Was looking for an update for other readme's, when I cam across to NJ's homepage. There, although in his readmes, he was saying he won't be doing CPS2 (in the CPS1 readme), but it seems like he is working on CPS2 as well.
BTW, haven't gone through the search on PSPU during the time translating the page, if this was up please feel free deleting this. Also, as of usual, if this wasn't the right section to post, please feel free tossing it around. To view the current pictures, please refer to: http://neocdz.hp.infoseek.co.jp/psp/cps2.html Sorry don't how to impliment pictures inbetween texts, so, allow me just to do the text translations. For the pictures, please refer to the above URL. Thanks much. *** Translation *** Although I wasn't intending to creat this, wanted to make the CPS1 more faster, so during modification of C68K, this came up well, so managed to playaround with this. Don't know this will be open to public at this stage. Will be doing some works in it, but please do not blame me if I quit. At the beginning, if I were to make one, thought of using MAME's musashi M68000 core (although tremenduosly slow on PSP), but during the modification of C68K, this became working with more speed than intended. After doing some tests, I came to a conclusion of the sprite's priority process was simpler than the CPS1, and this is the biggest fact. But, basically, the available memory is way too short. If I didn't have the ROM de-cryption XOR table this was to be alright. The PSP carries 32MB memory, but the 8MB will be used for the PSP's OS and such, so theoretically there is only 24MB left. Within this 24MB, the program are would be used for approx 4MB, realistically, 20MB will be it for Game ROM data area. If there was 32MB, or atleast 24MB more, things would be much easier.... Have tried the playback of the sound. Some problems which didn't occur on the CPS1 came up. There isn't much problem on the BGM, but the SE voices seems to crack up and could be annoying. Tried decreasing the volume and such, but this seems not an easy task. Also, sprite's priority still have some weird parts, so, problems here has to be solved as well. Have implimented the same Cache System as of NEOGEO Emulator and played around. As thought, it's not a playable game. My feeling towards this decreased. Cache file reading is slow, but before that, the game itself is very heavy. Probably the reason for this is the smooth animation it has. Every frame texture is re-written and the Cache (not memory cache, but sprite cache) doesn't work. Disabling auto frame skin is still at this stage. With sounds playing. Have tried old games. Firstly ddtod. This can be played normally. Sound playing on 22KHz. Same old game, but fighting games are not good. ssf2xj. Additional: for ssf2xj, disabling autoframe skip will bring the game to 60fps and playable. I need to look into autoframe skip process. Between games, there are alot of differences. ddsom. New monster and magics do give process loss, but, still a playable level. Probably optimizing the Cache to the game, then this would be playing normally. Shooting Games. progear and gigawing. Seems playable if Cache is optimized. Conclusion. + Fighting games are probably un-playable. (Works but not a playable speed) Although if the memory increased, still, due to the PSP's process speed not enough, this won't be a worthy emulation. + Puzzle and verticle action games would be playable. + Shooting games would work as well. One more, currently, if cache file is created for all games, it can launch them with sound. (ofcoarse, the ROMs has to be decrypted) Although some of the screens are still funny. *** Translation End *** Although as stated in the translation, the fighting type might not come as playable, but this sure looks promising. *** Edit *** Added pictures Hope this helps,

So is this the same guy that made CPS1? Cause that was like perfect and its only Alpha 1 build. But Fighters would be unplayable you say... I wonder if that would also include MegaMan 2 Power Fighters?

