Beta 18:

• 
  
• "Pause emulation when xyz" option remained forever stuck in pause mode if PPC CPU was active.
  
• PearPC PPC emulation removed.
  
• Freezer cartridge ROMs had disappeared from GUI.
  
• Freezer cartridges didn´t work.
  
• Force Direct3D mode if hardware RTG board + PPC enabled. DirectDraw has glitches. (Will also have glitches in non-PPC mode but there is no need to change it yet)
  
• CSPPC/BPPC interrupt controller IO address accesses were not thread safe, caused random lost or stuck interrupts.

qemu-uae.dll has not changed since b17.

Beta 17:

• Hard reset now forces reload of KS ROM if maprom is active, previously map rom mapped image was still in use after hard reset.
  
• Fixed some more Z3 autoconfig bugs introduced in recent betas autoconfig updates.
  
• Only add VirtualAlloc() MEM_TOP_DOWN flag when OS is XP. For some unknown reason with MEM_TOP_DOWN my system suddenly started giving less address space than without it..
  
• A1000 with full KS ROM configured (instead of A1000 boot strap ROM) didn´t boot since b9.
  
• Reset didn´t clear QEMU PPC JIT translation buffer, fixes mysterious hangs after reset.
  
• Added main thread sleep option slider to GUI, reduces CPU usage when M68K is stopped and only PPC is active.
  
• PPC CPU model can be manually configured using ppc_model= config entry. Can be any QEMU supported PPC CPU model name string. (Model strings are in qemu source file target-ppc/cpu-models.c)
  
• Automatically disable m68k JIT autoconfig hack if only PPC CPU is active when autoconfig starts after reset.
  
• Fixed WarpOS (possible PowerUP too) semi-random program hang caused by lost PPC interrupt(s).
  
• Allow m68k JIT direct with accelerator board if board is not Blizzard model (no Blizzard memory aliases) CyberStorm PPC + m68k JIT direct at least seems to work, no guarantees.

Important: QEMU PPC libraries are now loaded from pluginsqemu. Old location is not supported anymore. Move all qemu dependency libraries and qemu-uae.dll to new path.
