Here is how mine is setup.
First, use the Teknoparrot GUI to add a game. This creates the game's XML file in the Teknoparrot\UserProfiles directory.
The just point your Attract Mode's rompath to that folder with xml as the rom extension.
# Generated by Attract-Mode Plus v3.0.0
#
executable $PROGDIR\..\Emulators\Teknoparrot\TeknoParrotUi.exe
args --profile=[name].xml
rompath $PROGDIR\..\Emulators\Teknoparrot\UserProfiles
workdir $PROGDIR\..\Emulators\Teknoparrot
romext .xml;<DIR>
system Teknoparrot
artwork boxart $PROGDIR\..\Emulators\Teknoparrot\roms\boxart
artwork cartart $PROGDIR\..\Emulators\Teknoparrot\roms\cartart
artwork flyer $PROGDIR\..\Emulators\Teknoparrot\roms\flyer
artwork marquee $PROGDIR\..\Emulators\Teknoparrot\roms\marquee
artwork snap $PROGDIR\..\Emulators\Teknoparrot\roms\snap
artwork wheel $PROGDIR\..\Emulators\Teknoparrot\roms\wheel
No BAT or LNK files needed this way.
