@Rockman98, i have a report that both games of Phantasy Universe works fine in the internal HDD
without Modes.
You are using the original IDE network adapter with an IDE HDD?
Or you are using one of those crapy SATA clone network adapters like the GameStar one with a SATA HDD?
Best regards.
EDIT: I tested myself both games:
Phantasy Star Universe (USA) (SLUS-21194)
Phantasy Star Universe - Ambition of the Illuminus (USA) (SLUS-21631)
Both games works perfect with OPL v1.0.0 and without any Modes.
Tested with the original IDE network adapter and IDE HDD.
The author of that thread and those who claim that the game does not work or needs Mode 8 with the internal HDD, it will be because they use clone network adapters and not the original adapter. These two games have always worked well on any version of the OPL on the internal HDD.
Reports made with clone network adapters should never be accepted.
It is well know that they have less compatibility and have strange behaviors
compared with the original one, they are trash.
EDIT 2: Tested also the PAL versions:
Phantasy Star Universe (PAL) (SLES-54308)
Phantasy Star Universe - Ambition of the Illuminus (PAL) (SLES-54892)
Ant they work fine also with OPL v1.0.0 in the internal HDD with the original network adaptader an IDE HDD.
No any Modes required.
Best regards
