The boot.elf from 27 October merge with freedvdboot VTS_02_0.IFO play, but the latest boot.elf merge with the same again not working only a flicker and after a black screen, the October boot.elf stop at sector 00069AD0 but the new stop at 00069B30

@skelletR if you run new wle.elf from usb, does it black screen too?

No, I run the freedvdboot with October boot.elf merge, after go to USB and run the latest boot.elf and is open all good, only if merge the new with freedvdboot

Then, it is not actually a wle issue, but a FreeDVDBoot issue. Moving there>

According to this you need a specially prepared elf file for injecting.

so it requires that the ELF you load doesn't overwrite those functions I use (those are around 0x84000 - 0x85fff and 0x250000 - 0x29ffff)

You can run readelf -l to verify your executable satisfies this requirement. For example, this Tetris homebrew just uses 0x00100000 - 0x0017a940:

Yeah, this guide this I use, for that say the October boot.elf stop at sector 00069AD0 but the new stop at 00069B30

In the guide is said that not all elf files are accepted. I pointed to necessary elf requirements. This is not wlaunchelf fault, but freedvdboot fault, feedvdboot should be modified to accept specific elf.
