Im looking for BEEF DROP VE rom 2007 , someone have it ?

 

This is the most recent available ROM of Beef Drop released for public distribution. The difference between Beef Drop and Beef Drop VE is the former includes the POKEY chip in the cart, while VE does not.

 

The game code is the same; it checks to see for the presence of a POKEY chip, whether on the cart or otherwise (I.E. XM module). If no POKEY chip is found, it reverts to TIA.
