Anyway I tried the bios of a 9K model on the pcsx2 emulator and it worked only that opl keeps loading . Also I tried the file that inside the folder where there is many files coz the file that generated output inside the custom just crashes the emulator .
Hey I would say thanks for this awesome stuff . But I don't know how to flash the bios with the tool you said. Now how do I flash the bios on my ps2 ?? and which hardware do I need to do it ?? . and thanks in advance
