Hi,
i have a new installed version of retropie 3.4, but Megadrive won’t work for me.

Can you try renaming your rom without the #? To Jurassic Park.SMD, maybe. I renamed one of my roms to Batman # SMD.smd and picodrive wouldn’t load it.

I renamed it to Jurassic Park.SMD and it works !

So how can i solve my problem? my MegaDrive DB is huge and i worked on the xml file manually for weeks. Changing every file is no option for me.

On Retropie 2.6 it works with Jurassic Park # SMD.SMD.

You could try running a bash script to rename the roms. I don’t know how to do that myself but try google (http://bfy.tw/rVb)

Regards the gamelist.xml files, the simplest solution may be to insert your SD card into your desktop and use the search and replace function on a text editor.

Either way, make sure you back up your romset and gamelist.xml before you start. It may also be worthwhile trying your bash script on a subset of roms.

from terminal
```
cd [roms folder]
rename -n "s/#//g" *
```
remove -n to actually do the renaming.

rename -n "s/#//g" *

Can you please explain me this syntax? Just for a better understanding.

if i do this:
rename -n "s/#//g" *
all files are renamed like this:
Zool # SMD.SMD renamed as Zool SMD.SMD

but if i switch the directory and come back, all files are named like before “Zool # SMD.SMD”.
So the new names are not saved.

[/quote]

The -n part means “take no action” so it just shows what would happen.
When you want to run it, remove the -n option as buzz says.

The “s/#//g” part means
“substitute occurrences of the hash symbol with nothing, and the g means do this for every occurrence of the hash, so do it globally”

The * just means check all files.
