UMP
There was some intial confusion regarding the title of this project but Fenring's mod "YR 1.002" was eventually renamed to "YR: Frenzy".
The YR 1.002 UMP ("Unofficial 1.002 Mini Patch") was developed by Marshall for the purpose of fixing various bugs in Yuri's Revenge that still remained after the 1.001 patch.
Besides not being official, YR 1.002 is not a "true" patch.
It is a mini-mod that doesn't affect the gameplay as a "normal" mod would and is similar in scale to the ini fixes Westwood distributed with its patches. It fixes the obvious bugs that Westwood never fixed, adds support for features like the Terrain Expansion or the Assault Mode, and includes the vastly improved DeeVious AI.
Advantage: Fixes a lot of bugs while leaving the original game intact.
Disadvantage: As it is a mod, you cannot have "real" mods running while using the UMP in the same way that you can't have YR 1.001 running if you are using a mod that is based upon the 1.000 ini files.
That said, several modders who have read the thread(s) or heard of the UMP elsewhere have already adjusted their rules to include most, if not all, of the bug fixes provided by the UMP.
If you don't use "real" mods, the usage of the UMP is highly recommended (although like official patches, games are not compatible with earlier patches). If you do use mods, encourage your favourite modder to incorporate the UMP fixes. If you are a modder, incorporate the UMP fixes into your mod by downloading the UMP Developer's Pack from the UMP website.
