Isn't there anyone who knows how to solve this problem???

Some games are really slow like crazy taxi and snow surfers, but if you make them speedloading it really makes a big difference. But these game were not selfbootable and were easy to remake (image with Cdrwin and then da.exe dummyadd burn it again and it was done). But now I have some games that I want to do that are selfbootable. I can't find how to do them. Cdrwin can not make an image. Please help? And one more thing, dummyad only makes images of maximum 80min but 90min would be even better. How can I do that? Thank you in advance!
