> 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...
I guess it is more lack of english skills from my side that makes this text so hard to understand...
Just look at other ROMs with SMD headers in a hex editor, copy the first 512 bytes (which are mainly zeros) and paste them into the beginning of the SMS ROM. Then change everything except the first four bytes to 0 and change the first two ones to the hexadecimal value of the formula I've provided ( [Cartsize in KByte] / 16 ) and the second two to 01.
You can download a converted example ROM here (uh, why didn't I think of that before...): Hang-On (UE) [!].zip.

P.S.
I have to reset my Megadrive with the reset switch before I can play those ROMs from disk. Try that with your Profighter also.
