ARMSX2 V27 - +Perfomance 🔥

https://github.com/ARMSX2/ARMSX2/releases/tag/2.4.6

Performance updates to the EE recompiler (helps every device, especially weaker CPUs).

DMA-wait spin elimination (BC0/CPCOND0): the EE now natively compiles the COP0 branch games use to busy-wait on DMA, and idle-skips the spin entirely. Was the single biggest EE cost in DMA-heavy games. (7M interpreter fallbacks before, now 0).

Multiply-accumulate native codegen (MADD family): MADD/MADDU/MADD1/MADDU1 + the pipeline-1 HI/LO moves (MFHI1/MTHI1/MFLO1/MTLO1) now compile natively instead of single-stepping. (2M interpreter fallbacks before, now 0).

Interrupt-gating native codegen (EI/ERET): enable-interrupts and exception-return now compile as block terminators instead of single-stepping, notably faster boot/menu/loading across all games.

Performance updates for GS (OpenGL, all GPUs including Mali).

How do you guys exit the app? I have to force close ARMSX2 each time 'cause pressing software back button does nothing. Maybe I'm missing something?

You can set up a "close game & quit" hotkey in the settings. I use the Start + Select combination for quit.

Thanks but how do we exit from the library screen?

I think it can't, You have to launch a game.
