REAL custom firmware for PSP

[NoQuarter]

I never recall hearing about epsilon bios being fake!I take it your using it on your modchip of course.
It'd be interesting if we could just flash it to our firmware without a modchip.
Anyway what's the epsilon like?

Yea I was using it on the Modchip. Epsilon is pretty good for an early release (1.1). It is just like running standard 2.71 firmware but with full kernel mode access allowing you to run almost everything 1.5 firmware can.

Sweet
What can't it do?

I would like a really cool new bios and bootshell, although since I have never had the pleasures of booting homebrew on 1.5 I would love for the chance. The stuff Epsilon is supposedly doing is great but, it doesn't look anything differant from the original thing... New icons and flashy interface would be cool. It would be awesome if they made the interface customizable like the GPx2's

For something already developed and current (although just a shell) , You might want to try out PSP-OSS (my favourite)






With Custom firmware you could easily have your Psp boot these as default instead of the standard bland XMB.

Regarding Epsilon custom firmware, I doubt it will ever look any different (or flashy) because it's design piggybacks of your current 2.71 onboard Psp firmware at boot up removing the protection allowing kernel access and then runs from the UP chip Epsilon bios that is based on 1.5 firmware for compatibility.

Epsilon also adds features that allows you to easily recover from any (software) bricking of your Psp similar to custom firmware recovery mode but much more complete. For example, Custom firmware will not be able to recover from anything major and it will fail if your firmware version has been faked to something high apparently.

In the Epsilon recovery mode you can downgrade your Onboard flash regardless of which firmware version it is, for example 2.8 to 1.5 or 2.7 to 1.0 etc, run an official Sony update and you can update the Epsilon Bios. Without Epsilon you would need to rely on unbricking via USB.

Why doesn't someone write a Forth based firmware like Open Firmware? Of course it would have to be simpler so that the end user can actually do stuff with it. Not to mention it would have to support application develepment. You could easily put a custom XMB over that.

Good thinking inigo Montoya and Lodis!!

PSP OSS Is probably the best shell so far (maybe IRshell beats it) but this would solve issues for those with
2.50 and higher with a Ta-082 motherboard.

Give people the chance to customise the firmware more. Recovery option so if one flash doesnt work, the second one will.

I can see PSP-OSS or IRshell being successful in this case

I've been using PSP-OSS ever since the first version came out. Its great.

With Custom firmware you could easily have your Psp boot these as default instead of the standard bland XMB.

I never thought about that prospect. I would love to see that ability in future custom firmwares.

If they made a custom firmware with most of those features up there, I would gladly flash my PSP (not that way ).

wait. isn't there a limit to how many times u can flash ur psp? or are u talking about another form of flashing?