heres what his web page has to say.
That with the notion that where you say whether CAPCOM CPS2 Emulator for PSP (test ver.) CAPCOM CPS2 Emulator test version binary Download which it is moving, test version is released. It advances job, but throwing out midway, without grudging. Still as for emulation far when it is complete, as for bug a large quantity there is. Grapple please think the game that at the speed which you can play it does not operate. Even if, assuming, that memory could be increased, these games probably will be because with PSP throughput is not enough, you cannot desire comfortable emulation. The action game of the puzzle and the side scroll is play possible in that appearance. Also shooting operates to that appearance. Volume adjustment of future schedule sound. Because considerably there is a variation in every game. Bug correction of drawing and processing in every final adjustment game size of the texture territory is modified must check entirely in optimum value, because, it is the job where time is required. This which in every game modifies memory cash in optimum type and it is the job where time is required. The reason where the emulation of CPS2 with PSP is difficult memory is not enough basically at all. If there is no XOR table for the encoding cancellation of ROM, it is still to be good but. PSP has loaded the memory of 32MB, but 8MB in order to use with OS and the like of PSP, really only 24MB can use memory. Because as for 4MB it is used in the territory of the program, you can use substance 20MB as the data area for ROM of the game. … If after 32MB, at least 24MB it is, although it is easy. Either VRAM is not enough. The indicatory frame and the drawing frame, after guaranteeing the frame 3 picture for picture synthesis, the texture territory for sprite must be guaranteed with 4MB which passes, it is the case, but being earnest to guarantee the texture amount for the frame which presently is in the midst of drawing the amount which turns to cash it is not possible with guaranty. Whether saying, drawing up the hypothetical frame in main memory, because synthesis (the same method as the emulator for Windows of MAME and the like) it did the picture, present condition compared to furthermore speed just falls and. Lastly, the throughput of CPU. Because approximately drawing ability is high, somehow it has covered entire speed there, but. - It returns to the △ top page which returns to the page first |

Awesome, this is such a good emulator!
If anyone's wondering what rom they should get, try Giga Wing. It runs really smooth in game and plays well too (but the Dreamcast version is better )I'm going on the scout for some other good roms now ^_^ EDIT: Mars Matrix is another shmup, and works well with short periods of lag. Cyberbots refuses to work, so don't bother downloading it.

A lot of games seem to frequently load in-game, even the smaller ones, but Super Puzzle Fighter runs 100% so I'm happy!
This guy keeps dishing out amazing emulators! AWSOME!

MegaMan 2 Power Fighters ran perfect for me, I even bumped up the sound quality to 22kHz and it ran fine.
These games also ran good Dungeons & Dragons: Tower of Doom Dungeons & Dragons: Shadow Over Mystara Giga Wing X-Men: Children of the Atom (runs choppy for about 5 seconds into the fight, but then its running 60fps afterwards) There are some pauses when it is loading from the sprite cache, but it doesn't happen very often. Overall I am VERY impressed with this emulator, I really did not think CPS2 would be possible as these speeds on PSP. |

He states that there isnt enough memory on the PSP to play larger roms is why he mainly stopped right? I'm wondering why doesnt he do the method Daedalus uses to play larger roms like Zelda. Are cartiges ran differently then arcades?
EDIT Okay, call me a noob but I never messed with CPS2 emulators on either PC or PSP. So do I get this to work?? What is needed on the memory stick? Just the 1.5 folder and not the converter right? Where do the converted files do and how? Any help would be appreciated guys. For some reason of all the emulators, these one has gotten my stump. Last edited by lunasicc; 08-04-2006 at 04:33 PM.. |

i'm very impressed, i think the speed is incredible already.
just to let you know. street fighter alpha runs at 50+ fps if you turn off autoframe skip and put frame skip to 2. gigawing runs fine, even with raster effects on. i'm about to try alpha 2, i'll let you know. and to who ever said marvel vs. capcom works, you can't even load it. a message pops up saying that it doesn't work and to not even try. EDIT: alpha 2 works with the same setting as alpha. a bit of slow down to 30 fps at the character select screen. but during the actual fight, the fps hovers around 45-48. still smooth though. EDIT #2: alpha 3 works. fps is ok, running at about 45 during the match, but it isn't smooth at all. it frequently dips to 25 fps during some character animations, which almost makes the game un-playable. i thought turning off sound might help, but it actually made the game run about 10 fps slower. like both of the others, a frameskip of 2 works better than auto frameskip.

It's apparently just a little cosmetic fix for the title of Progear, nothing important.
Progear works well anyway (side scrolling shmup).

Tried this last night and was stunned to say the least!
Super Street Fighter II - The New Challengers runs at 60fps on most stages but drops sometimes to 40-50fps, T-Hawk, Cammy (albeit with gorgeious 44.1khz audio). Looks amazing though, plus I now get to play the best Street Fighter game ever on the PSP.

What do you want to call it, Capcom Play System 1? I'd rather call it 'CPS1', for simplicity's sake.
