So, I’ve been looking into the emulators on the stock A06 operating system and had the following findings. At this moment repositories have two available aarch64 emulators, both quite outdated: - RetroArch 1.9.3 - Mednafen 1.26.1 They basically run fine, but the main issue happens when trying to run SNES games on both: they both crash with `longjmp causes uninitialized stack frame` error. Of course, looking that both published aarch64 packages predate the DevTerm and A06 core, I compiled the [recent 1.29](https://mednafen.github.io/releases/) release, and it finally ran. It took almost 1.5 hours though. But I’ve found an yet another problem with it. I run DevTerm with 1.3x display scaling, because 1x scaling is too big and a lot of windows just don’t fit into standard 1280x480. However, 1.3x scaling causes issues with fullscreen scaling in both versions of Mednafen on any emulation core: ![IMG_7547](https://canada1.discourse-cdn.com/flex029/uploads/clockworkpi/original/2X/e/eeeaec5534414d411718ae9650252fae3da5e5e3.jpeg) Dropping the scaling to 1x fixes the issue and fullscreen works good, however the desktop becomes uncomfortable to use due to windows being too big. Any possible suggestions what I can use? I need a SNES emulator that I can use on DevTerm in fullscreen mode. I suppose I can try building latest Retroarch 1.10.2 because it will take care of issue there too, but it will also take _a lot_ of time…
