NJ updates his CPS2 emulator!

NJ updated his site with a new beta version of his CPS2 emulator for PSP! Here is the translation via google.

Modification point (beta)

The modification point is to be rather many, but the effect which it corresponds to hardship completely not seeing.
With the unreasonable [tsu] lever you abandoned the improvement of speed above this already.

romcnv.exe was renewed. Correction of trouble of the below-mentioned drawing as for the game which does
　Please do again to draw up cash file.

Correcting the trouble of drawing of the game below.
　Street fighter ZERO 2: Left and right of the victory mark of ranking indication is strange. (Correction being completed)
　[vuanpaiaseiba]: Part priority of opening demonstration is strange. (Correction being completed)
　Score of the top and bottom of ranking indication of the [maitei] pan is not processed the mask. (Correction being completed)
　[ezahoden] pre-world war 2 demonstration is not indicated in normally with D&D S.O.M. (Correction being completed)
　Part sprite of [pazurupu] 2 is not indicated. (Bug of ROM converter. Correction being completed)

In every game texture size modification to optimum value.
　But, because it was allotted at the value to which problem does not happen originally as for speed the change.

It tried not to read the PCM data when sound is made invalid.

It corresponds to the paddle input of [pazurupu] 2. (The same method as forgottn of CPS1PSP)

Modifying the calculation method of the pallet. Whether fading out and the like somewhat became good.

C68K substantially rewriting. (The M68000 core was drawn up anew, but bug correction and the like
　Because it is not in time, utilizing continuation C68K. Because speed does not change almost,
　This way whether it does,)

Z80 modification to CZ80 which customizes the core. CZ80 is to be lacking a little in accuracy, but
　Because it is not the strange sound driver different from NEOGEO, especially problem seems that does not occur.

There is no compatibility of the state data attendant upon above-mentioned and modification.
　It is the schedule which even in formal edition and is modified.

Is not bug, is, but the case where with the grapple game Raster Effects is turned to OFF the gap of the background part
　Cancellation. However, because drawing of the picture increases, (about average 1~2fps) speed falls somewhat.
　* Really, as for speed it is to improve delicately but you deducted with this correction and when such as zero whether.

Other things, detailed modification point large number.

Alittle hard to make sense out of.

b8a our trusty translator had posted a translated news post from NJ yesterday about his progress with getting it to work with the new eloader. Here is that translation.

I performed an operation check with eLoader 0.98.
I used a firmware 2.6/TA-082 PSP with the CPS2PSP that I'm building.
Hmmm, it doesn't run. I think maybe the TA-082 is what's wrong.
It displays the menu, and goes all the way to where you select the game, but freezes when trying to load the cache file. It looks like, memory that should have been allocated has not, in actuality, been allocated.
Of the 19MB that I was able to allocate, there was no problem up till around 11MB, so I think that applications that are smaller than that should have no problems.
Everything I've made has gone bad (laugh)

On the other hand, the GTA Loader version works properly. It seems as though the allocatable memory has increased by about 1MB. Hmm, I wonder if something can't be done about this.

I made some attempts to get it to work.
Please add the below text to ms0:/PSP/eloader/loader098.cfg
It's only for smaller games (as a rule of thumb, those with a zip file size under about 10MB), but I think they should run. It looks like the allocatable memory is exceedingly small.
You should also make the same change to NGEPSP and CPS1PSP as well.
Well, for the time being it looks like the applications I've built run better with the GTA loader, and not the TIFF loader. But, even better still is to downdate to FW1.5.

An example of how to modify loader098.cfg

b8a has informed me that NJ updated his site to say that this version is very buggy and ask that sites hosting the download to remove it while he fixes the problems.

This is great! PSP Emulation is unstoppable and makes the PSP the best homebrew device. Emulation is my favorite part of PSP homebrew.

Thank you NJ for you long-time dedication to the PSP and all of your generous contributions.
