Zerosquare (./4) :
The Neo-Geo is purely tile-based. On the Neo-Geo CD you could create tile graphics dynamically, but on the Neo Geo AES/MVS the graphics are fetched from a separate ROM in the cartridge (like the NES).

Then, how managed the creators of these games to port it to the SNES (Wolf and Doom) and Sega 32X (only Doom), which are using an exclusively tile graphics too?
