* refactor: from guest threads to EE scheduler * feat: bad wip mpeg fix for code veronica * feat: cheap copy from host feat: small perf o vsync tick * feat: added EE clock Hz fix: fix MPEG out of sync with new EE refactor * fix: fix lotr tests * fix: fix cri dtx loading fix: fix wrong mmi instruction translation fix: fix thread info params feat: added EE timers decoder and consumer feat: split SFI and IOP memory to prevent collision and overrides * feat: revert wrong changes * refactor: change GS architecture * feat: IOP emulator refactor: codegen to catch callbacks on mips code feat: added a lot of entries or IOP emulator * feat: analyzer resolve the complete constant-producing sequence with five-instruction backward scan stopped at LUI and therefore * feat: remove recompiled version of GetRomName refactor: split IOP emulator logic feat: added more HLE IOP modules feat: added ps2_path * eat: enhance ELF parser with improved callable entry detection and control flow analysis * feat: update memory hint handling and enhance entry point discovery logic * feat: add SET_GPR_ZE32 macro for zero-extending loads with unsigned semantics * refactor: Refactor PS2 IOP Host Adapter and Memory Management feat: Added PS2Vfs for virtual file system operations, including file opening, reading, writing, and path resolution. feat: Improve VIF1 data processing to handle GIF image packets more efficiently. * feat: added a lot of tests * fix: fix texture caching feat: wip multi version on dbcman * feat: remove LLE IOPs
