Body Wonderswan Color (WSC) Crystal Orange Operation confirmed. Inserted one AA battery and played the original "Jajamaru-kun" until clearing one stage. Initially, it wouldn't start for about 10 minutes after inserting the battery, likely due to being stored for a long time, but it started up without issue. The LCD's blackening is not noticeable, and the contrast dial works perfectly. Volume, Start button, and side buttons all function normally. Battery compartment tabs are not broken. Lock slide moves smoothly. Software Original "Jajamaru-kun" is included as a set, but please provide your own AA battery. The software also works well! Ken-J Wonder Swan Color Bandai
