JEEZE PEOPLE !! YOU CANNOT DOWNGRADE TA-082 PSPs THE HARDWARE CANNOT FREAKING USE 1.5 FW..... IE INSTALL WINDOWS 95 ON A 2006 MACHINE, THERE IS NO COMPATIBILITY.

Yes you can to both, with some clarification.

The TA-082 should not downdate to anything below 2.5 (note that 2.71 is above 2.5). I don't remember if 2.71 SE-C works or not, but 2.71 works beautifully with Hen-D. The hardware is built not to accept older firmwares and will result with a new expensive paper weight.

Why can't a 2006 machine run Win 95? You might mean that an NTFS formatted HDD isn't compatible, but that's different right? You can format your HDD anyway you want. Most flash memory (like your Memory Stick) also run under the FAT/FAT32 file system, you could install W95 and boot from it if you really wanted to. You can even install it on a FAT32 partition of your regular HDD.

Yeah, too many people are upgrading without any thought. My brother just bought a PSP at the airport coming home on military leave and it was a 2.70 or 2.71 TA-082. He upgraded it right away to 2.81 to play Socom 2.

Needless to say he got an earful from me about what a dumb move that was.

is this also for the TA082?

hummm... i looked at the source and i was first quite sceptical. What the source is doing is probably trying to unprotect the first 8 MB (which is normally only kernel-accessible) in a similar way as http://forums.ps2dev.org/viewtopic.p...ght=0xbc000000

That doesn't mean that code is running on kernel mode thanx to an exploit but has unprotected a memory region so a user code can read it and dump it on a memorystick.

but in a certain way, we might be able to write a lot of patched code on this protected memory this way and let normal kernel functions to execute them. So, yes, a downgrade might be done this way.

i hope so hilde

soon 2.8x will be downgradeable

hmmm homebrew what a nice thing

**IHadToReRegisterwtf** · December 21st, 2006, 08:23

What the hell's the point of this topic? You can already do homebrew on 2.8 with the new eloader. You just can't run isos yet(which are illegal and this topic is basically encouraging pirating).

Since you can already do homebrew on 2.8, whats the point of talking about downgrading unless you want to pirate isos?

**belialone** · December 21st, 2006, 08:50

no dude kernel access means downgrading could be done on a 2.8x psp
its better to use 1.5 or 2.71se than 2.8x

this thread is like a preanouncement of a downgrader :thumbup:
