Problem to launch TRS-80 Model I games with MAME

[Sebiohazard]

Good morning all !

I have a problem with the launch of games TRS-80 Model 1 level 2 with MAME (trs80l2.zip) ... after loading a game in the player (see image) I restart the emulator but it does not nothing happens why ?

Normally the games are on autoboot floppy disks, with the SDLTRS emulator it works fine at restart ?! How to run the games, there is a command line to run ?

Thanks best regards !
