Well it depends on what you plan to install in it and run in it, does it? Regarding RAM, I have set 256 MB, which is overkill to make Windows 98 run smooth hardly ever touching the pagefile, and leaves an ample surplus for the old programs I have in there. And at the same time 256 MB is a small part of the RAM I have, an Internet browser can take that much, so I can give VPC that much too. And when you're running a virtual machine you're not supposed (?) to be running other resource intensive programs at the same time, so I can give VPC that much.

Even more so HD space depends on what you plan to install in it. Windows 98 SE takes less than 300 MB itself, the rest is what you'll need for your programs and stuff.

Note that you can choose to set up a fixed or a dynamic virtual disk, and the default option is the second one. It means that the virtual disk file will take in your real disk only as much space as it's actually occupied by files inside the virtual disk; the rest of free space reported inside the virtual machine will not be allocated in your real disk before it's going to be actually occupied.

So I recommend leaving this default dynamic option, and being generous with the maximum size. But don't go crazy, you won't probably want heavy files like pictures, audio or video in your virtual machine, if they can be in your real host instead. And the games you'll install in the virtual machine will be old and will take little space by today's standards, and many games for Windows 9x work on newer versions and you don't need VPC for them.

Depending on the number of game and programs that you're going to install, I don't think you need to think about more than 10 - 100 GB. But anyway since I think there's no downside to allocating too high a maximum size, because the file will actually take only as much space as it needs, you may want to make the maximum size higher for good measure.

(Dynamic virtual disk files do not shrink in size when you free space by deleting files inside the virtual machine; this is perhaps to prevent fragmentation from going wild. Actually if you want good performance I recommend you defragment the virtual disk file after its size has increased--after you have installed new stuff in the virtual machine.)
