Success Emulate UMD on FW2.60 ^o^

Success Emulate UMD on FW2.60 :
  Open and Read file inside ISO by

SceUID fd = sceIoOpen("disc0:/xxx", PSP_O_RDONLY, 0777);
sceIoRead(fd, buffer, size);

  LoadExec ISO's BOOT.BIN by

sceKernelLoadExec("disc0:/PSP_GAME/SYSDIR/BOOT.BIN", ¶m);

Wow! Big news...

But is that the only piece of code required? At just 3 lines, it looks too easy :P

Secondly, I can't help but notice that the code reads:
sceIoOpen("disc0:/xxx", PSP_O_RDONLY, 0777);

Shouldn't it be:
sceIoOpen("ms0:/xxx", PSP_O_RDONLY, 0777);
since it's loading the ISO from the memory stick?

Thanks :)

>> cyanide_nfs
the code is after load the iso to "Emulate UMD"
then can use
sceIoOpen("disc0:/xxx", PSP_O_RDONLY, 0777);
to read file inside iso :P

Again, big thanks for doing this, I'm sure lot of people will be happy :P

Hi 0okm, this are great news!
Do u use the GTA-Exploit for running it?

Hi Ookm you can use load and start module because the eboot.bin it's a prx encrypted and loadmodule work after the kernel exploit not use sceKernelLoadExec("",0); because the loadexec is destroy by the exploit loadmodule it's your best way .

code :
int load;
load = sceKernelLoadModule("disc0:/PSP_GAME/SYSDIR/BOOT.BIN",0,0);
sceKernelStartModule ( load , 0 , NULL , NULL , NULL );

Hi, just wanted to give some extra info about the ta-82 psp's. I have this dreaded version but I was also able to buy a psp with correct motherboard ta-81 (but broken umd drive). It has 2.5 on it so I bough it in hopes that I could change the MB's then downgrade. Too my surprise after 2 hours of unscrewing and dissassembling/reassembling I noticed the following: the ta-81 motherboard did not work in the ta-82 psp. When I changed it back with the original it worked again (luckily). And also placing back the other mb in the partially broken psp made it work again (they now both boot again).
So this suggests the card next to the umd (underneath the motherboard) somehow checks which board is attached and refuses to boot if it's not exactly the same firmware?

Now the question. Is there any other way I might get the ta-81 working in the new ta-82 psp or can I swap the umd drive+casing in psp with ta-81 board? Or can I backup the 2.6 firmware (on ta82) somehow and store that on the now 2.5firmware (ta81) so that I can make both 2.6 and then maybe downgrade it when I swap the boards?

Last question, did you successfully emulate an umd or did you have stability problems when running the kernel function to start the boot file in iso? Just wanted to know if it succeeded (I know you did not release full code or fully working umd emu yet).
