I always wondered how they pulled this stuff off, and I appreciate the practical demo

Believe me or not you are my perfect RUclipsr great i do watch your videos with peace in my mind that i will learn something intersting
Keep it up bro

[@mustaffaleak9247]

You really do cover some fascinating stuff. Keep it up my friend. You deserve way more than 14K subs!
Love the use of ZX Spectrum's Target Renegade (it actually didn't use a gun, but we all know that 😜).
