About WonderSwan
Bandai's WonderSwan (1999) was a Japan-only handheld designed with input from Nintendo Game Boy creator Gunpei Yokoi's team, and it built a respectable library before being succeeded by the color version. Since it never released outside Japan, WonderSwan collecting is entirely an import hobby internationally, with complete, boxed copies especially prized by handheld collectors.
Gamevaro tracks Wonder Stadium '99 for WonderSwan with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding Wonder Stadium '99 to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This WS release dates back to 1999.

Complete-in-box (CIB) copies typically command a premium over loose cartridges/discs because the original box and manual are more fragile and get discarded or damaged over time — fewer complete sets survive.
