What is the cartridge for

If I remember right it has the stage sprites saved to it so it can stream them in instead of storing them in ram, leaving the system ram for more sprites, not disimilar to how the expanded ram carts ended up working but those weren't a thing yet.

As said above, it's a ROM cartridge containing game data. The Saturn's cartridge slot is much faster than the disc drive, so it can be loaded in very quickly as needed. KoF '95 predates the release of the Saturn RAM cartridge(s), so they had to use a bespoke solution specific to one game. There's also an Ultraman game that has its own ROM cartridge.

The Saturn is fully capable of running actual games from the cartridge slot, but it was considered too expensive and impractical to release full games on cartridge at that point, since the new hotness was having a bunch of CD audio and FMV in every release. Plus the Saturn's cartridge slot is notoriously sensitive and flaky, so it probably wouldn't have held up to regular switching.

So we moved from Resident Evil and now Saturn is the spam topic of the month?
