Hello!
i have a PS2 SCPH-50001 with a genuine NA with bitfunx SATA adapter,
a 500gb SATA HDD prepared with " HDDOSD_100J_ATADP_DTL-H_FIX_48BIT_APPS.IMG "
after boot uLaunchELF, navigating to hdd0:
i have some partitions
but only 2 intrestings
PP.ULE
PP.OPL
with kelftool was easy to update...
OPL-Launcher
OPL-Launcher reads hdd0:/__common/OPL/conf_hdd.cfg to launch $OPL/OPNPS2LD.ELF.
You can inject OPL-Launcher into APA using i.e HDL Dump:
hdl_dump.exe modify_header hdd<Disk Number>: <PP. Partition with PS2 game>
To do so, You must also prepare a few files for the injection...
