Re: {Request Font Verdana}
My experience suggests that Verdana is not a good font to use, besides which, 12point will be very large and cause considerable overlap (IMS).
However, I would not use Olly to make the change... not permanently anyway. Olly is very useful for finding out what information, stored where, is used for what purpose... but it only modifies an executable image in memory, not on disk (afaik).
Better to Hex the .exe, or use a disassembler.
We've had all sorts of problems with changing the font, but it depends greatly on how tied you are to a particular client .exe, or group of .exes.
If you can find one with courier, arial or tahoma already set, you can search for those strings in the exe, if not, you will have to find a way to set a breakpoint in Olly where the textout dll call is made, and see if you can't modify the call structure the game exe makes.
The original game.exe doesn't seem to make any specification as to font at all... but almost everything in Korean is done using the Gulim font group. Especially at small sizes, there is very little scope for stylization of type. (see how many font variations you can get with latain script at 3px x 4px. ;) )
So basically, there isn't enough information in your request to even say if this is possible... If you don't know how to use Olly... this isn't really the place to ask... check out Intels documentation on i586 instruction set, and Microsofts Win32 Platform Developer Kit, and DirectX APIs.
For a quicker fix than all that reading up (if you don't know it already) look around the RFT thread for an exe close to what you what than you can find the font with a hex editor.
If you get stuck closer, I will gladly help. (e.g. you have a specific exe in mind, but it's not picking up your changes as you'd expect)
Re: {Request Font Verdana}
Using the PTZ font actually works out well once configured correctly.

The above site has a few step-by-step tutorials written in Portuguese on changing the font, as well as downloadable exe's with the font changed already.
