@mediamogul i found proof of a sega playstation. 😄

N.A.R.E.K.96

@edmaul69
I renamed bioses as there but only black screen,I evan reinstalled retropie

edmaul69

@N.A.R.E.K.96 did you try both emulators?

N.A.R.E.K.96

@edmaul69
yes and md5 of my bios files for both emulators are correct so I can not understand why it is not working

@N.A.R.E.K.96 how are you putting the bios files on and where?

N.A.R.E.K.96

@edmaul69 I am putting them in bios folder and copy with USB Flash Drive and by the way PSX and GBA are working fine

@N.A.R.E.K.96 I hate to be a broken record, but it's a BIOS issue. I had the same problem. It's likely because there are three different regions with two emulators, and each game may require a specific combination of emulator and BIOS. Sega CD is tricky to get working, and each game requires different emulators to work.

it's possible the bios files didn't copy over. so to be sure, check with the file manager, or drop to a terminal (press F4) and type:

md5sum RetroPie/BIOS/bios_CD* RetroPie/BIOS/*cd1_*

it should read:

e66fa1dc5820d254611fdcdba0662372 RetroPie/BIOS/bios_CD_E.bin
bdeb4c47da613946d422d97d98b21cda RetroPie/BIOS/bios_CD_J.bin

It's worth noting that you would need all 6 bios files to ensure you are able to play a given ROM.

@Panther7 thanks for pointing that out, i wasn't even aware since i've only ever used the lr-genesis-plus-gx emulator for this system (and only for a handful of games, The Terminator being one of them). i have edited my post with this new information.

@N.A.R.E.K.96 also look into your .cue file, and be sure the file names are correct and proper case.
more general info about this can be found here: https://github.com/retropie/retropie-setup/wiki/PC-Engine#pc-engine-cd

short of all that, it might just be a bad cd dump. test with a different one if possible

@N-A-R-E-K-96 as @chipsnblip said open up your cue file. If your bin file is called DrAcUla.BiN you need to have it say that in the cue file. Linux is case sensitive so caps and lowercase are very important. Even on the file extension. It is common for the cue file inside to say .BIN AND the bin file is really .bin

@edmaul69 file name is Terminator, The (1994)(Virgin)(PAL)[!].cue is this wrong ?

@N.A.R.E.K.96 can you show exactly the name of the iso file. That is what has to match the inside of the cue file. If you are using an emulator on windows caps and lowercase wont matter. Linux it matters. If this all checks out, then the bios is where your problem is.

This line inside the parenthesis has to match the name of your iso file exactly. Any differences at all and it wont work. Plus make sure all of your .wav files get loaded onto the pi as well.

N.A.R.E.K.96

@edmaul69 Terminator, The (1994)(Virgin)(PAL)(Track 01 of 10)[!].iso is the name

edmaul69

@N.A.R.E.K.96 can you remove the first line of the cue file? The one that says catalog...

N.A.R.E.K.96

@edmaul69 OK

N.A.R.E.K.96

I conected my retropie sd card to pc with Ext2fsd app and go to home\pi\RetroPie\BIOS\and this is what inside of that folder was

where are my bioses ?

mediamogul

@N.A.R.E.K.96

Are you by chance running ROMs from an external USB using this method? If so, your BIOS files would have been moved to the USB drive at /retropie-mount/BIOS.

N.A.R.E.K.96

@mediamogul no,from sd card with retropie
