PCSX2 Rev.831

wiiPCSX2 Rev.831 is released.PCSX2 is a PlayStation 2 (PS2) emulator for the Microsoft Windows and Linux operating systems. With the most recent versions, many PS2 games are playable (although speed limitations have made play-to-completion tests for many games impractical), and several games are claimed to have full functionality.

PCSX2 Rev.831 Changelog:
- Major overhaul of the savestate system! SHould now work better, be faster, have fewer problems, and use less hard disk space for the savestates
- The new PCR/TIMR code is now called correctly in recMFC0. This fixes Fatal Frame, maybe other recently introduced problems too
- Improved CDVD seek timing; should speed up some games that had abnormally long load times -- hopefully without breaking other games. (testing needed)
- Fixed a condition in the INTC hack that could cause it to hang in rare
occasions.
- Fixed a bug in the vtlb constprop support (stores weren't using the right macro)
- More work on fpu (thanks Nneeve)
- Emitter: encode negative 8 bit immediates for some instructions and EAX forms for MOV
- Implemented more correct support for the IOP's "isc bit" (bit 16 on the COP0 status register), which in turn allowed me to simpify some of the IOP's memory access and paging logic.
- Removed unnecessary rs flushes for loads and stores
- Save a few bytes on const flushing using 5 byte eax movs for 0 and -1 instead of 10 byte immediate movs.
- Usual code cleanups and optimizations

Luca Elia's WIP

The news of Luca Elia's WIP.

The developer said:
This version of Mahjong Vegas runs on royalmah.c hardware. But, unlike the previously dumped version, it does not use the internal ROM hidden in the TLCS-90 CPU, so it actually works in MAME..

.. after fixing the very, very broken routine that processes the interrupts in the CPU core, that is (my bad).

Haze’s Mame WIP Naomi

The news of Mame WIP Naomi

The developer said:

With all the recent GD-ROMs appearing I decided to take a look at Naomi.

It’s a complete system, and probably ranks as more powerful than anything currently emulated in MAME, so I’m not really expecting much.

The existing driver in MAME is mostly developed by Samuele Zannoli.

While most of the progress on it has gone very much under the radar for various reasons (probably overshadowed by the more advanced work in other emulators, and not really valued due to the knowledge that the framerates won’t be very good) it does actually do a few good things.

I recently fixed a few bugs, and now Capcom vs SNK actually gets past the character select screens, and ingame. It runs at about 20% speed on my 3Ghz C2D, and that’s without any real 3d emulation, but it’s pretty cool to see all the same (and you can actually ‘play’ if you don’t mind most of the graphics being blocks of nothing). Both this and Guilty Gear look like they could be potential ‘first base’ emulation targets for MAME’s Naomi emulation. I’ll see if I can get them there.

VisualBoyAdvance-M SVN r865

VisualBoyAdvance VisualBoyAdvance-M SVN r865 is released. VisualBoyAdvance-M(VBA-M) is a [Super] Game Boy [Color / Advance] emulator for Windows, Linux & Mac. Here you can get information about the latest development build of the Windows version and download it while you're at it.

VisualBoyAdvance-M SVN r865 changelog:
Important:
- Many games show emulation warnings in the log window (unaligned read, bad read/write address)
- Test: Metroid Fusion, Advance Wars 2
- Gfx.cpp/h optimization
- Test: Final Fantasy 4 airship intro
- Improve automatic 64k/128k flash save detection
- Pokemon Emerald hangs with white screen when no save state exists and wrong flash size is selected
- Remove 16 bit hack for filters
- Not compatible to software motion blur (display corruption)
- Add selection for compressed archives with more than one ROM in them
- Fix LCD colouring
- Game Bugs:
- Drymouth - screen flashes black after certain scanline
- World Reborn - 2 graphics bugs


Less important:
- Add GBA cheat editing support (GB already has)
- Look at Cheats.cpp (Core) and GBACheats.cpp (GUI)
- Add documentation for VBA-M (configuration guide)
- Improve AVI recording (produces asynchronous files)
- Enable audio stream compression for AVI files
- Add stereo upmixing support to OpenAL
- Verify BIOS files by checksum instead by file extension
- Merge HQ2x/LQ2x C code into code for HQ3x/4x
- Apply pixel filter to sprites and BG seperately for better image quality


Performance:
- Apply HQ3x/4x optimizations from C version to ASM version
- Apply pixel filter only to changed parts of the image
- Make even more use of multi-core CPUs
- Make use of 64 bit CPUs
- Have a look at the liboil optimization library

ClrMameProClrMamePro 3.125 is released.ClrMamePro is a so-called ROM-manager. With every new release of MAME a lot has been changed. New gamesets have been added, some have been removed, etc.

ClrMamePro 3.125 changelog:
- fixed: crash when doing a deep-chd scan on hashed metadata
- fixed: wrong rom statistic count for sets which only consists of nodump rom + chds + bios roms ;)
- fixed: old type chds aren't listed when wrongly placed
- fixed: "upgrade / downgrade" messages are wrong sometimes
- fixed: slow down when looking for missing chds
- fixed: crash when -r/-s/-h flag option is used an no warnings window is available
- fixed: some md5 over sha1 priority issue which impacts the wrong placed chd detection

QEMU v0.10.1

QEMU v0.10.1 is released. QEMU is a generic and open source machine emulator and virtualizer.When used as a machine emulator, QEMU can run OSes and programs made for one machine (e.g. an ARM board) on a different machine (e.g. your own PC). By using dynamic translation, it achieves very good performances.When used as a virtualizer, QEMU achieves near native performances by executing the guest code directly on the host CPU. A host driver called the QEMU accelerator (also known as KQEMU) is needed in this case. The virtualizer mode requires that both the host and guest machine use x86 compatible processors.

QEMU v0.10.1 changelog:
- virtio-net: allow masking of notifications on empty queue (Alex Williamson)
- e1000: fix rx descriptor low threshold logic (Alex Willaimson)
- x86 tcg: add NULL checks to lsl instruction (Jan Kiszka)
- kvm vga: fix screen corruption with -std-vga and Windows (Avi Kivity)
- kvm vga: fix screen corruption with Ubuntu installations (Glauber Costa)
- virtio-net: check right return size on sg list (Alex Williamson)
- Make qemu_announce_self handle holes (live migration after hotplug)
(Marcelo Tosatti)
- Revert r6804-r6808 (qcow2 allocation info). This series of changes added
a high cost to startup for large qcow2 images (Anthony Liguori)
- qemu-img: fix help message (Aurelien Jarno)
- Fix build for non-default installs of SDL (Anthony Liguori)
- Fix race condition in env->interrupt_request. When using TCG and a dynticks
host timer, this condition could cause TCG to get stuck in an infinite
loop (Aurelien Jarno)
- Fix reading encrypted hard disk passwords during early startup (Jan Kiszka)
- Fix encrypted disk reporting in 'info block' (Jan Kiszka)
- Fix console size with tiny displays (MusicPal) (Jan Kiszka)
- Improve error handling in bdrv_open2 (Jan Kiszka)
- Avoid leaking data in mux'ed character devices (Jan Kiszka)
- Fix initial character device reset (no banner in monitor) (Jan Kiszka)
- Fix cpuid KVM crash on i386 host (Lubomir Rintel)
- Fix SLES10sp2 installation by adding ISTAT1 register to LSI SCSI emulation
(Ryan Harper)
