I got a freemcboot memory card for my PS2 and tried playing games off an usb. It works with ps2 ISOs with some settings tinkering but not with PS1 VCDs. I looked up on the Internet that it should be the vcd format and the games pop up in opl manager. But i don't know why they don't appear in the same menu. Can anyone help me with figuring out what i need to do?
