Help with invoking retroarch in batch in windows from a front end

I’m using a front end (retrace) to launch retroarch.

It works fine with SNES and Atari 2600, but I can’t get it to work for N64 and NES.

Here is the syntax I’m trying. All the dll’s are in the core directory.

retroarch.exe" -L “cores\snes9x2010_libretro.dll” rom.zip (this works)

retroarch.exe -L “cores\nestopia_libretro.dll” rom.zip -> N64 and NES- this does not work

How can I see log files to see errors?

Can anyone help?

New documentation on Generating logs is here

Hi, I don’t use Nestopia for N64 and NES emulation, but I also start all my retrogames using batch files.

For N64 I use:

-L cores\parallel_n64_libretro.dll game.z64

For NES I use:

-L cores\mesen_libretro.dll game.nes

As far as I know, Nestopia doesn’t support zipped rom files. Have you tried using “rom.nes” instead of “rom.zip”? Also: is “disksys.rom” in your system\ folder (I think nestopia needs it) and is your batch file able to find the path to the system folder? Just guessing …

You are correct with Nestopia not accepting .zip and bios details

See the core info here https://github.com/libretro/libretro-super/blob/master/dist/info/nestopia_libretro.info

Or Load the core and go to Main Menu > Information > Core Information

Awesome using your cores worked :slight_smile:
