commodore c64 t64 files not playable

[mczerski]

Hi,

I cannot play games with .t64 extention using game.libretro.vice emulator (CoreELEC kodi 20.1-Nexus on Amlogic S903X3) (.d64 works without any issues). Relevant kodi logs while trying to launch the game:

     info <general>: AddOnLog: game.libretro.vice: AUTOSTART: Autodetecting image type of '/storage/.kodi/userdata/addon_data/plugin.program.iagl/game_cache/Planet Miners, The (USA).t64'.
    error <general>: AddOnLog: game.libretro.vice: Filesystem Image Probe: Import GCR: Unknown GCR image version 32.
     info <general>: AddOnLog: game.libretro.vice: Filesystem Image: Unknown disk image '/storage/.kodi/userdata/addon_data/plugin.program.iagl/game_cache/Planet Miners, The (USA).t64'.

     info <general>: AddOnLog: game.libretro.vice: AUTOSTART: Resetting the machine to autostart '*'

Is this problem with vice emulator (the docs says it handles t64 files) or IAGL addon launching it in wrong way ?
