Re: Any way to play *.sms files on a Doulble Pro Fighter?

OK, I know that the device supports the .SMD header. However, I just have began to play around with a hex editor and have only done simplistic things such as change the simple plain text found within the rom. So the information in the second part of your reply is a bit advanced for me. If you were to give a little more information on how to covert manually it would come in handy. Perhaps even if you had a .sms rom that was converted in this fassion it would save some time in determining if the Profighter is compatible or not. I did see that with a device added to the Profighter one could backup and play Master System games but I am thinking this would most likely be an attachement to the cart port and not to the inner workings of the unit itself leading me to think that it does have what it takes to play the games (SMS). But your information is most helpful and any further assistance is greatly needed. Thank you in advance.

Just to note, the particular rom I was tryimg to covert is 512k in size. I dont know if that helps...

Im using a first generation Genesis so it does have the hardware to play these games if I had the power base converter. But I want to use the games via a 1.44 disk through the DPF. Ay way to convert a .sms file to a .bin , .smd or .md file? > > It works okay for Magic Drives (I own one), but I doubt it'll work with Double Profighters since there is special hardware required, afaik.
