Closed Sterophonick closed 3 years ago

Sterophonick commented 5 years ago

This version of MAME is unable to launch MESS systems that don't have a software list. Those systems include, but are not limited to: The Tiger Electronics handheld games Game & Watch Coleco Tabletop Tamagotchi Konami Handhelds

Please devise of a way to allow these games to be launched on this version.

gnw_mario

trying to launch these games using retroarch's frontend crashes retroarch for some reason, I would extend the XaviX/Sunplus games here too.

But it appear you have to have core option "mame_boot_from_cli" enable , option that i always had enabled so i didn"t notice the failure when disabled!

the problem is in execute_game(char* path) func that don't handle properly thoose systems. (if the system is not an arcade and dont have a software list). it act like adding such options -rompath path path/gnw_mario.zip gnw_mario

and then end up with something like 

Error: unknown option: gnw_mario

instead of doing

-rompath path gnw_mario

BTW the func static int execute_game_cmd(char* path) handle thoose systems correctly that why they boot fine using core option "mame_boot_from_cli" enable.

so temporaly fix is to enable "mame_boot_from_cli" core option.
