A demo of Bob's Game has been found on the developer's website.
Bob's Game was developed for the Nintendo DS by an independent developer, taking over 5 years to completely finish and has yet to be published.

The demo isn't working properly on several flashcarts (SuperCard DS One v3, R6 Gold, R4 DS, etc.; working on CycloDS). AKAIO has been updated to support this demo, grab the latest loaders. However, you may want to save time slappin' the ROM on your flashcart and give the demo a spin on an emulator.
