To quote from Habib (SRC): 4.81 STARBUCKS v1.02 + COBRA 7.50 CFW
CHANGELOG:
What's New:
1. c00 without license
2. possible bug fix when downloading pkgs
3. Cobra 7.50
4. sc 870 patched (get_idps) Sony blocked in 4.55, no more using lv2 peek etc to get idps XD
Cobra 7.50:
PS2 with config:
I tested it thoroughly to make sure nothing is broken and nothing was
Original discs:
The only changes are in storage_ext.c (which is firmware independent) in functions related to disc authentication/identification.
PS3 games can be burned to regular CD-R, DVD-R SL/DL, BD-R SL/DL, BD-RE
There is no need for game manager (multiMAN/IRIS/etc) or for webMAN/MOD when launching PS3 games from burned discs. The only requirement is that the disc is properly created (unencrypted, from proper ISO or from game folder using genps3iso) - the only check is that at sector 16 (0x10) offset 0x28 there must be a "PS3VOLUME" string.
If anyone wants to test it only on @smhabib's cex cfw 4.81 v1.02 cobra 7.5 (replace stage2.bin in /dev_blind/sys): cobra_stage2_cex_cfw_habib_481_v102_cobra750.zip
BD-R/RE discs are now much cheaper than 7 years ago, so this feature could be really useful for people who want to backup their collection on optical media and play it at any time without fiddling with usb drives, network streams or ftp.
Also it achieves 100% compatibility of all games released to date.
Update: @Joonie has been updating the GIT with Cobra 7.51 binaries (payload) and source code which can be found below:

Cobra 7.50:
- modules can be updated, no more hash update needed
- PS2 iso decrypted config support
- allow PS2 netemu on bc with cobra opcode 0x1ee9
- stealth extension now disables sc15 as well
- PS2 netemuu on bc and semi-bc PS3:
Code:
bc_to_net (opcode, param)
param=1 enable patch
param=0 disable patch
param=2 return current status
returns:
return 1=enabled patch

Update: @Joonie has been updating the GIT with Cobra 7.51 binaries (payload) and source code which can be found below:
From the README.md: COBRA 7.51 Source
[Supported CFW]
As of Feburary 2nd 2017, following has been changed and updated since 4.46 COBRA 7
[ Joonie's Changes ]
- Firmware spoofing is disabled due to the changes of PSN Auth since 4.60
- PLS3 patches are removed from modulespatch.c since this is one of those pre-applied patches on 4.xx CFW
- unknown E3 patches are removed to fix an issue with XMB, [Originally found by rancid-0, from his PS3ITA 4.50 COBRA]
- Dual VSH supported for REBUG REX / D-REX CFW, with the proper hash check code was developed by habib and Nzv recently.
- NPDRM Fself fix is no longer used due to improved fself patches hard coded within the firmware modules on REX/D-REX
- TMAPI can now attach any module [Thanks to aerosoul who reversed this!]
- Improved Stage0 Base payload, this clears stage1 when stage2 is not loaded on LV2, which completely disabled COBRA mode.
- Syscall 11 is added to support full lv1 peek.
- Syscall 15 is added to allow execution of any lv2 internal function.
- Allow Syscall 11 to gain full access to syscall 6/7/9/10 to prevent modification from homebrews like multiMAN.
- PS2 Launcher is no longer needed due to new codes in storage_ext, now COBRA can behave the same way that VSH does to apply configuration of DS3 controllers.
- PS2 Launcher can still be used, which allows PS2ISO with netemu on backward compatible consoles.
- PS2 Netemu toggle is added for Backward compatible consoles, it is very useful for those units with broken EE/GS chips as well.
- PS2 Netemu can now use decrypted CONFIG, place the game config file in the same game path for ex)
dev_hdd0/PS2ISO/GOW.ISO.CONFIG
- HASH calculation algorithm is changed, now it uses static hashes, so the hashes will not be changed unless modules have major changes.
- Stealth extension support to disable Syscall 15
- webMAN integration on boot. Also disables external webMAN plugin located in dev_hdd0
- PSN Patch stealth mode, it remove custom syscall from the ps3
- Improved map_path, to fix the issue with games like Shadow of Mordor
- Permission protection is disabled to increase game compatiblity and full DEX support.[no more issue with Target Manager or CCAPI]
- 80010017 / 8001002B Error fix is added since 4.60, this was developed to prevent issues with games when game disc is inserted in BD Drive.
- LIC.DAT check is patched to fix the issue with launching homebrew since 4.60
- Full burned optical media support for PS3 Games. (CD-R, DVD-R SL/DL, BD-R SL/DL, BD-RE)
- PS3MAPI 1.2.2 support, it is similar feature comparing to CCAPI, but open sourced project and also can unload vsh plugins , attatch process on all type of EBOOT.
- One of those great debugging features.
- Partial disable syscall8 and unhooks all cobra hooks (Part of PS3MAPI)
- Block update from disc
- Improved PSX media type support, now it supports following disc types
- 2048 // 2352 // 2336 // 2448 *
- Improved Video mode patch with proper region detection
- Original COBRA payload was relying on ps1emu's detection method, now COBRA has extra pre-processing that can detect region properly and force apply correct refresh rate depending on the game's region.
- (Improved PS3MAPI functions)
- Added PEEK/POKE (LV1/LV2) as PS3MAPI opcodes (syscall8)
- Added option to block access and request access to syscall8 using a key (also as PS3MAPI opcodes)
- Added temporary disablement of Cobra syscall8 to allow dumpers peek 0x1000 to 0x9800
- BASIC_PLUGIN hash is commented.
