While this is a nice small playground, it is closed source and hasn't been updated since 2015. Those who enjoy these emulated/simulated experiences in VisUAL's flavor may enjoy the "Cheap EMUlator: lightweight multi-architecture assembly playground" [0] it supports several variations of arm among other instruction sets(intel, mips, sparc) and to a much greater degree than VisUAL. It is also open source, regularly updated, and also provides a visual experience, though a bit more limited than Visual's. [0] https://github.com/hugsy/cemu https://github.com/hugsy/cemu
