an original model NES, but i'm sure it mostly was the fault of its common flaws regarding the 10NES chip and the ZIF connector, i was rather young at the time. today i own its toploader counterpart
an n64 because dumbass brother decided it'd be cute to gouge out the jumper pak just to see what it looks like out of the system, with a ballpoint pen, the pen broke and ink got all over the port, rendering the system useless
my brother's DS lite, because my brother syndromed over something and broke the touch screen, was $50 to replace with a secondhand original model DS
a game gear, because the sound borked and that GGs have shitty capacitors, again another common flaw with those systems
my second GG is suffering from shitty capacitors too as i can't go partway into a game without it crashing
and if computers are to be included, about 4 PCs and some word processor that had tetris on it, since i only ever played games on those before internet became a thing in the household
- for peripherals, a ROB and a superscope succumbed to the carelessness common with young children
- my brother cut the wires off an NES advantage
- 2 dreamcast controllers crapped out on me, an official and a third-party
- a third-party SNES controller stopped functioning right, i know it had turbo on it
- a third-party N64 controller i borrowed from someone that didn't work right
- both of my earliest gamecube controllers
- a genesis megafire controller dosen't work right
- a faulty sonic 1 cartridge i bought secondhand
- a sonic 3 cartridge i bought secondhand that dosen't save
- a gamecube action replay disc broke, and it was the earlier version that let you put in your own codes, expensive as fuck to replace now
- 2 iterations of GBA action replay cartridges that got bricked, those I used to get to deoxys in FR/LG/E
- a GB/C cheat cartridge that refused to work
- my first action replay DS, bricked
