First, it sounds like your computer is running windows. Windows can only see the Boot folder because the retropie folder is formated ext3/ext4 and Windows has a hard time reading it(at least Windows 7 does). I can't help you much there. If you can find someone with a linux box you can take your sd card, put it in a reader and insert it into that box and you should be able to see the retropie folder as well.

You could download a raspian image to a separate sd card, boot up your pi with that and use your card reader to open the retropie folder on the RetroPie sd. First copy your new game roms onto the desktop of your new raspian bootup. Then plug in your RetroPie sd in your card reader and you should see the retropie folder. On your RetroPie sd you can mine down thru home, pi, RetroPie, roms and finally to the folder holding the roms for your games. Then you can drag-and-drop your new game roms into their proper place.

I hope this helps.

Best place to get the 3 games you need actual DVD's for is This Box set have them on ebay fairly cheap as well

Cool. Thanks for the replies. Doing the upgrade now, got my fingers crossed.

When I try to configure retroarch (trying different aproaches to solve the issue) I see this error message in the bottom left side of the screen:

"Xin-Mo Xin-Mo Dual Arcade (5824/1505) not configured"

thanks for the link !

Thanks for the tips! I want to make the portable console, so I need an small display (to thickness too).
First time I bought the car backup TFT display, but its not delivered, so I refunded and bought this with though it will be better.

To Adafruit things, Im from Slovakia where as student I cant buy things like Adafruit PiTFT, this display from Ali is for me alot expansive, so the PiTFT is insta killer.

Thanks guys for tips, I will try to found something useful :-)

Ha, now you are making me seriously doubt myself. I swear the .old files had a modified date of when the update took place. If I was imagining this (which it sounds like I was if the code is not set to do this), there is a chance I would have kept a remote copy due to previous tweaks to both files.

I'll just make a mental note to see what happens when I next upgrade, the .old files have been removed now.

Thanks again.

Mame4all-pi seems to have the best performance of them all but AdvanceMAME has support for more games. imame4all libretro can be compelling because it utilises RetroArch controller configurations.

so i guess with the pi1 you'll be wanting all the performance you can get, so go for mame4all-pi

@dankcushions said in how to create my own dat file for manage MAME ROMs?:

you need to use romlister. if you search for that you should find what you need.

Oh man! A big thank you for this recommendation!! The Romlister is very very usefull to deal with the mess of managing MAME ROMs!

if ethernet or wlan is available -> Yes
so this is a real nice way to speed up the boot process, if u don't need network availability on startup (e.g. boot from lan ...)

Thank you very much, GrethTom, F12 worked perfectly however no response from "Q".....

Yes, that was also one of the reasons why I didn't try any harder and also did the migration to Jessie in the same process...

I know the file can be overwritted, but i still using Retropie 2 , when i managed to update it (maybe in a few months) will be easier. (This is a college project so i dont want to broke it)
