Game Boy Cartridge Capacity in 5-Pack Plastic Cases

There is no standard "5-pack plastic case" for Game Boy cartridges.

• Original retail: Individual clamshell (GB/GBC) or cardboard box (GBA).
• Aftermarket: Multi-slot cases exist (8, 12, 24, 48 slots) – generic "trading card" style or custom 3D prints.
• Nintendo never sold a 5-cartridge case.

If You Have a Specific Case

• Count the slots physically.
• Measure: GB cart = 58mm × 33mm × 15mm (W×H×D). GBA = 58×33×10mm.
• Common 3rd-party "5-game case" = 5 slots (marketing number).

Answer: Count the slots in *your* case. No universal standard.
