Hi,

i have bought a new USB 2.5" HDD which is USB 1.1 compatible for PS2. (FAT32 and 32KB cluster size, Primary)
The problem is the Device is ONLY found in UlaunchElf. I can even launch .ELF from USB HDD with UlaunchElf.
But when i'm in the ELF Program (PGEN, FCEUX, SNES9x) it does not find the HDD. And thats strange in my opinion.

I found out that there are USBMASS IRX files which work with newer HDDs and i tried several .IRX files
but all with the same result. One IRX file made UlaunchElf not find any mass: HDD.

What can i do to make the PS2 Programms find my HDD? Maybe a special USBMASS IRX?
