Very nice. I love Guzzler, because when I was a kid, in the mid-80s, there was an arcade machine for this game at our outdoor cummunal swimming pool. There was a small room in this swimming pool, where you could buy food and drinks and there were always two arcade machines in the back corner of this room. For several years, these were the games "Guzzler" and "Xevious", and I played both there quite often, with some friends.
I have a question, since I have a Master-System but no MSX computer. The two systems are technically related, I read in the internet, wouldn't it be possible, to port your MSX version of "Guzzler" to the Master-System, or would you be able to do that? As far as I know, only certain things need to be adjusted, that a MSX game also works on the SMS and there can be found several MSX-to-SMS game-ports on the internet therefore. I just don't know how it works.
