Hacking Just a couple of cfw questions I hope can be answered...

[The Viztard]

Just a couple of questions:

- I'm currently on 5.50 Prom-4 on my PSP 1000, and I was wondering if it is at all worth it to update to a 6.XX cfw? I've heard that it is a pretty simple process.
- And if so, which cfw is recommended?
- Can I just update over my current cfw or would some sort of uninstall of Prom-4 be required? (Or would I just install a 6.XX ofw and then install a 6.xx cfw after?)
- Would my game saves be all right (as in playable), or would they corrupt somehow?

Any help/comments are appreciated!
Thanks in advance for the help!

It's the most compatible firmware with games to date, no save file corruption, and even NoDRM for DLC built into it. However, about those saves, I remember GEN-D3 having some weird error with those (hence why I mentioned no save corruption), making the saves work for only that firmware. I'm not sure if it applies to Prom-4 as well.

If you're still willing to update, just get on the latest official firmware 6.60, and download the 6.60 PRO-B10 CFW from this page.

Just ask if you've got anymore questions.

Thanks! Uhh, yeah, I'm still interested for sure. It's just that I obviously want to be able to play my game saves from Prom-4 on PRO (so no starting over and stuff) if possible, yaknow?
Yeah, I was on Gen-D3 before Prom-4 and I was scared for my save files from Gen not working on Prom-4, but I asked around and it turns out they were fine from Gen to Prom-4. Then again, they were both 5.50 fw's, while this would require updating to 6.60. Soo...crap. I don't know.

There's an application called SaveGame Deemer that allows you to update your save files for a compatible firmware base if they're read as corrupted. It also requires a decryption key for that game so it can be unloaded as raw data and converted. It's an extensive process if you've got a whole bunch of saves. Trust me, I've been through this crap. >_>;;

You can also use MagicSave, which is a lot easier, since you use it while loading the save.

Ugh! I want to update...but it seems like such a hassle to make sure the saves work after I update to PRO from Prom-4. D: Thanks for the help though.

I didn't have any save issues after updating.

Hm? That's kinda what I was wondering, I haven't actually tried it myself for fear of the game saves from one not being compatible with the other. So going from 5.50 Prom-4 to 6.60 PRO shouldn't create any save issues? As in previous game saves from Prom-4 should work fine on a newly installed 6.60 PRO?

 

[Rydian]

Some people have issues, some don't, I haven't had any.

Why did someone said like ''WTF? upgrading psp 1000 to pro is a crap''
and i believe its someone from here.

 

[Rydian]

I didn't see that.

No one has ever said that that I've seen in my entire GBAtemp life.

Plus, I had absolutely no save problems either. I was like you, and after updating (to 6.20, but 6.60 is no different, besides anti-piracy measures and cosmetic changes) none of my saves were unusable or corrupt.

I've probably had a single game save corrupt on me but it was a PSX title and to get it to work, i kept changing the POPS to get it to work and saved often... Upgraded CFW, remembered to remove all Plugins due to incompatibility and a single PSX save corrupted... All PSP saves were fine and 99% of PSX game were fine too... The one that i kept on changing the pops around on was the only one that gave up the ghost....

Stick on PRO when you get it

 

[The Viztard]

Ah, alrighty. Well I guess I'll upgrade then. Meh. Haha. Thanks guys.

I agree with this.

I believe one of the Pro updates fixed the whole corrupt saves from Prometheus problem. Apparently the issue was that Prometheus uses the wrong encryption key for saves so when a later firmware tries to load them the correct way it fails.

I believe its 6.29 im not sure

 

[chaosdarkneo]

Uh, no, it's PRO-BX (the X being the version that fixed it.)

I'm pretty sure PRO-B6 fixed this issue, so if you update to PRO-B10, you should be perfectly fine.

 

[MadHouse38]

Okay so every latest pro have fixed like pro b10? great
