It wasn’t all sunshine and rainbows. I remember losing hundreds of hours of progress on games due to memory card corruption. Or game cartridges/CDs no longer working, requiring you to buy a new copy. Or consoles getting straight-up bricked.
Hell, a ton of people have memories of blowing into N64/SNES cartridges to get them to work since they had notoriously unreliable connectors. But even though it was something that didn’t work great, everybody has fond memories of doing it since there wasn’t this amalgamation of voices from every direction telling you to be upset about it and clamoring for retribution. If something was broken, you got frustrated about it, complained to your friends, and then moved on with your life since there wasn’t anything else you could do.
Admittedly I’m not sure if it works for Japanese, but English has online tools you can use to print out a sheet to write out every character and scan to turn into a font file. Would be surprising if it didn’t exist for Japanese.
So ultimately you probably just need someone with neat handwriting.
