I made a 3D-printed case for Zwenergy’s WonderSwan headphone adapter. The STL files are free on my ko-fi.

Testing out my NES Boogie Boards on a MMC5 game cart, while talking about one of my favorite NES games.

In this post, I take a donor WonderSwan cartridge and install a flashable EEPROM, turning it into a reprogrammable game cart—albeit a bit cumbersome.

There’s not much documented on the English-speaking internet about the PC9821 Cx3. Fortunately, the PC98 discord community as a whole is incredibly helpful. Without them, I’d have no chance of getting my Cx3 working like it is now. Maybe I’d have DOS with a few games, but certainly not a full setup with a Windows…
