Ah, didn't know they already had it lapse.
Pretty much perfect, the other games are more or less identical to their original releases. Nuts & Bolts is the only one with notable issues.
I guess Microsoft can work something out with the license holder in the future, as they do have a almost-complete version of a Goldeneye HD Remaster that was going to land on XBLA on the 360 before Nintendo said "NO!" to the whole thing (as they wanted the HD Remaster on the Wii back then, as they was going to just get a direct ROM of the the game). It would make for a great DLC game for Rare Replay next to Conker Live and Reloaded and a few GB/GBA/DS games .
Nuts & Bolts performance issues must stem from it being a latter 360 game and the most demanding of Rare's 360 Era games (it has the strongest visuals, was built for the ground-up for the 360, extensive usage of the Havok Physics engine, a ton going on in the hub town, ect), rather then shoddy emulation. As the 360 emulator gets better over time, so should Nuts & Bolts performance on the X1 but I could also see Rare trying to patch the game up too .
