I imagined a trick that maybe works, i never tryed it though, but i think worths to be mentioned because it allows to "fix" games on the PS3 (without need for any PC or PC app)I had the same problem with some games, they stayed on black screen, I did everything and for me the solution was that I had to resign the game's eboot to 3.55 so that they work in HEN, I used "ESSSE RESIGNER v4.5.4" to resign them to 3.55 (NOT ODE OPTION)
What you need to do is to modify the value of PS3_SYSTEM_VER inside the PARAM.SFO to a version higher than your actual installed firmware... lets say.... to 9.99
Then try to boot the game in a backup manager and the backup manager is going to "autofix" the executable files (EBOOT.BIN, SELF, SPRX) with the keys of an older firmware (either 3.40 or 3.55 or something like that)
And also is going to modify the value of PS3_SYSTEM_VER inside the PARAM.SFO to the same old version
Is better to dont modify any game file though, this kind of fixes was required if the game request a version higher than the one you already have installed
*IrisMan have a hexadecimal editor inside the filemanager.... it allows to modify the PARAM.SFO file in the PS3
