It's been an absolutely crazy week for Nintendo Switch Online with a string of leaks and rumours, and it doesn't seem to be slowing down. In the latest development, footage of unreleased NES games for Switch's paid subscription service have now surfaced via an online leak.

Below is a side-by-by video comparison of the current version and a "master version" build of the NES Online application (via Twitter user @orcastraw). As can be seen, there are all sorts of extra games included here such as Tetris, Pac-Man, multiple Mega Man games and other titles like Castlevania. There are also a number of additional 'SP' games on display.

The catch is that this is a build apparently dating back to October 2019, which means there's no guarantee Switch Online subscribers will necessarily be seeing these games made available on the NES application in the future.

Nintendo is currently focused on monthly N64 releases, but there's always a chance it could return its focus to other apps. In February, for example, it surprised fans with the EarthBound games on the NES and SNES services.

This latest Switch Online rumour follows on from news earlier this week about Game Boy, Game Boy Color and Game Boy Advance games possibly making their way to the service as well. A list of tested games has supposedly been revealed, and there are also claims Switch Online might be getting Transfer Pak support between the N64 and Game Boy services.

What do you think of the above games featured in this latest leak? Which ones would you like to see join the NES app? As always, leave a comment down below.
