Sega CD 32x setup

[maabus]

Can someone please help with setting up Sega CD 32x games in Retroarch. 

When I run Sega CD 32X games in Retroarch with the picodrive core Retroarch just crashes. 

I can run regular Sega CD games just fine, but all of the 32x versions crash. If I try running the games with the  genesis plus core, the game loads but I get the this game needs the 32x unit. I know the genesis plus core does not work with 32x... but my game is image should be working. 

 

Can anyone help me with getting the 32x versions to work, or is there a different core that can be used? 

 

Thanks,

Check you have the correct bios files for picodrive in retroarch's system folder.

https://docs.libretro.com/library/picodrive/

thats all there is to picodrive, its should just work after that, if you are still having issues with it, it could be bad game dumps.

 

just to add to the info the correct checksums for the bios files are as follows.

Thanks @MadK9

 

I have those bios.

 

if I don't have the bios i get the failed to load content error in Retroarch, but when i have the bios it just crashes. 

My games are "correct" according to the redump dat file, and are in bin/cue format. do you have any info on a good dump that i can use to compare my files? 

 

Picodrive does work with normal 32x games, and my cd games work in gen-plus core, but all of the CD based games crash the picodrive core.
