Your message brings back a lot of fond memories of those days of hacking games. We did something like what you described, modifying the OS and dumping the memory out. But we've gone one step further and installed a small hardware add on that basically consisted of a ram chip mapped to the same address as the hardware registers. Each time the program writes to the hardware registers would at the same time write to the ram chip. It was then simple to find out how a program sets up the interrupts and P/M and such.
