Example : Super Mario All Stars & SMW : Super Mario Bros - SNES
Emulator used : Geiger's SNES9X Debugger ep9r8
This kind of code I have only tried on Mario games. You can also do it for items if the game has them.
Now the way I found it for this game was to put a breakpoint on read on the star's address. That address is 0x7E07AF. Before you put the breakpoint start the game and at the beginning get close to the goomba like in the attachment. Then turn on the breakpoint and press run.
If we change at 03DE9C F0 to 24 the goomba gets kill instead just like having the star. The code before this address 03DE8F checks to see if you are close to an enemy or powerup. I changed
03DE8F 60 to 24. When changing it to an nop it wasn't working right so use 0x24. This will kill enemies and get powerups from a distance. Also if you don't change F0 to 24 at 03DE9C and you change 60 to 24 at 03DE8F is Mario who dies when getting close to enemies.
