I have repaired plenty of PS5's and Xbox Series consoles - Liquid Metal is a manufacturing issue - you might be the lucky one that the metal just stays in place or where the metal spills out - PS5 mostly HDMI ports, some DOA or component failure
Xbox's also power failure and tons of corrosion...
Was for someone - not powering on and struggling to read discs. I've never worked on a Saturn before. The cartridge is a region switcher pretty cool little device
