Giant Mario Bros

This hack will make Mario and Luigi huge, twice their size.

The levels remain basically the same, but some changes have been made to accommodate the resizing of the player.

The Nintendo Entertainment System (1983 in Japan, 1985 in the West) revived the North American video game industry after the 1983 crash and established conventions — cartridges, licensing seals, save systems — that shaped the industry for decades. NES collecting is one of the most established retro markets: common titles remain cheap, but a well-known handful of low-print-run games (many from smaller third-party publishers) are among the most expensive video games in existence.

Gamevaro tracks Giant Mario Bros for Nintendo Entertainment System 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 Giant Mario Bros 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 NES release dates back to 2021.

Only a handful of market sales have been tracked for Giant Mario Bros, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common Nintendo Entertainment System titles.

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.
