Installing "extras" to make 98 have some of the things from XP does not change the OS to XP. More than just a few *files* were changed between 98 and XP, so installing a few files won't give you the real compatibility that XP would offer. Sorry, but you have to either upgrade Windows or else use 6.35 from now on.
Sigh, what are the chances khalid will make like a final version for windows 98 that has no bugs, especially the ini bug, that annoys me a lot :<.
