RPCS3
Debug Builds of Games with "liblv2dbg" Crash on launch/Debugging flag
Debug Builds of games like Need For Speed Rivals & LittleBigPlanet can be modified to boot on rpcs3, however they crash on as soon as they are booted. however i presume a certain flag in RPCS3 is missing that allows it to boot or not. This flag i assume is not defined which leads to rpcs3 crashing.
For Example in an E3 Debug Build of NFS Rivals or in earlier builds of LBP3, Booting Leads to a Memory Access violation. but has a warning that when looked into further reveals whats wrong.

What The Log is referring to: https://www.psdevwiki.com/ps3/Bootflag.dat
Essentially its a flag that sets liblvl2dbg as enabled or disabled. This is used for debug builds however final or close to final builds don't check it.

But the behavior in rpcs3 leads to a fatal error that crashes the emulator instead of process. Which doesn't occur on a real ps3.
Here is RPCS3.log and TTY.log that you requested, same game (Need for Speed Most Wanted 2012 debug E3), except with render set to null this time. (THIS TIME, I BOOTED IT AS IS, NO MODIFICATIONS IN ITS FOLDER) From TTY.log the game loads everything just fine except to the last point where it loads some ui music and stuff, and it just stops there. If I turn on renderer (OpenGL), the same lines (in yellow). Did RPCS3 run out of "CPU"? running the game reveals that all of my threads are used at 100% when the game starts. It should be a problem with RPCS3 (or hardware, if you will). RPCS3.log TTY.log Going to fully check that there are no software issues before going to upgrade my laptop. Thanks and take your time.

mmm, mind sharing where you got that prototype so i can test it
LoL I thought it was [email protected] Anyway I resent it to your other email, check it I am [email protected] I'm not active on Discord much btw.
ok so i have everything i need to test it more.
for this experiment i'll use LittleBigPlanet 3 Alpha (note: i changed the title id of LBP3 for ease but it doesn't really matter, the og title id was BCES01663) Also Replace the Alpha's files with these: https://www.mediafire.com/file/z4w1i1dxdf6vmfv/LBP3+Alpha+RPCS3+Files.rar

Before patching the eboot i get this:
E LDR: Invalid or unsupported file format: D:/Miscellenous/RPCS3_VHDD/dev_hdd0/game/ALPA01663/USRDIR/EBOOT.BIN
After using unfself and make_fself to patch the eboot to work with rpcs3 it does boot but fails with a file-system mounting error

However the tty is much more interesting:

Essentially we can avoid this by deleting wws_crashreport_uploader.self
see the bootflag for liblvl2dbg is set in both cex and dex according to the dev wiki but only libsysmodule.sprx has this flag on CEX.
Basically This executable was built with BUILD_MODE = 3 means that the game was compiled with the debug config.
RPCS3 behaves correctly when using CEX however it does not work correctly when using DEX firmwares. I assume because RPCS3 is HLE that this could be added to CEX. I'm Sorry If this was word salady but i can try to explain it more if you guys need specifics. A lot of these are assumptions from what i can gather.
After some research if /dev_hdd0/data/bootflag.dat is found, the game loads liblv2dbg_for_dex.sprx instead of liblv2dbg_for_cex.sprx, which is only found in debug firmware. So its an issue about unsupported debug firmwares.

could something like that be implemented on supported firmwares on rpcs3 for convenience?
is that still an issue? or an obsolete report that could be closed by main developers?
2 weeks and no reports back, should be closed and if discovered to still be an issue, be reopened and mentioned
