My copy of Persona 4, which I didn't think would run at all because it's in worse shape than my copy of FFX, runs fine.
ps2 discs can work while in pretty poor shape. in your case it's probably just the type of disc. give the laser a clean and if your lucky you don't need to replace it while it will work fine
I have yet to run into the issue with my PS2 slim, but I don't play it often.
When my Game Gear ended up dead, I sent it away to be fixed by someone far more competent than me. They had to replace all the boards as the capacitors leaked, eating away the motherboard. Works like new now.
There has to be capable modders to fix our replace the parts to something as good if not better than the original piece. Probably won't be cheap, but there must be people out there.
Your Game Gear is another example of something that I've seen in more and more retro consoles, especially ones that utilized cheap caps. The Turbo Duo is another console that used low quality caps in their consoles. I had to rebuild about a dozen traces on one I restored a few years ago along with recapping the entire board. It was a pain, but in the end the console worked like new. Eventually all the caps in every retro console will need to be replaced since none of them last forever unfortunately.
the ones with shitty quality like game gear etc for sure. almost every game gear has shitty caps these days. and say og xbox in which most of them used trash caps
I could see it happening for the cd based sega consoles for sure. disc based sony ones aswell. it's really really uncommon though from what I've seen. it ain't gonna be anytime soon prior to ps3 era. ps3 xbox 360 era and later, ye those gonna die in the next 10 years if you don't replace stuff aside from the switch.
But I really can't see this happening for majority of card based systems that ain't named the jaguar. or stuff like the cube or wii. and or if it happens we ain't on this planet no more in other words gonna take a long ass time.
Snes N64, genesis, GBA gameboy classic, neo geo pocket I don't see it unless it's in a terrible abused shape. even less so for them cart based games that have some.
