hi, sorry to clog the forum with another thread,
but i am trying to patch a game to run without the cd.
it's an older game, with cd-checks. i am usually very
good at patching cd-checks, but this one appears to have an
illegal TOC. it doesn't call the getdrivetype function, but that
is not the problem. one of the data files reports as being
around 1.5 gb on a 650mb cdrom. i need to analyse the
game a bit more, but it appears to be calling getfilesize
to check it, but is there any way to rip the real data off the
file, although it has the illegal toc?

also, i will continue analysing the game to see if i can patch
the size checks.

any help would be much appreciated

Howdy,

it could use FindFirstFileA / W, file size can be obtained from that

yes, it actually uses CreateFileA,FindFirstFileA,GetVolumeInformationA among others to verify the files.
i've bypassed the main checks, so the game works now without the CD, but it still pops up a few "no disk in drive" messages at startup, so clicking cancel will just let the game continue. what i think is happening is that the game is attempting to acces I: (my cd drive) in ntdll and windows is returning the error box.
anyway, here is some info on it : i've attached the patch list and some bits of code

And I hope you have first copied all files from the CD to the game folder, yes?
