4.93 EVILNAT (Cobra 8.5)

PS3 4.93 Evilnat w/ Cobra v8.5 - (CEX/PEX/D-PEX) 4.93

Thank you @Evilnat for your great work, I noticed another small error and although when you download something via the browser, I noticed THAT the download button is not quite in the right position again, so that was also in the 4.92 Evilnat but then you fixed that, so where there is download in the background or just in the PSN. This should still be fixed and, could you install the new Emu PS2 version? The fan function has been improved.

Thank you very much for your work and what was meant by the browser is whether you could change the search engine of Google on DuckDuckGo?
 
:sang banghead: IMPORTANT NEWS FOR CFW USERS: Evilnat's Github repositories have been taken down.
For now, you won't be able to update the CFW version via the internet until a solution is available.

Can you show this on screenshot? I think I will stay at 4.92.2

Hello dear @Evilnat, I don't have an X at the moment and I hope that you can also read it here?
I read that you are currently looking for a host and you are now also on Gitlab, have you tried to upload there once and I thought that the good servers have.

And maybe you can also upload your update to PS2 EMU and Xai plugin to Gitlab?

There is also Codeberg as an alternative for Gitlab and Github. They are also very good.

CFW 4.93 Evilnat updated in MEGA folder:
  • Fixed update via internet (slow download...)
  • Fixed error 80028EA8
  • Added xai menu with PS2 Dynamic FAN Control (by kozarovv and @mrjaredbeta)
  • Updated PS2 EMUs (by kozarovv and @mrjaredbeta)
The host for CFW update via internet and patch downloads from xai_plugin has been updated. Unfortunately, this host is slow at downloading. I'm keeping it until I find another one, as this one fixes error 80028EA8

EMUs updated. Thanks to kozarovv and @mrjaredbeta for his research, both are awesome! Here are the details about them:
EMU DATA said:
## Custom dynamic/static FAN Control values for PS2 EMUs (By kozarovv and mrjaredbeta)
The latest emulators introduce a single new feature: fan settings loading on PS2 game boot. Now, you can simply place the correct file into the folder, and the chosen fan mode will be enabled automatically. The file still needs to be edited manually, and there are no plans to add file saving to the emulator GUI, as it's a lot of work for something most users will set once and forget.

fan.bin layout:
- **byte[0] =** is_auto_mode
- **byte[1] =** max_temp_for_auto
- **byte[2] =** manual_speed

If byte[0] is 0, manual_speed is used
if byte[0] is not 0, max_temp_for_auto is used (value 01 is recommended for future compatibility).
The file must be exactly 3 bytes, with unused values filled with 00 or FF. The release includes a file set to auto mode with a 65°C max temp.

Safety measures ensure incorrect values are clamped to safe ranges (60–75°C for auto, 21–80% for manual speed). Values are hexadecimal, e.g. 01 41 00 means auto mode with a 65°C limit (0x41 = 65).
The file allows setting max temp in range 60-75°C (3C-4B), thus make possible values which are normally unavailable in GUI like 63, 67, 72, etc.
Place the fan control file in **dev_hdd0/vm/ne/fan.bin** for netemu (create the 'ne' folder if needed) or **dev_hdd0/vm/gx/fan.bin** for gxemu (create the 'gx' folder if missing). These files can be overwritten by LV2 apps like Webman MOD, option to set auto fan speed can be added to Webman MOD when emulators prove to be stable.

Since fan control is critical feature, **USE WITH CAUTION**.
Fan features require firmware with a patched service manager, such as Evilnat 4.92.2/4.93.

What's next? I need to rewrite all my patches for netemu. While they work fine and should be safe to use, code quality is terrible. New features were added on top of ready to release code. Some changes were squeezed into the middle to add bugfixes, etc..
I need to backport notification hack from gxemu to netemu to enable ingame fps and temps display. Gxemu need some cleanup too, but it is much better in term of code quality.
Finally. I started work to enable fan control on ps2emu. It will take some time as every emulator have very different vuart implementations and additionally ps2emu is little bit short on code space.

Thanks to kamilb880 for testing and some cool ideas!

Thank you so much, @Evilnat, for the update. You're amazing, and thanks to all the other developers for their hard work and for supporting @Evilnat with his great CFW.

I second the Codeberg recommendation - It's worth setting it as a mirror to Gitlab, because it's EU based and therefore not subject to DMCA claims. Having one US and one EU mirror gives you better survivability because there's no single jurisdiction that can take down both.
 
Hi, i'm on 4.92.2 cex, it is unclear to me how to install the patches in the mega folder. Should i install the cex vhs_update_fix? And then can i install the xai and ps2emu updates over 4.92.2? If so, which one do you suggest? Also there is a not available file in the fixes folder, i guess it is included in the latest update. Since i do not care about online, that's why i have the 4.92.2, would you suggest to upgrade to 4.93 anyway? Thanks

I feel like at a certain point we need additional version numbers to differentiate between the 3 versions released so far. Someone might not notice they are on an old version, since the version numbers is the same.
Like 4.93.1.3 currently

Update to the newest 4.93, it has everything already fixed.
 
@Evilnat, many thanks for this even though I probably won't update.

Please could you (if possible) add a cell overclock in a future update. That is the only thing that would be worth updating for, at least for me.

Also, I am not sure if its my eyes, but its hard to know what changed between versions, like from 4.92 to 4.93, not from Sony's side, but from the CFW functionality perspective.

CFW has no changes over base OFW besides the usual patches. For proper CFW feature updates, you should check Evilnat's CFW and Cobra payload changelogs.

There you can find the improvements and fixes implemented in the new CFW release.

AFAIK no new changes other than those pulled from OFW (AACS keys, SSL certificates) and the auto-updater patched to use Evilnat's new repos after the Github got taken down.
