you using .103. If you want you can try Advmame .106. It has an option in the CONFIG/INI/CFG/ADV forgot the extension to SKIP EVERYTHING. It even have option to SPEEDLOAD so no waiting on booting (like NEOGEO, DECO CASS, PACMAN garbage screen at first etc....).
But first read the DOC that came with .103. It might have the SKIP_DISCLAIMER, SKIP_GAMEINFO etc...mention above.
