When attempting to fix MAME roms, some fix OK but many don't with the error:

Unexpected error: value cannot be null. Parameter name: entry

See screenshot:

This error is not very self-explanatory - any help appreciated!

Hi. It would be helpful to upload the log file (you can find it in "C:\ProgramData\romcenter") so that Eric can take a look at it and explain what has happened. If you don't want to upload the whole log, just isolate the part that contains the error and post it here.

Thanks.

I have noticed that for all the ROMs where I get this error message, some of the files in the ROM say "bad name" under "info".

Here is the log file:

Any help much appreciated!

Hi.

You'll just have to be a little patient. This (development-wise) is a one-man-show and sometimes there may be periods were real-life makes it difficult to be as involved as you wish with some things. I'm sure Eric will take a look at this, it just may take a while...

Hi

Thank you for your post and sorry for late reply. I'm busy at the moment fixing some interface problems.
I will have a look to this error, probably a datafile problem.

Stay tuned, I may need your help for some files...

It seems the problem comes from your astrof.zip file. Could you post it ?
