Works phenomenally and the few issues already acknowledged are both minor and understandable (the map page, for instance). One question I do have, however, is whether anyone had noticed the minimap acting up? After taking mipc210x7.gui and placing it into override (overriding the previous one used to fix the HUD placement for using widescreen) the HUD works plenty fine and scales up more or less perfectly...except the minimap, which doesn't change size, yet changes my map location and results in my minimap effectively being broken. The only thing that appears to cause the issue is mipc210x7.
Here is a short gallery showing what I mean (There are also small black bars next to the menu icons at the top right, which I'm not quite sure about either, although they're not noticable in that "after" screenshot). It's the Steam version, and the exe has been manually hex edited.
This works with the Steam version, assuming you're able to manually hex edit your executable. From this and other comments I'm going to assume you don't have the proper executable. Make sure to properly follow tutorials such as this and reading the README.pdf that came with this before saying it doesn't work.
