Reconversion project of Oblivion to Skyrim.
Installation instructions and links are not available, please wait for version 0.2
Type in game's console "cow tes4tamriel 5 10" to travel to Waterfront in Imperial City. "tmm 1" will show all map markers.
If you want to know more about conversion, read this thread.
If you wish to work with Skyblivion in Creation kit, you'll need a stripped Skyrim.esm master (because Skyblivion is bigger than Skyrim and CK can't load them both in memory at the same time). Use tesvsnip utility and remove CELL and WRLD groups from Skyrim.esm. Don't forget to restore the original one back when playing, or game will crash.
Welcome to Oblivion!

Beyond Skyrim huge map was split into smaller parts, so 64 cells limit is not an issue.
Skyblivion installation won't contain a single asset from Oblivion, everything will be ported from Oblivion by installer using binary diff patches, even master file. So Skyblivion will be perfectly legal and can even be hosted on nexus.
