while it's tricky to find them legally for free, there are some options. The best place to start is archive.org, which hosts a ton of retro games, including some PC-98 titles. They're uploaded as abandonware, meaning they're no longer sold or supported by the original developers. Another great resource is fan translation sites like the ones for 'Touhou' or 'YU-NO,' where you can find patches for games that are already legally obtained. Just make sure to check the licensing terms before downloading anything.
For those who want to explore the classics, 'Dōkyūsei' and 'E.V.O.: Search for Eden' are often available on these platforms. Emulators like Anex86 or Neko Project II can run them, but you'll need the original ROMs, which can sometimes be found in legal gray areas. Always double-check the source to ensure it's not pirated material. If you're into indie games, itch.io occasionally has free PC-98-style visual novels created by modern developers, which are a fun way to experience the aesthetic without legal worries.
