Diamond Software

Diamond Software is an entertainment company introduced in WarioWare: D.I.Y.. The company publishes microgames, comics (under the name Diamond Publishing) and records (under the name Diamond Studios). Prior to WarioWare: D.I.Y., Mona, Jimmy T, Ashley, Orbulon and 9-Volt left WarioWare, Inc. to work for Diamond Software. In the D.I.Y. Forum feature, they talk about this: VROOM: Just heard a rumor that Jimmy T and Mona of Diamond Software used to work at WarioWare, Inc.!

blobmob: ''for real? why'd they leave? was there a big fight? lol''

D.I.Why: ''I heard Wario never did any work! I hear he's up to something now, though…''

Also according to the D.I.Y. Forum, Joe runs the company. Although not explicitly stated, Game & Wario implies the departed employees have returned to work for WarioWare Inc. at some point in time.

Diamond Software's microgame sets/records/comics have their own category in the D.I.Y. Shop portion of the game and encapsulate most of the premade content of WarioWare: D.I.Y. The character sets and comics are unlocked based on the in-game clock, while records are unlocked by completing achievements.
