How many versions of RBI Baseball are there?
I believe there are five versions of RBI… Tengen released two versions of RBI for the NES. The older version had the standard grey NES cartridge while the newer version had the hip, slender black cartridge. The black catridge is the unlicensed version of RBI while the grey cart is the licensed version. The reason for the two cartirdges is that, shortly after getting into the Nintendo business, Tengen decided that they were not going to license their games through Nintendo. As a result, all previously licensed versions were re-released as unlicensed titles. The Tengen vs. Nintendo battle is quite the soap opera, stemming from the Tetris court battles. It really doesn’t matter though, just know that both RBI carts are basically the same. For the Famicom, the Japanese version of the NES, there is a Japanese-language version with a completely different roster, titled Pro Yakyuu – Family Stadium. According to the GameFAQs database, the original Family Stadium was released on 12/10/1986. T
