The multi-cart has so many games on it, thats a giveaway. I believe neo-geo only comes in one-slot, two-slot, and four-slot. The more popular multicart has over 100 games, i think there a smaller one with like 40 or so games -- but still, way more than 4. so the game select will show too many titles.
There are a few considerations to take my no account when recording submissions for Neo Geo titles.
- The soft dip switch settings must be shown and verified as default settings
- The bios chip needs to be verified. If it's original, game on. If it's a UniBios, it's a custom replacement that has additional menus with options ranging from region select to cheat codes. If the cab uses a UniBios, showing the in game cheat menu shows that the player is not modifying the code.
- Multicarts are pretty solid but some have some odd settings. Example: the 111-in-1 cart defaults each game to difficulty level 8. Not ideal for WR runs.
