Translation of NJ's new page for his CPS2 emulator!

[BelmontSlayer]

The original page is here,

http://neocdz.hp.infoseek.co.jp/psp/cps2.html

Here's what I could translate from the page. (My Japanese is a little rusty) If this translation is used elsewhere please give credit to me (BelmontSlayer), as this took almost 45 minutes!

Japanese To English Tranlation

When I first made my CPS1 emulator, the emulation of the Musashi M68000 (The core of MAME) wasn't running so good. After figuring out how the core operated I was able to emulate the remodeling of C68K. Even more suprising was that sound worked quite well!

When i decided to try CPS2, the processing of sprites was actually easier than CPS1. Sprite proccessing is a big factor in emulation.

The PSP has 32MB of memory, but the OS takes 8MB by itself, so only 24MB memory can be used. Because 4MB is used for the emulator, you can only use 20MB as the data area for the ROM of the game. But, memory is not enough alone. If there is no XOR table for the encoding cancellation of ROM, its not very usefull.

I tried using sound with the emulator. As for BGM (Background Music) there is no problem, but because the SE (Sound Effects) cracks somewhat, it becomes a matter of concern. I tried lowering the volume, but it isn't solved that simply.

Also, there are several sprites displaying strangely. This is also a problem unless it is solved.

I tried using the same cache system as my NEOGEO emulator, and was able to move in-game. But, according to my expectations that's not good enough. Because the emulator is slowly reading the cache file, the game play very slow. The reason is that smooth animation when using sprite cache is not effective.

The CPS2 emulation is a small advancement. But throwing out the project halfway, without a regret is kind of hard.

My motivation is slowly declining. (NJ laughs)
I still haven't decided if I will release this or not.

End Of Tranlation

So hopefully he will release the source code...But it seems as if he thinks smooth emulation isn't possible.

-- Update --
A test build has been posted on the website. You can download it by following the link at the top of this news article.

Just a note, Make sure you run your rom zip though the included converter. Games will not run without the cache file.

[aries2k4]

Damn, hope he doesn´t give up. Lol, when NJ came out with the cps1 emu I was hoping it would give him ideas for a cps2 emu. Oh well if it can´t be done, at least NJ gave it a shot.
Thanks for trying NJ!!!

[wilbur]

interesting.

well, it's doesn't make it totally clear whether or not playable emulation is viable without sound, provided he fixes these display bugs.

As i suspected it's troublesome.


i'm not surprised he's getting hacked off with it all by now-surely he needs a holiday -bit worried how wired he must be by now.

maybe he'll take a break, have a go at another similar project and find/invissage something miraclulous and we'll all be happy again (for a while)

who knows

[ACID]

No NJ dont give up we all know you can do it.

[PSmonkey]

Anybody actualy notice there is a test build on that site?

[dagger89]

that wasn't there before...time for me to take a break from coding to have sum fun...

[kando]

very nice translation! my eyes are glued to this site for more updates :)

[Voltron]

NJ is great! I have come to really admire his work and I hope he continues.

[dagger89]

Can any1 translate?

Edit: I receive this error: This Game Doesn't Work. You Won't be able to make it work correctly. Don't bother. Press any button.

Marvel vs. Capcom: Clash of Super Heroes....

Thats great, so what works?

[ste]

Is the test build any good? There's a new CPS1 Beta 3 out too.

NJ is great....

[PSmonkey]

*holly Ship*

It freaking works great. I am playing 1944 right now. Sure it is not full speed and tends to dip alot, it still runs fantasticly for a test build.

Note.. Remember to conver your roms first for cache files first.

[dagger89]

Monkey: How do we know what games work and don't, bsides testing them?

I converted roms to cache, and put the roms in, but it still didnt work...

[ste]

Let the testing begin....

Alien vs Predator runs nicely. Full 60fps most of time but with just a slight laboured feel.

Keep to the smaller sized roms

[QueadlunnRau]

Note.. Remember to conver your roms first for cache files first.

How do you convert your roms to cache?

[dagger89]

With the converter in the same level as 1.0, 1.5... Just drop the .zip file in, and run it... Then when its done, transfer the cache file

[wilbur]

this is nutz, he's puttin it out man, i can't believe it.

