If you’re not aware, the WonderSwan didn’t have a built-in headphone jack. Kind of like the Game Boy Advance SP, where using headphones required a special accessory. Unfortunately, headphone adapte…

Bandit Kings of Ancient China is one of my favorite games. It’s a strategy game, which makes it a bit of a weird fit for the NES. Originally released for the PC-88 and later ported to several other platforms, the fact that Koei brought it to the NES is one of the reasons I appreciate it so much. I’ve always been a fan of ambitious ports.

I'm sure you're aware of a GameShark, but what you might not know is how important the software is on each revision. The GameShark on the left is an earlier version, 2.1, made for the DMG and Pocket.

There's not much documented on the English-speaking internet about the PC9821 Cx3. I know of exactly three Cx3 owners in the PC98 Discord, and for one of them, English is a second language—so it can be tough to get info on these machines. If my Discord associates don’t have an answer, I’m pretty much out of luck. Fortunately, the PC98 community as a whole is incredibly helpful.

When I bought the PC Engine, it came with the Interface Unit, CD-ROM², and the v3.00 Super System Card. I won the bundle on Yahoo Auctions. Since it was sold as untested, I expected a drive issue and figured it would likely be the middle gear on the tracking motor—that part always breaks on these drives. The PC Engine system worked, but the CD-ROM² wouldn’t read any discs and kept making a constant clicking noise.
