These things are pushing 40 years old. Even if it was new still in box will cause issues. Metal will oxidize and capacitors can leak. The plastic will turn yellow and discolorize. Cleaning the contacts with alcohol is a good idea.

You can actually use the PAL Mega Drive 1 AC Adapter for the pc engine, no problem.

Preventive maintenance can be a good thing, but there are important things to consider.
1. Is it preventative. Is the cap you're gagging to replace actually ever going to go bad.
2. Do you risk doing more damage than good. For most people the answer is yes as soon as they pick up a screwdriver. It only gets worse once they get inside. If they don't rip up a pad or trace while desoldering they do it when tucking the radial capacitor they soldered to smt pads into some cranny. Popular "cap kit" mills actually sell kits like this because it's supposedly too difficult for the average faggot to solder certain caps. I can't think of a better reason said faggots shouldn't be picking up a screwdriver.

Hands down bad recappers. There are relatively few systems a bad cap will "ruin" it. It might not work correctly, or at all, but it's not ruined. Bad caps rarely rip up traces and burn holes in things. That's a lot more common with recaps, and exacerbated by the number of unnecessary caps replaced. This will only get much worse with time, because a shit job can take time to fail. A large radial cap may take a bit of shaking to rip SMT pads off a board. Same for balls of solder that break off and short something. The list goes on. All you have to do is look at picture of soldering people do here and on their home board of reddit so see this shit is rampant.

this is why modern solutions exist like liquid solder paste that only needs a heat gun.
is kinda dumb sticking to primitive solutions when most of those repairs can be done quite easy and more precise with modern tools (available on japan and several places more)

Great for many things but it's far too expensive for poorfags. When you've spent your last $100 on a broken console on ebay all you can afford is a small coil of the lowest quality garbage. Also, "a heat gun" is the "primitive solution". And advanced being can solder a TQFP304 in under 60 seconds with a heroin spoon. Also, you completely forgot the whole part where you have to desolder the caps before soldering new ones. Surely a trivial step that you just forgot about because you've done it so many times.

Honestly 9/what I expected. It's hard to tell from the picture whether some stuff is sloppy solder or reflections, but there's plenty of visible slop. Looks like you also removed most of the base plates, which are there specially to prevent big caps from flopping around and tearing up pads. It's not a disaster. It might work. But personally I wouldn't power it up without thoroughly checking it. Especially the nasty parts, like around where you melted that chip. Fingers crossed.
