are there any Firmwear updates for the US PSP?

PSP FIRST EMU !!!!!!!

Damn, that was pretty quick. For those of you tinkering with it, is the compatability with games very high? If so it could have been a straight port of a PC version emulator, if so that'd make SNES, Genny, etc. all pretty close behind in theory, though all would obviously need greater optimization.
My ideal setup would be for them to fill with the appropriate 4:3 aspect ratio (don't stretch like GBA will with GB games) and use the margins for commands, such as save state, save screen, changing roms or emulators. Have that controlled on the analog, while gameplay is done on the d-pad. That'd be a sweet little setup.

Ah shit. Upgrading that firmware really was a huge mistake...
At least my PSP goes to sleep mode quicker now...... (sobs)

Sure, as soon as the 1.5 was released a security hole was opened in the 1.0 version. When 1.51 is released a security hole will magically appear in 1.5duckroll said:The 1.51 update is VERY good news. Remember, the 1.50 patch is the reason why we have this now, so maybe the 1.51 patch will be what allows us 1.50ers to join in the fun too! Just don't update when the patch is up (it's not up yet)!
O.K. here's what I don't understand....if the PS2 is more powerful than the PSP, why haven't there been any decent GBA or SNES emulators for the PS2? I mean there ARE, but they run choppy and not full frame. How can we expect any uppcoming emus to run well on the PSP, which is less poewerful? Can someone shed some light on this? Because I certainly do not want to get all excited about playing say, GBA games on my PSP, only to be let down by crappy and choppy framerates.
And please don't say "Get a real GBA" Well duh...I already have one. But playing them, nice and stretched on that awesome PSP screen would be GLORIOUS!!!

Because no one is really interested in homebrew development for the PS2. It's difficult and there isn't a large interest in it. So far there's a MUCH larger interest in homebrew for the PSP, so there's a much better chance of something awesome happening for it.

It is also possible that PSP's CPU RISC core faster clock-speed and better caching scheme (16 KB of L1 D-Cache compared to 8 KB of L1 D-Cache you have in the RISC core of the EE... the EE has the same amount of SPRAM, but managing SRAM is something that takes more skill than the reduced cache misses you enjoy with a bigger cache
) might allow the PSP CPU to be faster than the RISC core in the EE even though it is a 1-way processor instead of 2-way super-scalar processor like the R5900i in the EE (although getting both pipes to be full all the time took a bit more than waiting for GCC 2.95.2 to do its job 
, it took quite a bit of manual intervention and cache misses do not help you here, they damage you).I think the first explanation was more plausible, both machines are easily capable of doing perfect gameboy and probably GBA/SNES emulatorsPanajev2001a said:It is also possible that PSP's CPU RISC core faster clock-speed and better caching scheme (16 KB of L1 D-Cache compared to 8 KB of L1 D-Cache you have in the RISC core of the EE... the EE has the same amount of SPRAM, but managing SRAM is something that takes more skill than the reduced cache misses you enjoy with a bigger cache
The EE core is a huge bottleneck when it comes to PS2 development, adding more cache to the MIPS processor was a good solution (PSP).
Anyways when people says PS2 is more powerful than PSP the things being compared are FP performance and drawing performance (fillrate mainly). These are the two strengths of the PS2.

GB emu for GBA -> DS!Kulock said:But... the DS _can't_ run GB (unless it's ported, or the emu is included with the game), so how does buying a DS benefit them?
Ok let's not dellude anyone here - R5900 is faster then R4000 - period. There's no arguing about it.
Where PSP is potentially faster is if you start comparing R5900&VU0 (in macro mode) to R4000&VFPU (clock for clock, not just because it can potentially run 10% higher clock).
But the latter won't really help emulators running any faster.
They are - IIRC SNES had full speed emulation running on 200mhz Pentiums, and that's pretty much R5900 class CPU, but at much lower clock speed.
It's just a matter of the effort taken to optimize the emulation - frankly I'm amazed they got something running so quickly, must be using some uber generic R4000 GCC compiler.
Fafalada said:
I am not a pro like you...but my experience with PS2 and Vu0 in macro mode tells that the main problems came from the fact that you need to have data aligned before executin Vu0 macro instructions.
This is of course a problem when you have to execute simple things like a dot product, being the FPU much more useful...But when you have to run long loops then vu0 macro becomes a very good solution.
Shit! If there's a hole in 1.5, then maybe it's a good idea to hop on the PSP bandwagon now. I'd like to wait for confirmation of that, but by then, all 1.5 version PSPs might be sold out, and Sony's bound to be shipping new units with 1.51. This is good news regardless though. Sony should have found a way to make homebrew coding a possibility without opening up the hw to piracy. Like limit the size of homebrew code or something. If you could only run files like 32MB in size, that would eliminate the possibility of running a pirated PSP game, but still leave people to make little tinker games or emus like this. PEACE.

LOL people are happy with an (illegal) emulator, which runs old gameboy color games, which everybody suppose to hate?!1
damn, PSP really needs some games....

First of all emulators themselves are not illegal.
Second of all...please show me these people who hate GB games. People have complained about Nintendo sticking with "out dated" hardware yes. But software? I don't recall seeing anyone on these boards hating on the GB's simply massive library of games. Can you back up that statement?
Third the PSP has gotten more good games in its first month of release than most systems. Someone is in denial.

rrriiight, so everybody is going to run homemade games now.. and the lists which are made in this topic are just for fun....JC10001 said:
I remember a lot of bitching about outdated graphics the past weeks....... Is gameboy color now fresh, or is it outdated?
GAF hates teh old graphics!!!1
and hasn't gotten anymore the last few months, that's great!

I hope one day a DC emulator will make it to the psp although its a longshot =(

Yes but that doesn't change the fact that what you posted is still inaccurate. Roms are illegal, emulators by themselves are not.
Ruud_Luiten said:
So I take it you can't back up your claim then? Because those complaints were made about the DS not about the GB/GBC.
Ruud_Luiten said:and hasn't gotten anymore the last few months, that's great!
You could have fooled me. I've purchased Mercury and Hot Shots Golf along with 9 other games in recent weeks.
Emulators are not illegal, If I want to play my games on other format that is not a Game Boy, I can do it. What it´s illegal is to download roms (and it´s discussable what is wrong about downloading games that are completely out of catalogue).
Second, big news here is that is the first emulator. It´s a little slow and the screen is ridicully small, but for gamers it´s a great new, it´s a nice start.
And I love every consoles and every game.
