ok, so i have something working with a single batch file, but i have only tried it on a couple games.
i create an emulator called Daphne in LB.
i set this emulator to run my daphnebatch.bat with checkbox enabled for "don't use quotes" and "use filename only without file extension...". this gets you a good %1 value passed in so you can use just one batch file.
so what you import for a game is the game .txt files (liek lair.txt, lair2.txt, etc) inside your Daphne framefile folder and set the emulator to Daphne.
inside my batch file i just substitute what is needed, so only one simple batch file with one command line.
the daphnebatch.bat batch file i’m testing with as an example is just this:
daphne.exe %1 vldp -framefile framefile\%1.txt -blank_searches -min_seek_delay 1000 -seek_frames_per_ms 20 -homedir R:\Arcade\Daphne -nocrc -noissues -noserversend -sound_buffer 2048 -x 800 -y 600
i assume you can change the custom parameters and it would still work as long as those parameters work on all the games. i am not sure if any games have a specific parameter that doesn't work with the other games.
