Install PCE-CD roms

Hello Anyone knows how can I play to PCE-CD roms on retroarch 1.3?

Thanks

The CD-Rom Bios has to be named syscard3.pce and put in the retroarch system folder.

And the roms have to be in .iso format?

I have found USA and JAPAN bios. I have to rename them?

the roms need to be bin/cue images

Once I have the rom on bin/cue format, how can I play? I have just rename Usa bios to syscard3.pce and I put on system folder. Am I on a right way? What about japan bios?

I use [BIOS] Super CD-ROM System (Japan) (v3.0) usually. I think it works for both region.

Then you do load content->load and detect core-> select your cue file-> select Mednafen PCE Fast core.

It works but when I want to play, appears a message to cancel, format or cancel ram. I have chosen cancel and when I want to play, appears “load error”. How can I reset the ram of the game?
