What's left is a surprisingly decent unlicensed port of Metal Slug 1 for the Neo Geo, running on Game Boy Color hardware. And genuinely: it holds up. The graphics are solid for a GBC bootleg, working within the hardware's limitations more competently than most unlicensed titles manage. All the bosses are present, though easier than their arcade counterparts. Custom cartridge, plug and play. Compatible: GBC, GBA, GBA SP.
