Cruise Chaser Blassty. It's kind of a Pokemon-esque game but with space battles. Sadly it's a little simplistic and my PC-98 emulator's character set is somehow a bit wonky so I can't read some fields sometimes, making it a bit painful to play. But if you like Pokemon and think an unlicensed Macross / Gundam / etc. ripoff mashup sounds cool, and you're better at setting up your PC98 emulator than I am, this could be right up your alley.