[Apoklepz]

So, will Marvel Vs. Capcom work if you convert it?

[PSmonkey]

Monkey: How do we know what games work and don't, bsides testing them?

I converted roms to cache, and put the roms in, but it still didnt work...

You need to copy the cache file it generates (in the cache sub folder) to the cache folder on your memory stick.

It will end up being
cps2test/
cps2test/roms/ <- rom zips here.
cps2test/cache/ <- cache zips here

[ste]

Gigawing and Dungeons + Dragons:TOD are good (especially with sound off).

Big roms like Marvel vs Capcom should work but it could be very sluggish

[wilbur]

are you using mame roms or cps2 ones?

[dagger89]

CPS2 ones, I even clicked the CPS2 roms download section on the site...

[QueadlunnRau]

Xmen Vs Street fighter works!!! kinda choppy but playable!!!

[jaydee73]

Games tested:

Alien Vs Predator 55-60fps
Battle Circuit 50-60fps
Dungeons & Dragons Tower of Doom 60fps
Eco Fighters 60fps

X-men: Children of the Atom 30-40fps

[cazmiester]

**** this is his idea of a test build almost perfect emulation yes some sprite trouble and scratchy sound but otherwise perfect nj you are the hombrew coder of the year by far vote nj:) :) :) :) :) :)

[dagger89]

So, will Marvel Vs. Capcom work if you convert it?

nope... i rly wanted to ply it too... i have the ps2 one, and love it

[Apoklepz]

You mean Marvel Vs. Capcom 2?
I still don't know why with the bigger roster and all, I've never liked that game more than I like the original...Other than it has Cable and Jill in it.

You could still emulate it on your PC with the appropriate system bios and a graphics card...although it's gonna suck if you don't own a PC controller....Keyboards? Anyone?:D

[Vega]

How hard is it to "convert" the files (as explained on the first post) . Do i have to do much work?

well u can use ur psp as a computer controller now i believe...anyways gunna check this test build out right now, thanx NJ :D

[QueadlunnRau]

Marvel Vs. Capcom works!!! you need to use the "MVSCU" (US Version).

Marvel Vs Street Fighter -25-35fps

[ebitiba]

Puzzle Fighter 2 Turbo works perfectly except that the sound is a little weak and the game is not full screen. GREAT EMULATOR!

[ACID]

by the way great job belmontslayer for the translation

[ACID]

Oh so it does work.
yes it works and he has gotten a lot of games to work also for it.:)

[Vega]

do i make a rom folder and a cache folder inside the cps2psp folder? sorry for soundin like a noob but im abit confussled (again)

[QueadlunnRau]

Oh so it does work....cheers!

Naw your right the "mvsc.zip" European version does not work by itself.

You also need the "mvscu.zip" US version with it. :D

[Apoklepz]

Oh...I see.

[QueadlunnRau]

do i make a rom folder and a cache folder inside the cps2psp folder? sorry for soundin like a noob but im abit confussled (again)

The first time you run the test emulator it will created the folder stucture for you.

[Vega]

erm... help... where do i put the zipped roms and the cache file PLEASE!!!

[TrowaX]

@Vega Copy the cache file into psp/games/cps2psp/cache folder then put the rom in the rom folder and you are done.

[QueadlunnRau]

erm... help... where do i put the zipped roms and the cache file PLEASE!!!

Run the emulator once, it will create the folders needed, or just create the folders, roms and cache

[TrowaX]

OMG first release and they are running at like 30-45 fps and some running at 60 what more can i say lol you are a coder master man Thanks you !!!! NJ !!!!!

[pkmaximum]

WOW this emulator is amazing, the only bad thing is on some games, it seems like a lot of frames are skipping, but idk why he would even think of not releaseing this emulator its great =O

[Vega]

thanks... got it sorted. Gonna test Super street Fighter 2 turbo.

[QueadlunnRau]

Post your game results, fps and settings here and I will update my earlier list with your name on it.

I would be testing more, except I am at work right now =( I will be doing massive tests when I get home tonight tho.

