Support NeoGAF

I do believe I said that the HDLoaderor wasn't an emulator. I'm quite aware of what an emulator is. I was assuming that he just wasn't using the wrong terminology. Because what I thought he was proposing was an app that allowed you to play PSP-games from ISOs. Which is completely within the realm of reason, imo.

You said that there wasn't an emulator for PS2 that plays DVDISOs. I didn't claim otherwise, but there is an app that allows you to play PS2-games off of disk images, which would accomplish the same thing, only better.

However, if it can lead to a large user-base, maybe it's a price worth taking. Provided they can get around the issue the next time.

I thought they followed this train of thought with the regular PS systems

This is wonderful news, I still think the BIG issue left is finding a way of tricking the psp into playing games off the memory stick, this will be the hardest part because it may need a modchip.

if you are talking about homebrew games, that has already been figured out (loading through a save exploit ala wipeout pure).

if you are talking about warez, not to go into too much detail but the two obvious answers either seem to be streaming (network or USB streaming) or loading an app that will create a virtual UMD device on the memory stick and loading the virtual device with an iso image. just two guesses.

I'm still buying legitimate games for the PSP.

I just want to know when emulators are coming out. I hope they can make a Neo Geo emulator. Plus of course an SNES emulator.

PSP gets better and better.

That only applies to early Japanese PSPs without the firmware update. That's hardly "been figured out."

nope. the 1.0 is required to use exes created with ELF2PBP. However

I was able to load arbitrary code (NOP's followed by a JMP loop (essentially a 'halt') by editing a Wipeout Pure "ghost" save file. I believe this exploit may be extensible to the Wipeout Pure game save files. If so, this may be a good entry point for a bootloader.

Unfortunately, while executing NOP's is an interesting start ... I'll need to bone up on the instruction set of the PSP cpu before anything useful can be done with this.

The entry point to edit and insert an overflow of NOP instructions is at offset 0xA14 in any ghost save file.

this has nothing to do with 1.0. This is arbitrary code execution inside of a trusted running application. As they say, once they figure out the CPU and hooks into various parts of the system, running code inside of game saves is MUCH more useful because it will work on every system revision the game works on. At that point all you can do is pull the game from the shelves and reissue it as another fixed version.

There is even a way to re-flash your PSP back to the older version.

Check the website at the start of this thread for more info, but apparently it's a pretty scary thing to do.

Link please - can't find it on engadget (is that what you meant?)...?

Ho whoa whoa whoa ho ho!

They have a Hello World running off memory stick!

That = User executable code!

YES

YES

Is the code illegal cuz it's using sony's libraries? If not where can I snag it just to see it running?

 

[Sho Nuff]

The code is evidentaly 100% legally compiled?

[Fafalada]

the psp is also a lot simplier piece of kit compared to the ps2.

Just because it's easier to work with, it doesn't mean it's much easier to emulate.
But that's besides the point really - PS2 has had full publically available hardware documentation for several years now.
PSP obviously has none, and I can pretty much guarantee you that it will never have any aside for possibility of a leak.

Eh, I don't exactly think piracy on PSP will run rampant because of this. Games will probably increase in size over time, and you'll more or less require a 1 GB memory stick. And you can most probably only have ONE pirated game at a time on the stick. It's easy in theory, but very clumsy in reality.

why is this clumsy? You can get a 2gig stick now too. If the games are as small as they are - a 1 gig stick will store plenty of games. Once they manage to hack the games/get the media to burn them

1) psp sales will rocket
2) SONY AM CRY

I wonder how much longer. If the file sizes are that small, this is going to be torrent piratez heaven. I would kill for a PSP media burner so I can bloody use my PSP for its media capabiliies. Goddamn sony and its crippled machine. At least with a DVD machine, I can watch dvds|images+music I made/burnt myself. The Mem stick solution doesn't cut it for media/entertainment.

A PSP media burner...sounds very unlikely, and for what price in that case? And I don't think games will stay that small, games tend to get bigger as they get more complex.
And how small are the games anyway? Didn't someone say 600 MB in this thread, or was that supposed to be 60 MB? 2 gig stick yeah, but for what price? If the price goes down a lot though, it seems a bit more likely.
And I'm sure Sony (one of their divisions) wouldn't be crying entirely, since even with piracy Sony would be making money on memory sticks, compared to making no money at all on modchips.

Why do people assume that emulator stuff is going to work on PSP? It's slightly less capable than PS2, and you can't even get SNES stuff running on that at full speed with sound. If you're hoping to play anything post 80s on Mame on a PSP surely it's going to be SLOWZOR?

But isn't the PSP hardware architecture different from PS2 though? I think the problem with PS2 isn't the hardware capability, but rather the difficulty of making efficient use of it.

 

[borghe]

the firmware on ps2nfo.com (which does NOT contain the ISOs) is not for the PSP. It is only for a PS2 modchip.

understand that we won't see real apps for this thing for probably at least a month. we need a few more gates busted wide open, in particular a few more serious homebrew programs. once homebrew development becomes a regular thing we will start to see stuff like ZSNES and MAME.

Also be warned however, that unless Sony is using widely available APIs or something, distributing such binaries MAY be illegal (ala XBox) if the only way people can compile programs is with a pirated SDK. So even for just emulators we may have to resort to other methods to get the apps if even the act of distributing the compiled apps is illegal.

"It's slightly less capable than PS2, and you can't even get SNES stuff running on that at full speed with sound."

GP32 had pretty damned good SNES emulation on WAY less than a PS2.
It had perfect ST emulation as well, and the Genesis emulation is fecking good too.
PC Engine was also perfect.

As for mame - i think we should be fine all the way through the "golden age" games (R-type, TMNT, Space Harrier etc) and that's what i likes!

 

[jarrod]

Not necessairily, but it helps. Look at the state of DC, GC and Xbox emulation... PSP won't take that long given it's rather straightforward architecture I think. PS2's gonna be like Saturn I bet, we'll get a decent emu around the same time as early 360 & Revolution emus start popping up.

Seconded. With screen capture abilities and online gaming too.

PS2 is hard to get at, and very proprietary. PSP has a common processor (when we're talking open horsepower, BTW, you can't include all of the hardware since much of it is not common architecture, so saying it's "slightly less capable than PS2" or even that a PS2 is "PS2-capable" for homebrew is a misnomer unless stuff like the graphics API is figured out.)
