- Clipping processing of VDP1 fixed.

- An error with the L R triggers of the analog controller was corrected. The error where you can't set the Slider input of your joystick should be corrected as well.

- on the BBS, it says this ("AI problems fixed") is a quick fix for getting Game no Tatsujin 2 and Xmen vs SF working."

Thanks for the translation, Borisz ;)

SSF Ver0.09 prototype R1
Interrupt processing of the SCU was updated.
CDDA processing was updated.

Save State data version was changed.

• Added DVDNTL/DVDNTH mirrors
• Added overflow interrupt

• Added function for displaying vdp1 textures for debugging
• Other bug fixes

The interrupt processing of 68000 was corrected.
The timing of the CD block was changed.
The DMA processing of SCU was corrected.
The dynamic recompile processing of SH2 was corrected.
The drawing weight processing of VDP1 was corrected.
The pattern specification mistake processing of the cycle of VDP2 wascorrected.
The memory access weight processing was corrected.
The sound generation processing was done only for another thread.
The drawing timing of VDP1 might shift and sprite flicker.
At that time, please set SH2 Instruction Numbers low. 

LFO processing of the SCSP was updated.
Dynamic Recompilation processing of the SCU DSP was implemented.
The Sleep command/instruction of the SH2 was updated.
Dynamic Recompilation processing of the SH2 was updated.

Since the SCU-DSP was greatly accelerable, the DSP Thread option was deleted.
Also, the synchronous processing of the main threads had to be removed... (not sure about this line)

Save State data version was updated.
Sound recording was enabled.
Key assignment is F9 for Sound Recording.

Since the sound recording is performed by a low piority conservation thread,
it may not work in case it lacks a surplus of machine power.
When recording sound, please do not enable Scanline Base Timing and the Always Running options.
Furthermore, sine resampling processing of PCM is due to be changed in the near future, sound quality may change delicately soon. 

• vdp1 drawing processing was improved
• vdp2 drawing processing was improved
• SCU DSP processing was improved
• Hooking up of the backup library was updated
• This update focuses on improving speed.
• Games which use the DSP have become quite faster.
• Especially the movies of Grandia became high speed.

• Interrupt processing of the SCSP was updated.
• SCU DMA processing was updated.
• SH2 dynamic recompilation processing was updated.
• Memory access processing was updated.
• Memory access wait processing was updated.
• It seems that the correct wait value was somehow misunderstood before.
• Bitmap processing of the VDP2 was updated.
• VDP2 cycle pattern specification (designation/assignment?) mistake processing was updated.
• The exclusive operation of the CD access LED was updated.
• Updated (fixed) the SlaveSH2 Idle Loop option, it was not functioning even when enabled.
• The X/Y/Z rotation and Slider 2 are now mappable on controllers.
• Savestate data version was changed.

Although the behavior of a few games have become strange, R6 must be closer to the system. I will find and correct problems in the near future.

Subcode Q processing of the CD Block was updated.
The battle progress explanation screen in Gungriffon and the demo screen of Gungriffon 2 have stopped skipping.
Window processing of the VDP2 was updated.
Memory Access Wait processing was updated.

Mission Stick, Multi-controller and Mahjong Panel inputs have been hooked up.
Key arrangement (for the Mahjong Panel):
A-N = A-N keys
Kan = Ctrl key
Pon = Alt key
Chi = Space key
Riichi/Reach = Shift key
Ron = Z key

An option for the (SCU) DSP to be processed in an exclusive thread has been added.
However, since synchronization with the SH2 will become difficult, software with high (cpu) load may fail to work.

CPU usage for dual and multi-core enviroments has been set up.
Exclusive threads processed by the CPUS:
for 2 cpus (Dual Core):
CPU0 - Main Thread
CPU1 - VDP2 Draw Thread

for 4 cpus (Quad Core)
CPU0 - Main Thread
CPU1 - VDP2 Draw Thread
CPU2 - VDP1 Draw Thread
CPU3 - DSP Thread

Save State data version was updated.
Savestates from previous versions cannot be used. Since it's becoming difficult to maintain compatibility...
From now on, if save state data is changed, (backwards) compatibility shall not be taken into consideration.

Although analog input has been hooked up, it has not been checked much.
Since I only have a XBOX360 controller... 

As the old codes were too mess, so i have to rewrote the whole project. Now the progress

 

of the new project has caught up with the old one. Games can also boot. The following snapshots show the current progress.
