The WiFi version allows these two things to work properly, and while it keeps the former version's battle features, these are not implemented for online play, likely because Stock Control would have caused potential griefing within matches (by the distant opponent always choosing the maximum amount of stocks). Replays are now functioning with the inclusion of Fracture's replay mod. However, Replays and online play do not work properly as a result of L and R button light-presses causing online desynchronization. The former has Stock Control and Input Assistance as new features, which allows newer players to use advanced techniques better and have a stock advantage over experienced ones. Project M has two different versions: Full Set and WiFi. As a result, running Project M outside of NTSC regions requires either homebrew as to allow the Wii to run an NTSC version of the game or an imported Wii.

Project M only supports NTSC versions of Brawl, and no PAL build was ever released. Despite the end of Project M's official development, it still has been able to maintain its tournament presence separate from Brawl, including the formation of its Backroom, the New PMBR, on July 21, 2016. By 2014, it began to develop its tournament scene, with the number of entrants for Apex 2014's PM singles event notably surpassing the number of competitors for Brawl.

Starting in 2013, Project M saw a rapid rise in its popularity as more characters became playable and the mod became more familiar at Smash tournaments. Project M has been commonly featured at several national tournaments, such as the Zenith series, The Big House series, and Apex 2014, and it remains the most popular gameplay mod of Brawl in tournament settings.

Development of the mod officially concluded on December 1st, 2015, with version 3.6 being the last official release of Project M. Project M's development team was partly descended from the original developers for Brawl+, later known as the PMDT, or Project M Dev Team (formerly the PMBR, or Project M Backroom), having members from over ten countries. Project M's primary change from Brawl is that the speed of gameplay has been generally increased and the character landing lag is shorter, alongside the restoration of many Melee mechanics and elements, such as the addition of Mewtwo and Roy after their absence in Brawl. Brawl designed to make the gameplay more closely resemble that of Super Smash Bros. Project M is a gameplay modification of Super Smash Bros.
