Is there a trainer (infinite lives) ROM for defender 2 or defender arcade ?

Recommended Posts

Not difficult to make one using Stella. By watching what happens with RAM when you die, you can see that the lives counter is stored in $82. Issuing the command trapwrite 82 lets you find where it's decreased.


Clicking on C6 82 then typing in EA EA will replace the dec ram_82 with a couple of NOP instructions, which don't do anything but waste time.


Lastly typing saverom will save the modified ROM. On my Mac it was saved to the desktop.

Alternatively, add cheatcode '8203'. This modifies RAM location $82 to always contain 3 lives. So you don't even need to save a separate ROM; the cheat will be activated automatically when you start the game.
