Can anyone get the brand new Mr.Do ZX Spectrum game to run on the Pi 0?

Have you tried using fuse directly (not the Libretro core - lr-fuse) ?

I just tried the cloned image in the speccy and it worked!
The only difference is that it was a Sandisk Ultra 64gb SD card instead of an 8gb one.
How on earth could that be the case?!
Thanks for your help anyway!

@uncledisgusting I think there's some configuration you have on the 'faulty' image. You compare the log files on the 2 systems and see what's the difference - but you'll need a verbose log (enabled through the Runcommand launch menu) to see the details.

@mitu Hi. I've got an older Jessie-based system with lr-fuse installed. I suspect @uncledisgusting might be having a similar problem. It looks like lr-fuse is expecting to find a .sna file rather than a .tap file:

I've now tested with non-libretro fuse and zesarux and both of these seem to be looking for a .sna file. Fbzx doesn't give any error messages at all.

@spud11 I'm not sure it's the same problem - you're probably kicked back to the Emulationstation gamelist, @uncledisgusting reported it stops with the emulator loading scren. Your log file is missing the launch command - does it try to load a .sna file or the .tap file ?

[INFO] Loading content file: /home/pi/RetroPie/roms/zxspectrum/Mr. Do!.sna.

Try updating the lr-fuse Libretro core from source.

[spud11]

Thanks, @mitu. I'll have a look when I'm at home.

[spud11]

@mitu Hi. I wound up compiling lr-fuse from source via Retropie Setup and was happy to see that it worked. (Installing from Retropie Setup often doesn't work for me now because I'm still on Jessie).

However, despite the successful compiling, Mr Do! still doesn't work. Not sure what is going on there.

If your rom is really there, my guess is that it doesn't like its name, try renaming it to something simpler like mrdo.sna

[mitu]

@spud11 i still don't understand why it tries to load a .sna file - the file I tested was .tap file. Try @barbudreadmon's suggestion and rename the Rom.

[spud11]

@mitu and @barbudreadmon That does work, thank you. It now loads the game. I changed the name to mrdo.tap and it works. Changing the extension to .sna did not work.

I can't get any inputs to work at present, but I suspect that will be because I'm on Retroarch 1.7.5 rather than a more recent one, so will need to update Retroarch if I can.
