Think i might have foudn the problem with mine. I had the 2nd memory stick in and noticed that the file shows up as corrupted data. Is it supposed to show up like that?
Click to expand...

Its supposed to be like that.
 
Has anyone gotten Harvest Moon, Final Fantasy V, Super Metroid, and Super Mario All-Stars + Super Mario World to work?
 
I'm having some trouble. I downloaded it, used MSwapTool on the pbp file, and put the files on the memory cards. When I try to run them though, it says on the white PSP screen and doesn't go any further. Did I do something wrong?
 
Got mine working on SNES now. Thanks for all your help guys.



What seemed to fix the problem for me......


I did a full format of the 2nd memory stick (After backing up stuff). Then I did a the swap tool on SNES 9x and it works just fine now. It is slow, but i'll tkae what I can get, not like it's not going to get better.

snes9x doesn't work with the "official release" of the swap trick. On page 10-11ish there's a post about how to do it correctly.

Are you hitting left on the analog stick during the game and optimizing? You should be able to up the clock speed of the PSP to 333mhz, enlarge the screen and skip frame by 2 and it will speed up just about all the games.

Yeah I played with that, got some things to speed up. Im running FF6 only way to speed that up seemd to be turning sound off. I'll keep playing arround with it, and look forward to newer, faster emulators

BEWARE OF THE DOOM 1/2 APPS!

THEY CAN FRY YOUR MEMORY STICK PRO DUO!

Seriously. I just found out the hard way. Luckily I backed up my mem stick's contents before installing Doom.

After it corrupted the card it left all sorts of junk files on the stick. To delete them you have to reformat the mem stick. To do that hook it up to the mem stick reader on your computer, go to my computer, right click the drive that corresponds to the mem stick and select "Format". Leave the label field blank and hit okay.

How did it corrupt it? I've booted Doom at least 10 times today showing various people and never once had a problem. No extra files anywhere to be seen either. What were you doing in game when it corrupted it?
 
I got it to run now, but I'm still having some problems. It just lets me go into the Save directory and I can't do anything else. Now, it even shut down the PSP too.
 
I can't get this shit working...what needs to be on the second ms?? I downloaded the zipped file with all the emus that was posted and put that on both sticks.

the memcard 1 stuff goes on card 1 and the crd 2 stuff goes on card 2

gee thanks for clearing that up. Anybody else?

lol, if you can't understand that explanation, maybe you should get someone to come over and do it for you...

there really isnt a simpler explanation without someone doing it all for you...
 
Listen I'm sure its not that hard, I'm just missing something with the second memory stick.


what I have on the first stick brings up the emu selection screen. when i click an emu and do the swap I get an error messege, so what i have on my second stick is probably not correct and its probably the emu file itself. I'm missing a step.
 
As an example...

MS1 needs: (this is your stick for booting)
/PSP/GAME/SNES9X/eboot.pbp (should be around 17k)

MS2 needs: (this is the stick you switch to)
/PSP/GAME/SNES9X/eboot.pbp (should be over 1500k)
/PSP/GAME/SNES9X/rom you want to play.smc
/PSP/GAME/SNES9X/and so on and so forth.smc
 
when i click an emu and do the swap I get an error messege, so what i have on my second stick is probably not correct and its probably the emu file itself. I'm missing a step.
Click to expand...

What exact error message do you get? and you are running 1.50, right?
 
yes, I got the nes one to work but I had to download the newest version.


For example somebody posted a zip file with all of the emu's and those graphics. Thats what i was using, so what do I do with those to make them work??
 
I have tried the zip and they work for me atleast. It creates two directories when you unzip it, 1 and 2. Put the contect in 1 in MS1 and the content in 2 in MS2. Do not put the entire directory 1 and 2 on the sticks. The directory 1 and 2 should not be included, only the content in them should be.

Ohh you put the contect in directory 1 into x:/PSP/GAME ons MS1 and the contect in directory 2 into x:/PSP/GAME MS2.

Crap, i was affraid of that. I just cant get anythign to work then, tried NES, SNES, double checked that I had 1.50. Im wondering if maybe my roms dont have the right extension, but even then the emu would at least load up right?
Click to expand...

Think you have corrupted the data on MS 2. I have done it myself yesterday several times. Dunno what I did wrong but it has atleast worked just fine in the last 12 hours or so. I suggest you to format MS2 and redo the procedure.
 
There's talk that this 1.5 exploit could result in a 1.5 -> 1.0 flash. Of course, it wouldn't help anyone that's upgraded beyond 1.5, but no swapping would be nice.
 
I would buy a super-cheap MS-Duo just to do the firmware downgrade, maybe this whole thing is part of some incredibly ingenious plan by Sony to drive up MS-Duo sales :lol
 
OK, I'm interested, and the hobbyist homebrew coder in me is tempted to get a PSP right now just so I can be assured that I can have some way to tinker with coding on the PSP in the future...

Here's a question though

Common sense tells me that as long as you use the same rom and the same emulator (barring changes to save state code between differing version of said emulator), you should be able to share save state files between the same emu being run on two different machines...

In other words:

I start playing Super Mario World using SNES9x on my PC/Xbox/whatever
I save using a save state for the emu
I take the save state file and the rom that I'm using, and I copy and paste them to the proper directories in the memory stick to be used on the PSP
I load up SNES9x on my PSP with the transferred rom & save state
I continue right from where I left off, but now on the go

The little coder boy in me says this should be obvious, but I want to be certain before I plunk down a wad of cash on this. HELP ME GAF. :S

Caution: Potential Memory Stick Damage May Occur From Swaploit Use

Please Read:

There have been a few reports of memory sticks going dead using the Swaploit method of running homebrew on v1.50 PSP's. There are several theories as to the causes, such as taking the memory stick out without waiting for the USB connection to close completely, using sleep mode while running homebrew, or being in too big of a hurry when copying to your memory stick. In any case, please read on the procedure before attempting this, and use these programs at your own risk.

