resources I have to share right now. If you ever need any specific extra footage / playtesting / sound samples for any of these in the future, just let me know.
In the meantime, thanks for all your hard work on this super cool project. Happy I've been able to contribute in my own little way so far.
