@mitu That worked thank you!

@mitu yes, thank you. I finally found a good romset.

@george-spiggott I didn't know there was a Libretro version of pcsx2. I'm using the standalone version downloaded from the "experimental" section of retropie setup. Works great on my Linux Mint box. Just doesn't have support for CHD files. I'll keep my eye out for an lr version.

@mitu Sorry about that. All of the urls where he talks about lossy chd he also use it to upload roms, so I didn't know how to refer to that person and the method he uses.

Anyway, I have edited the first post. Sorry again

@nes as with the roms you will need the right CHD-Version for this rom-set.
btw - Killer Instinct will not run good even with a overclocked Pi4, so you might be dissapointed.

@silverchairbg said in Reicast not loading CHD files:

We do not plan to support other formats at this time.

Neither chdman, nor flycast are developed or maintained by RetroPie. There's no 'plan' for them here - you either use them according to their feature set/limitations or not.

@sssetz Thanks for the updates! Any luck since? Also, you said in your last post someone confirming they had it working for their RPi. What version? 4 I assuming?

@Dezmancer See http://retropie.org.uk/forum/topic/2/forum-rules

We cant support 3rd party images. Ask the images author for help.

I was planning on doing the same converting them to

@krytern said in CHD games not working for Sega CD.:

Looks like it is a problem with the CHD file.

sounds like you may not have converted it properly.

I downloaded Sonic CD to test ...

Firstly, you need to use CDmage (V1.02.1) to convert the 35 *.bin file tracks of Sonic CD into a single *.bin before you can use CHDMAN

after that you will have just 2 files ..

Sonic CD (USA).cue
Sonic CD (USA).bin --------- which is 587,601KB in size

after running CHDMAN

Sonic CD (USA).chd --------- 329,386KB

which is approx 12MB larger than your 317MB file

Tested it with my setup, and it works fine

How does PSx-rearmed cope with multi-disc files as .chd?

@mitu
thanks a lot
will give it a try

@mitu I think it's from the limited specs of the Pi Zero. I was actually really surprised that both CD based systems even worked on a Pi Zero in the first place. Somebody told me that they tried CHD files for both emulators on a Pi Zero and the Sega CD didn't perform well. Essentially a CHD File is a modified 7zip archive, so I'm not really surprised. I will eventually test it myself and update this thread when I know.

@cjax08 from what I have found:
iso is larger than bin
bin is larger than chd

and chd is smaller than pbp format for a psx game though not by much

Probably the wrong versions of the chds or roms.
But anyhow: i dont think that the chd titles will run fast enough to be playable, they need much power which the Raspberry does not offer.
