Strange Cartridge

[Serbaside]

Can anyone identify the cartridge in the bottom left? It has the shape of a genesis cart but is gray with what looks like 2 windows.

Cart with the label torn off? Some sort of flash cart?

[Golpezas]

It's just a cleaning kit

That's a 'Player's Edge' cleaning cartridge. Mine has a copyright date of 1997.

Thanks for letting me know! Although I was hoping it was some prototype, darn

If you come across the Sonic 1 prototype, I read the Yuji Naka is still looking for it. ;)
