For programs in the Home folder (or subfolders beneath that) then the normal way to run them is via the VARS menu.

So from the HOME menu[1] press "MINES" then press "MB3..." (where ... is however much of the "MB3.hpprg" name it can display - not sure off the top of my head) and hopefully the tune will play.

Where RPL v Algebraic mode matters is that in RPL mode pressing the menu item will run the program immediately, taking its data from the stack. In Algebraic mode it will display the program name followed by open bracket and then it expects you to supply the parameters before running. For a music player program it's likely that it was meant to be run in RPL mode.

[1] To get to the HOME menu: press VAR, then press left+shift UPDIR two or three times until line 2 in the header shows {HOME} (assuming you have the normal two-line header display turned on).
