It looks like there are two models of this. From reading some other posts here on the site, it looks like there is an older model with just a Gameport interface and a model that says "digitial" on it with a Gameport/USB adapter option. From what people are saying, neither model would work for pure DOS games, but this would be for my ITX LLama Win98 box. Any recommendations on either model? Any pros or cons to consider? Again, this would just be for Win98 or DOS games that run in Win98.
