clrmame Discussion / Re: Scanning for missing roms after converting to CHD?

I meant clrmampro told me, sorry. Ah yes the file extentions might be a problem here. Well, I guess that I'll just have to live with the fact that what I want is not possible right now.

Really? I tried that, but mame just told me that I had an "invalid set" and after the scan all roms were missing. Don't know what I did wrong...

Thanks for this answer. I understand that the dat file is the issue here. I just wish there was a way to let a rom manager scan for file names listed in the dat, and not the extra information, such as crc32/sha1, etc.

My scenario is the following:

1. I have an (incomplete) rom set.
2. I convert the rom set to CHD to save space and for easier handling.
3. I delete the original rom files
4. I want to be able to check for missing roms in the future, when the set is updated, so don't have to acquire the complete rom set again.

The reasons why I cannot use custom dat files for this are:
1. There are no custom dat files for self converted CHD sets.
2. Even if there were, the would be different for every user, since different users might use different levels of chd compression
3. I am not able to creat such dat files myself.

Thanks again for your answer =)

Thank you for you reply. I already expected the answer to be 'no'. I thought that maybe there was a hidden feature that lets me scan for existing rom files by file name. I'm sure the file names are still the same as in the .dat file, even after conversion to CHD.

clrmame Discussion / Scanning for missing roms after converting to CHD?

Hey everyone,

I usually convert my disc based roms, such as PSX or Dreamcast, to CHD in order to save space and also because a single .chd file is much easier to deal with than .cue with multiple .bin files.

Now I want to find out which roms I'm missing, however, I cannot get any rom manager working with my .chd collections. Clrmamepro says I don't have a valid set, which makes sense.

My question is whether it is at all possible to scan my collection for missing roms ect. even though I converted my sets to .chd.

Thanks for your help! =)
