PSP2PS3 .iso conversion to .pkg issues

Does Grandia 3 have issues on PS3?

I know it's an aging system. But this machine played Sonic Unleashed, Asura's Wrath, Ratchet & Clank A Crack In Time, and Katamari games all with no issue. The R&C was even just earlier this year. But I booted up the digital PS2 Classic for this game (legally purchased, not emulated except where supported directly by Sony) and 20 minutes in (mind you the first 10 was cut scenes) my PS3 suddenly gives the 3-beep warning and shuts down. I do have a hypothesis, but it's not something I'm sure of. The cutscenes going on as long as they do could be an issue, if they are straining the system. I do notice that when coming in and out of PS2 games, my system loses output for a second and turns off the controller (implying it's rebooting some things). I also see that it currently displays a HUD on top of the normal PS Button Menu that gives me CELL/RSX temps and FPS but mutes game audio (can still see game underneath). Obviously that extra hud wasn't there in OFW. Same HUD also says SLUS-21344 (I believe game ID), Config file revision: 16,040, build r17495-main-rel. This has me wondering if the CFW has overridden the regular PS2 processes for normal digital releases with its own emulation process. These are all just details and hypothesi. I do see temps climbing a bit (I'm rerunning the same scenario but I skipped the opening cutscenes). Currently CELL 65, RSX 59, FPS 30. So it does seem likely it was overheat and not hardware failure, as both are climbing to that 69 threshold. But I'm wondering if this is normal for this game and/or if there's anything I can do to mitigate the issue or resort to finding other methods to play this. PS3 CECH-2001A, 4.92 CEX Cobra 8.5

So I recently installed CFW on my slim and it's been smooth sailing getting .isos installed. I'm following the compatibility list and today I've been struggling to get the 2 Persona 2 PSP games to create a .pkg file. It seems like it has something to do with patch files (they are I believe the Japanese versions of the games with english PSX dubs. The game id's check out on CDRomance and these should be playable, but when I load them in PSP2PS3 to be processed I'm getting UMD errors:

For Persona 2 Innocent Sin I get:

-Detected non-zero disc:\PSP Game sysdir opnssmp.bin iso needs patching.
-Warning detected non ELF disc 0 PSP Game sysdir opnssmp.bin iso needs patching.

I click build and then it says an attempt will be made to patch...And finally...

-There was a problem signing the Eboot Bin. Prx signer:Elf is too big.

For Persona 2 Eternal Punishment

I get the same as above, but when I click on build the message is:

-There was a problem decrypting the eboot bin
PSPCipher by TPU & Liquidzigong invalidprx.

I found some suggestions to run UMD, open up the files and delete an update folder, then save as an uncompressed .iso-(which I did), but the last step of signing eboot: I do not see any option to do so in PSP2PS3 (either the older or newer version)-Read it was just an option to check off, but nada as far as I can see.

I tried extracting the eboot.bin, signing it with PSP2PS3's sign_eboot.bat, repacking it in UMD Generator and redownloading the new. iso-Didn't work and still getting the .elf file to big error.

Can anyone offer some guidance? Thanks in advance.
