potentially dead pointer 2x 14500

i may have killed the laser by reversing the battery orientation. It was originally bought from someone here over 10 years ago. I am looking to just "upgrade" it now. what will i need if i have host and want to change out the driver, the diode (maybe still good?), and what else? would something easy for me to retrofit? I don't really know how laser pointers work, but am eager to learn.

ok, i opened it and the driver appears burnt, and while messing with it, one of the wire fell off the driver. i guess i need a 16.8mm step down driver to 200mw cyan (curtesy of gemini guiding me)
