A Link to the Past DX. Great romhack and the MSU-1 implementation is perhaps the best one of all of the SNES games that use it (some are bad).
All new, CD-quality soundtrack (MSU-1, higan/bsnes or SD2SNES only, requires separate download of soundtrack files)
Improved Pegasus boots, turn while running
Break pots with sword
Collect items with sword
Cancel flute transport
Death counter no longer increments when selecting “Save and Quit”
Use L/R to quickly switch between items
Slowdown reduced (FastROM)
There’s another romhack that builds on this one and adds a ton more visual enhancements and changes. I have not tried that one myself but it looks interesting.