The problem with that is does anyone actually have 1.0 firmware? I'm sure whoever tries to do this would probably ruin a few PSPs.

EDIT: I guess people have dumped the 1.0 firmware already.
 
Whoa hoa hoa, be careful with this swap trick, kids. Don't screw yourselves over and trash your memory sticks (or the actual MS reader inside the PSP). I promise not to taste your tears ;)
 
Methix @ PSP Hacker said:
I have ran into a few difficulties. I was researching some things and found out that the dump of the 1.0 firmware is missing some hidden files. If you tried to flash with what I have now it would make you a nice 250 dollar brick. Good news is that people on ps2dev are trying to aquire theese files.

And to clear everything up:

Once this is done, you will need to swap only once. When you swap that once it will run a program that flashes the firmware back to 1.0, therefore allowing you to use homebrew without swapping all the time.

Methix @ PSP Hacker said:
Meanwhile, I have been trying to figure out a way to use the exploit with only 1 memory card. I noticed if you make a directory name more than 31 characters long, the PSP does not recognize it. I had the idea of using directories like /psp/game/ms111111111111~1/ if you get what I am saying.

These folk certainly are a resourceful lot.

Well when that happens I'll be second in line, just after someone else has tested it.....




As for those with two biggish memory sticks... You could reduce swapping by duplicating the emus in the other direction. So

MS1-----------------------MS2

SNES1a--------------------SNES1b

SNES2b--------------------SNES2a


Then when you've finished and are back in the home screen, you can just launch another one and swap back to the original.

Yes, we get it, you have made your point repeatedly. You can stop being a dick any time you like.

I thought I just implied that I'd stop being a dick in the previous post! But your post has reinvigorated my penisness. You lose!

Anyhoo, I think a better idea would be to rig some sort of proprietary launcher that you could return to with the HOME key -- that way you're still staying in exploit mode.

Mmm...need DiVX player
 
i just downloaded: mswaptool_02_psp-dev.rar

now when i open it on my computer i can install it.

where should i install it? on to my PSP or on my computer?

if its on my PSP then in what folder should i install it?



i cant find a step by step guide on how to install the exploit.

for psp sms it doesn't see any files are they supposed to be ziped or in sms format?
Click to expand...


Have your roms in .sms format. Which version of the emulator are you using btw? I could never get version .04(the newest one) to work,it would never show any roms after the emulator loaded. I switched to the previous version(v3) and everything works now,though this one has no sound and it is not full screen. Eventually an update will fix this though,its very playable as is though.

Btw-if you have it then load up a sweet gem called either Attack Sub or Sub Attack(it goes along thelines of something lije that.) I haven't yet tried it (I've only emulated it with my DreamCast) and it wasreally one very nice game. But anyway the rom should work. Its the Master Systems equivalent to In the Hunt. I'd swear that Irem might of had something to do with it because it plays *alot* like in the Hunt did years later.

on your computer. its a tool that changes some headers in the emulator and splits them into two bootable files. those files should then be installed onto the memory sticks..

that said it seems that my sandisk has some major problems with this laptop and its inbuilt memstick reader. files can get corrupted. cant delete corrupted files and when i do they immediatelly reappear with a size that is 0 bytes big. and everything else I put onto the memstick gets corrupted aswell. movies gets artifacts etc. no wonder i have a hard time running emus and their games. if the emu isnt corrupted the games are and vice versa.
 
whoa...last night i thought this hack was useless. now that ive got everything set up it rocks. honestly, you dont need to be super quick qhen swapping. ive dropped my roms memcard trying to put it in, regathered, opened the memstick flap and put it in (about 9 seconds) and it still works. if it doesnt load youve done something wrong.


and OMG donkey kong country runs near perfect! nba jam rocks hard too

Wish I knew. I was able to get it to load properly several times as well but suddenly I wasn't able to. I checked the card and the doom-psp directory was toast.
 
guess you have seen it, but now there is a one-memorycard swaptrick out.

It works by setting the psp to sleepmode after launching.. and then change card, and resume.
seems to be less violent too since there should be no current that could destroy the card then?

how does this work?

but you said :

"and then change card"

doesnt that mean you still have to have 2 cards?
 
if any aussies here need a spare 32MB pro duo for the exploit i have a spare 3 il offload em cheap pm me
 
Load MSwap Tool, then select your PBP File and hit generate.
The program will create DIRS: MS1(Dummy Stick) and MS2(Real Stick)
MS1 contains the loader info basically, MS2 Contains your homebrew
and your roms/whatever else.
Click to expand...


does this mean i have to add all the ROMS, EMUS and stuff in to the MS2 folder?

should it be like this?

PSP/GAME/MS2/my roms and emu?

or should the roms+emu and the MS2 folder be in the game folder?

Well, you've now got as long as you like to swap the card, so you can stick your memory card into your PC and move folders around. Not exactly ideal, but it means you can get it working with one memory card without cat-like reflexes.

I was playing FFV a while ago on another emu. I took the .srm from my file and put in the SAVE folder of the SNES emu and it worked! .srm files are universal amongst SNES emus...

ah ok, shit but then i need a Card reader on my PC!!!!

ahhh i hate this shit, why cant they make something thats easy to use :(
 
Could somebody make me a video of any Sonic game running on the megadrive emulator please? I wanna see how good it looks on that beautiful PSP screen. :D


I hope the new European firmware gets cracked shortly after launch, I want a piece of this emulation lark... :(
