Development History

osu!droid under Pesets development

Note: Info is mostly taken from video as well as archived forum post on Wayback Machine

30 Mar 2010: A thread on osu! forum discuss the possibility of an osu! port on Android¹ but seem to went nowhere

05 Feb 2011: An early rhythm game, Beats, had a working prototype on an osu! Mod²³ which and later release under update 1.5b on 14 Feb 2011⁴

23 May 2011: Beats 1.6b released. Introduced support for .osu file format⁵ (up to v5 [citation needed]). Mark the first time osu map can be played on Android devices

14 July 2011: an osu! player under username Pesets begin working on a prototype of osu! on his Android tablet. After 5 days of work, on 19 July 2011, he posted his first technical demo of a dedicated osu! client on Android⁶⁷

23 July 2011: The project reached a state where it can be opened for public testing. Pesets made a separated thread and release the 0.3a version of the game⁸. General reaction being that the game can run well even on modest Android devices but still had a lot of bugs

Most of the 1.5.x release is only for fixing DDL and catch up with newer osu file format, which make 1.5 the last major update of the game

Somewhere before Nov 2016, the game was delisted from Play Store (most likely due to poor rating and no longer being maintained)

osu!droid under Neico development

29 Nov 2012, Neico made a thread about moving osu!droid to the OpenGL ES 2.0 backend instead of current OpenGL ES 1 (Pesets’ version), made a pre-alpha build that can’t play any map yet (but for some reason is available for downloading)²⁴

26 Sep 2013, Neico made another thread showing intention of allowing certain user to have access to the OpenGL ES 1 backend code of osu!droid²⁵, not sure what is the result of this

Note: It’s also known that osu!plus EX has been released before this post (as it was mentioned in the post)

It’s also unsure if Neico made contribution to any version of osu!droid under Pesets (especially 1.5.10)
