"Epsilon BIOS can be compared to a "bootloader". It is stored on the U.P. flash memory and executed when your PSP is powered on. Once Epsilon BIOS is running it loads and "piggybacks" the real firmware from the PSP flash. Currently only 2.71 firmware is supported, you must upgrade your PSP onboard firmware to 2.71 in order to use Epsilon BIOS. If you attempt to boot Epsilon BIOS with an unsupported firmware version you will be taken to the recovery menu where you can upgrade the PSP firmware. The great thing about Epsilon BIOS is that since the "bootloader" always runs before the real firmware we can apply whatever patches are necessary to disable whatever protection Sony tries to add in the future, making a U.P. modified PSP using Epsilon BIOS very future proof." |

Since when is 1 day old? sheesh.....
It would be great if 1.5 users can use this firmware without the modchip ;)

Most impressive. But yeah, since most DevHook users are too cheap to buy a single game I'm sure they won't be shelling out for a modchip unless it does something seriously amazing or they end up left with no choice for whatever reason.

Because of the brillian work of dark_alex and others, the mod chip is only good for unbricking. Lately with the 2.5+2.6 kernal access, we are getting all the perks from the chip with only a few mouse clicks instead of soldering that could do permenant damage to your PSP.
hmm, perhaps someone could disect the epsilon BIOS and non-modded PSP users can use it (or parts of it.) we'll have to see what happens in the future.
#6 i bought me and my katamari, i plan on buying all the games i can instead of downloading the ISOs.

this is old and epsilon suck. u can do all this in devhook just u gotta poweroff more, no biggie, thats better than dishing out $100 - $200 for a modchip.
i also wonder why you need to upgrade to 2.7 for it. i mean there really is no reason you should have to upgrade. cuz the bootloader is run off the modchip and shouldnt need to read the flash firmware before loading up the fgirmware on the modchip.
I also checked out that EZIP iso compressing they have, 1) you cant decompress them yet. 2) the compression is junk and isnt even as good as cso.
DEVHOOK IS BETTER

This is cool but as #8 said devhook runs more games, and is free. Plus you don't have to open up your psp and use a microscope to install it. A friend of mine who had a 2.71 psp has one in his psp and out of all the ISOs I gave him only about half work. So I guess it is ok if you have no other choice.

I'm seeing tonnes of people constantly whimpering "b-b-b-but Devhook!".
Guys, this is awesome! You're only putting it down and saying it sucks because you can't afford a modchip. Get over yourselves and try to appreciate that something new and impressive has come. Just because you can't be a part of it doesn't mean you should put it down. Go back to your pirated videogames, kids.

so this is essentially making money off illegal stuff and software piracy. The only thing that's even worse than illegal stuff and software piracy. I hope nobody ever buys this *****.

Does this mod chip support user with mobo TA-082
If not then I doubt anyone will buy it
Soon 2.71 will be hacked anyway.

I would rather have my 1.5 PSP with DevHook installed tbh.

I can afford one, and I was going to get one but after seeing it in action on friends psp I was unimpressed. Why spend $90 plus the time and effort to install it just to have something with less functionally of devhook. For me it isn't a issue of price, if this was $50 and devhook was $50 I would get devhook since it is clearly superior. If you upgraded to 2.71 and this is your only choice then fine.

I can understand people liking Devhook. It is a wonderful tool that has delivered paradise to 1.50 users. The reason I like the Epsilon is because of its simplicity, and it is futureproof (Devhook is always 1 step behind $ony), and the recovery mode makes a PSP unbrickable, which is good for people who like to experiment with x-flash and other dangerous tools.
To each his/her own I suppose. Everyone should just stick to which ever way best meets their needs.
The only thing that bothers me here is that a lot of the people posting that it sucks and its useless are the same people that were screaming FAKE just a few days ago. And now that they've been proved wrong (and immature), they're screaming bloody murder and hiding behind devhook and declaring the EP bios as useless, saying "It Sucks" while clearly not knowing much about its capabilities.

@21: you only need 2.7/1 to boot into the firmware itself. recovery menu features are available regardless of firmware version, and are loaded straight off the chip, i suspect.

Even though I agree with you to some extent, can you please name any MAJOR differences between Devhook and the chip? I mean Dark_Alex's custom firmware can unbrick PSP's as well. Im sure the Mod chip is great, but I rather have Devhook for free, even though it is a step behind the Undiluted Chip.
