The fix seems good so far, but by applying it to save folders caused a trap: Now child's save folders move to bundle folder, hence saves will vanish, and the android/qt save tools are still pointing to old folders. Since the save part was only a compliance fix, instead of fiddle in master i'd rather revert this part now, then only touch this again if any bug show up. No worries. I'll be right here waiting.

This could be impacting other games around, but 4442 already quenched the spontaneous accumulation cases, by avoiding multiple event signals. MK8D is an atypical induced example. The reason was a controller applet accumulation, as we had no proper way to keep track and erase child applets on exit. Now we have. Enjoy your Plus button rushing fetish!

lizzie	9a30172e45	[dynarmic] Coalesce non-exclusive Write/Read fallback functions (#4158 ) the general idea is to have a common procedure form whom to call this way theres less "jumping around" for values of different sizes additionally this should allow for better codegen since most of the u8,u16,u32,u64 can be held within a u64 theoretically this means that you could deifne callbacks in suck a way that it's essentially as costly as a `mov r64, m64` but that's not doable due to the fact we have to do translations... Is this a good change? Primarily aimed for x86 and ARM to benefit, but I suppose LooooooongArch64 can benefit too.

After seeking that lead, it was found that the freeze was caused by a malformed HID history entry when the controller applet removed P2. Pressing P1 opens the controller applet, then Qt applet disconnects P2, which is expected. Upon seeking callstack and hid sync path, it was found out that NPad::WriteEmptyEntry: was using: ReadCurrentEntry().sampling_number + 1 instead of: ReadCurrentEntry().state.sampling_number + 1 (checked AtomicStorage in src\hid_core\resources\ring_lifo.h) Fixing that fixed the freeze, but killed the sound! Later handheld/docked was accidentally clicked and sound returned. Good lead. Then i just had to corner which part of the toggle was causing the refresh and do something similar at the controller applet return routine (PopOutData in library_applet_accessor.cpp). This part seems harmless, but i'm not clearly sure about how proper it is, since it was like a transplant and test operation. UPDATE: To try Diablo 3 on my machine it was needed to stub HID function 551. And to fix all abnormalies like multiple applet requests and crash the function PopOutData was reworked to ensurey idempotency among different applet focus conditions: focus state changed: updates state and signals if needed no state change, HLE application frontend: requests focus state changed notification already pending change message: flag remains true and no duplicate pushed to queue entry Reviewed-on: https://git.eden-emu.dev/eden-emu/eden/pulls/4442 Reviewed-by: MaranBr <maranbr@eden-emu.dev> Reviewed-by: lizzie <lizzie@eden-emu.dev>	2026-09-18 23:49:17 +02:00

In order to simplify things i've reverted all the rework, added a helper to identify whether a program has a parent Application and bounded it to it's proper stores. Although this is no big deal coz it doesn't have impact on emulation, it permeates to several routines, so it needs to be tested broadly.
