Isn't there a clone of the machine in this video (https://www.youtube.com/watch?v=zrVSRIbBsvQ) It says Real arcade hardware recorded using the Elgato Camlink 4K and the OSSC. in the video description, meaning that there is no emulation involved. The video was captured from the real arcade machine -...

Of course, that doesn't explain why '-verify' and starting the actual emulation produce different results for you; you would expect them to have the same result. Yes, I would expect that as well, seems a bit weird. Maybe -verifyroms just checks for filenames and not for sizes and checksums? //EDIT:...

Thanks, I wasn't aware that there were significant changes in the different chdman versions (respectively their outputs), I assumed that was only the case for the ones with a CHD version change, so that 0.146 to 0.239 would produce the exact same output. I ran some code to run chdman for a load of v...

Hi, I'm somewhat confused about the SHA1 checksums of softwarelist CHDs, they don't seem to match, respectively I don't seem to be able to generate a CHD with a matching SHA1 from a CD image. For example let's take a look at https://raw.githubusercontent.com/mamedev/mame/master/hash/segacd.xml <soft...

Hi, I'm currently trying to fully understand how CHD files and their respective versions work and how to verify and convert them correctly. I have two different versions of area51.chd : One from a 0.78 reference set (CHD v3), one from 0.161 (CHD v5). If I look at those two with chdman 0.199 I get th...
