No, the amount of memory a MSX game needs should always be mentioned on the cover of the package. MSX standard only defines 8kB of RAM, IIRC, as a minimum. This is a free parameter of the manufacturer. Hence the obligation of the software makers to mention the amount of RAM the product needs. Grtjs, Manuel ((m)ICQ UIN 41947405) PS: MSX 4 EVER!
