Topic: Disassembly of old MSDOS program

I'm trying to disassembly the VLC and the viewers of NuKe's journals in order to learn how the did so nice graphics effects in assembly.

I'm not a expert in reverse engineer so far, I did some search and found IDA Pro would be good to this task.
So it generated a asm code but, this result is reliable enought to be possible to assembly again?

Any one have some experience on this? Advices as welcome!
