Hello Yoona,
I believe you are using either Neoncube or JikariCube.
Yes, that is the way you are sending the patchfiles.
That will mean:
this patch will patch your grf file (since you wrote it 1 GRF 2010-09-10.grf)
Sorry, my bad. it's correct - the way you write it. but, you forgot the thing about "patch number"
it should be like this:
PatchNumber<space>GRF.Number<space>PatchDestination<space>filename.ext
so, could be like this:
200 1 GRF 2010-09-10.grf
*the number in blue is set up-to-you. otherwise, if you set the last number is 20.000, then, the next patch must be larger than 20.000 (i.e: 20.001, etc)
Have a nice day!
