Playstation Emulator for PSP Released 76

Joan Cross writes "Today sees the release of the first Playstation Emulator for the PSP to play commercial games; the emulator plays games such as Ridge Racer at up to 10fps, and once dynarec is added full speed is easily in grasp. The emulator works on all PSPs except those with firmware 2.80 and higher." Update: 09/26 12:19 GMT by Z :Fixed dept.

      No, not that...the other thing.

    once dynarec is added full speed is easily in grasp.

    Yeah right. The authors of the PSP SNES emulator basically stated that even with dynamic recompilation and a full rewrite, they could see no more than a 10% speed increase over what they already have, which is playable, but not full-speed.

    Somehow I highly doubt that the PSX emulator (at least the homebrew one) will accomplish that feat.

      Absolutely right. Running MIPS code at full speed on a MIPS CPU is clearly impossible, even with a 4-5x clockspeed increase. It'd be like running win32/x86 apps at full speed on Linux/x86 - as if that's ever going to happen!

        Running MIPS code at full speed on a MIPS CPU is clearly impossible, even with a 4-5x clockspeed increase.

        Running MIPS instructions on a faster MIPS core isn't the problem. It's emulating the support hardware of the Playstation -- the sound hardware, the Geometry Transformation Engine, the Data Decompression Engine et al -- that requires a lot of overhead, and has to be done mostly in software. Even where the PSP hardware offers a close analogue, you'll need at least twice the power of the original Playstation, to translate the opcode and then execute it.

        • we've got GHz of power (whereas the PSX had a 33 MHz core) and we've got far more than it's paltry 2 megs of RAM (I believe the PSP has more, so no wonder the PSP emulator is lagging,) for video memory. Then we haqve more plain RAM, at far faster speeds than the PSP. Emulating opcodes will not be a problem, even within an emulator, even in the tangled wreck that is Windows. BTW - ePSXe is nearly perfect with Pete's GPU/SPU plugins, so if anything, just up the Frame skipping to match real-time framerates.
          • What the hell are you talking about? GHz of power? Windows? The thread is about an emulator that plays PS games on the PSP, not on a PC!

      It's all fine and dandy except...

      1) If you want to play new PSP games, they require you to update your PSP OS to the latest version. So, don't expect to be able to play anything that's "X.X and earlier" if you buy and play new PSP games.

      2) PSP games are pretty limited. So, maybe you won't have much need to upgrade. =)

I'd even be willing to pay for the software if it was good, easy to use, and not too expensive. Oh well, a guy can dream.
    • Sony IS developing a PSX emulator for the PSP, due to release later this year around the Ps3 launch. It will cost money, (obviously) but you DID say you'd be willing to pay for the software...
      • Absolutely, I'd be willing to pay as much as $30 or $40, but if it came out at the Ron Popeil friendly price of $19.95, I'd be even happier. I have a lot of old PSX games lying around that I'd love to be able to sneak off into some room in the house, away from the kids, and play without too many interruptions. Yes, I'm a baaaad man!

              At that point you can just mount a battery and LCD on your PS1.

It's frusteratingly little... Where the hell is the next Tactics Sqeenix? We'll buy it as long as it is more like the PSOne version and not like the GBA version. Hell, it'll sell a lot of systems.

I don't mind playing tethered to the wall, or even carrying around the gear. It's just the having to hold the controller instead of the unit itself (and thus having to set the PSone down somewhere) that kills it.

      The problem with the homebrew scene on the PSP is that's its basically a front for pirates. While there are people just interested in homebrew, it is quite obvious from looking at various sites that all the tools for downgrading / exploiting firmware, emulating UMDs, ripping UMDs, running isos from memory stick etc. are basically piracy tools and used as such. No wonder that Sony are updating their firmware as fast as they can. It's tough on genuine homebrewers, but what do they expect?

  • From what the linked forum thread states, this emulator seems to be based on the code of PCSX and others, breaking the GPL license.

    This emulator is a deriative work of PCSX (see the linked forum post), as well as the P.E.Op.S Soft SDL driver, and SDL itself. It violates the license of all three of those by not releasing source or an offer to get the source. (Heck, it doesn't even acknowledge that its a deriative work of any of them.)
    • by KDR_11k ( 778916 )
      Are you sure that it's an SDL derivative and not just using SDL? There are quite a few commercial games using SDL that aren't opensource either.

    ...users of [firmware versions] 1.5 and above obviously requiring the eLoader exploit.

    ...which still requires editing of savegames, which still requires a copy of GTA, which still isn't legal (at least according to SONY). Why can't SONY come out with their own, viable version or a PS1 emulator already? Besides, who wants to play these games at a max of 10FPS when the human eye can see at a solid 16FPS [100fps.com] itself?

    • and don't get me wrong, it's a very cool concept... I just don't see this as practical in the least (at least for now!)
    • actually, I'm using the current version of Eloader on my PSP (firmware v.2.60) to play NES/SNES Roms, and it 1.) requires no editing of savegames and 2.) Requires no copy of GTA.
    • FPS might as well be Hz when it comes to game frame refreshes. The human eye can at average discern 70 individual frames per second (that'd be 70Hz for you uneducated people...) and generally organically-processed motion blurring keeps that around 30Hz (or 30 FPS, whichever you prefer) Where you get your 16FPS is bullshit. Right around 30 pure FPS from my webcam is real-life motion, and I run one nice 64-bit system. You still using an 8-bit 8088?
      • The human eye *can't* perceive 70 frames per second. It can only detect 20 or so FPS, which is why movies use a frame rate of 24 fps. The flicker that people used to complain about was because of interlace not frame rates.

        The drive for high frame rates is driven by people who need the latest and greatest, not by any real biological demand.

            Sorry, but I understand the biology of the eye quite well, thanks. I don't need to be educated by children.
    • The page you linked to referenced 18fps, not 16fps, as the point at which the eye ceases to see flicker for a movie. But as they point out, this is due to a number of factors, including the "blur" (which I assume is very visible on film-based media but is less likely to appear in an FPS as that's, essentially, three dimensional anti-aliasing.)

      Interesting link. Given the limitations of modern monitors, I wouldn't be surprised if there's a lot of research into how to create appropriate "blur" in the future

      That happened back in 2004 when Sony started to terminate CLIE. It has little to do with PSP, which was never intended to run homebrew. (Another company, on the other hand, mostly looks the other way.)

          Yes, the DS has a 256 KiB firmware. There have been two major versions of the firmware, with some minor revisions to each (e.g. to support DS Lite brightness control). However, Nintendo doesn't plug holes nearly as often as Sony: a DS Lite purchased in August 2006 is still subject to the same exploits (PassMe2 and NoPass) as a DS from October 2005.

              I don't think "and buy games" applies much to the GP2X. Do native commercial games for that system exist? The only current gaming handhelds I can think of that have both commercial games and a stable homebrew method are GBA and Nintendo DS.

      They have screwed the homebrewers because there is a significant overlap between the homebrewers and the pirates, in the tools they develop and the sites they inhabit. I'm sure Sony have no particular beef with genuine homebrew software but they sure as hell do with pirates. Homebrewers are just caught in the crossfire, and that's just too bad. You could hardly blame Sony for wishing to protect their profits and the long term success of their system by updating their firmware to combat the various exploits

        "Yet" being the operative word, my naive little friend...
