# Apps : Ares \[ [site](https://ares-emu.net/) | [src](https://github.com/ares-emulator/ares/) \] > *"a cross-platform, open source, multi-system emulator, focusing on accuracy and preservation"* Ares is related to [bsnes](https://github.com/bsnes-emu/bsnes/) and [higan](https://github.com/higan-emu/higan/) ([shared ancestor](https://ares-emu.net/about)), but all three remain separate, active, open-source projects with different goals... or something. ## Files #### GBA ``` .gba game ROM .blu load undo (the state before last load action) .bsN where N = save slot .bsu save undo (the state that was just overwritten) .flash ??? .bsu & .blu disappear upon "Undo" ``` #### SNES ``` .smc game ROM .bsN .ram ``` ## Versions ``` Ubuntu 22.04 -> v126 Ubuntu 24.10 -> v134 latest -> v141 as of 2024-11-04 ``` There appears to have been a change between v126 and v134 that prevents previous GBA .bs* files from being loaded.
