I also think he was lying BUT there may be some truth to this
. He said you were supposed to find a secret (a power up I think?) in Level 9. He couldn't replicate it.
The cart had a level select so I kept choosing and playing level 9 until something strange spawned
It looked like an orb or something and no it wasn't the spark enemy. It was unreachable since it spawned under the platform.
Just for illustration.
Maybe it was a graphics glitch. My memory might be deceiving me but it looked solid for a glitch. I don't have the cart or the famiclone anymore