OMG this is the happiest day in my LIFE! SERIOUSLY CPS2 on the go!!!! OMG ... be still my heart!!!

[QueadlunnRau]

yes it works and he has gotten a lot of games to work also for it.:)

Oops wasn't very clear on my list Sorry. That's just a "list" of CPS2 games so that people would know which games to test.

I have not tested all those games yet, just posted up a quick list so people did not have to hunt for which games were CPS2.

[Vega]

if you turn the Raster effects off on X-Men: COTA the game plays slightly better. If this is just a test version then Im shiting myself anticipating the official release (if there will be one). But f*ck me, this emulator is great for a test. Keep it up young esquire.

[dagger89]

Yea, I still have my ps2 so i play it sometimes, but I'll prolly start playing it on my laptop soon, since PCSX2 is working fairly well for Kingdom Hearts (DVD)

[delt31]

Super street fighter not only works, it plays 60fps on some stages!!! ken's was getting 60fps - guiles was around 45. This is SO amazing.

Alien vs predator is awesome too. NJ is truly impressive!

[Vega]

wtf? i just tried to run Super Street Fighter 2 Turbo and got a message saying "the game wont run... dont even bother" .

[delt31]

On a side note - does everyone's Street fighter Hyper on CPS1 play really fast?? says 60fps but it flies!!!! anything i can do to slow it down?

[Psphreak]

@delta, what you can try is going into the settings of the game and set autoframeskip to off and test it with Frameskip of 1 or 2. It may look a little choppy but it'll be a little more constant gameplay.

Nice work NJ, very impressed with this test version. Keep it going as I know we won't be disapointed.

here's the thing. The game plays very smooth with autoframe off and 0 FS. Now i want to slow it down b/c it just plays like it's in super turbo mode. If i increase the Frameskip, won't that make it faster? Or was this arcarde game (SF2 hyper) this fast and I'm forgetting something ? I just got the xbox 360 version and it's def slower

[SpacemanSpiff]

Rockman 2 works great - 60 fps with 22 khz sound

[Vega]

my dump of super street fighter 2 turbo comes up red and says it wont work. can someone help me out?

[TrowaX]

Doing what I mentioned does slow it down somewhat but the sound ends up syncing slowly :(.

[delt31]

ok so yours is lightning fast too? It's much faster than championship edition (which seems to be on the slow side ; )

anyone else having this issue

this cps2 emu is awesome btw - back with some more game tests in a sec

[pkmaximum]

I have almost tested every cps-2 game there is and they almost all are playable with sound, sry don't have time to post each individual game.

[Vega]

Jesus christ. I cant find a workin version of Super street fighter anywhere

[nexus68]

WOW Dimahoo work great and with the vertical screen it's perfect.

Screenshot gallery of cps2 games:

honestly,, im gettin well pissed off here. can someone PM me please about SSF2T

[samthegreat68]

nj is a perfectionist.

[Vega]

right... apart from the street fighter series... what games should i be lookin out for?

[QueadlunnRau]

Hello All

It’s my first post on this great forum.

Just have tested this great CPS2 emu, on my Japanese psp firmware 1.0. Tested Super Street Fighter 2 & Turbo so far. I have to say I’m very impressed with this release, as I am with all emu’s NJ have created. :)

Many thanks NJ for all your efforts and hard work you do to make this all possible, keep up the great work. :)

by the way great job belmontslayer for the translation

Thanks. I'm downloading this build now. I'm glad he released it!

[QueadlunnRau]

by the way great job belmontslayer for the translation

:D Got so excited because of the test version forgot to say thanx for the translation!

Thank you belmonslayer for your expert translation.

I have a quick question though, on NJ's site does he have a donate link? My Japanese is horrible and am limited to a few nasty words that get me slapped a lot.

[BelmontSlayer]

He dosen't mention donations anywhere on the site...I can't find an email either. That's a true homebrew coder for you! Willing to spend hours coding, expecting nothing in return. I just tried the v1 build, and I notice that there's a second build out!!! :eek: Well, better hog up the phoneline some more. (With my dial-up internet)

[pt9087]

:) Not Bad :)
