Tip: If you give a Muncher tile custom graphics, it will still act like a coin when a silver P-switch is active, whether it looks like a coin or not. So make sure to use ExAnimation if there's a silver P-switch in the area.
This is firebar from SMB1.
You can set the number of little fireballs as well as initial angle in the cfg file.
Note for advanced hackers:
This sprite uses the WRAM write registers (0x2180-0x2183) for OAM transfer. If you use these registers during an interrupt, there might be a crash. If you don't know what this means you probably don't have to worry about it.
