Super Mario Bros. Working Upside Down Pipes (POC Hack)

Proof of Concept hack made by ThroughT1m3. Click "show more" for a link.
From RHDN:
"This is a one world hack demonstrating the use of upside-down pipes, piranha plants in addition to upside-down pipe entry. Changed graphics and text. Use Floating IPS for patching."
And that's it. I liked this. At last the upside pipes are working as they should. If this wasn't implemented already in some hacks, then... Wow...

Sure, Upside-down pipes were already a thing in SMB2 Lost Levels, but were they working properly like in SMB3? I don't think so...
So this hack is pretty interesting. It can be used to make other hacks. I'm looking forward to those.
