Konami GB Collection Vol.1

Konami GB Collection Vol. 1 is a compilation developed by TOSE and published by Konami for Game Boy and Game Boy Color.
Included on the cartridge:

Nemesis (titled Gradius on the GBC version)
Castlevania: The Adventure
World Circuit Series (Konami Racing on GBC)
Operation C (Probotector on GBC)

Curiously, World Circuit Series is called Konami Racing despite that not being the title of the game in any region (World Circuit Series in the US, F-1 Spirit in Japan, and The Spirit of F-1 in UK)
