Shield Portable Retroarch Mame Core a5200 via Mess Please Help

Hello all, I’ve been searching the forums and other places to help with this configuration problem but have been unsuccessful for a few hours.

I have a Nvidia Shield Portable running the latest (for it) Android 5.1 kernel 3.4.10-g3b0ee0f.

I have the latest (as of today) retroarch from the play store. I am trying to get the a5200 to work properly. I have my structure setup on internal storage (writeable): …/data/com.retroarch/system/mame/hash …/data/com.retroarch/system/mame/roms/a5200 …/data/com.retroarch/system/mame/roms/a5200/a5200.zip (5200.rom inside) …/data/com.retroarch/system/mame/roms/a5200/ballblze.zip (ballblze.bin inside)

I eventually turned on level 3 error logging. Here is the output:

I’m not a developer, so I’m not sure what’s going on here. Any help would be appreciated.

[QUOTE=basis;37693]Hello all, I’ve been searching the forums and other places to help with this configuration problem but have been unsuccessful for a few hours.

I have a Nvidia Shield Portable running the latest (for it) Android 5.1 kernel 3.4.10-g3b0ee0f.

I have the latest (as of today) retroarch from the play store. I am trying to get the a5200 to work properly. I have my structure setup on internal storage (writeable): …/data/com.retroarch/system/mame/hash …/data/com.retroarch/system/mame/roms/a5200 …/data/com.retroarch/system/mame/roms/a5200/a5200.zip (5200.rom inside) …/data/com.retroarch/system/mame/roms/a5200/ballblze.zip (ballblze.bin inside)

I eventually turned on level 3 error logging. Here is the output:

I’m not a developer, so I’m not sure what’s going on here. Any help would be appreciated.[/QUOTE]

Hi mate, Search Gavin Rae on YouTube, I did a video on this I’ve got about 50 systems running through MAME core in RetroArch Android, but don’t seem to get a reply when I ask anything on here!! In your logcat it’s a BIOS error, make sure your BIOS is zipped and unzipped :slight_smile:

try:

roms/a5200.zip roms/a5200/a5200/a5200.zip

It’s weird it doesn’t behave like on windows, I have a few ideas to fix it but working on mame is boring/tiring.

Great - thanks guys, I’m able to get it working now!
