Summary	09431: prosporta: Internal crash in attract mode after 95 seconds
Description	Game listed as working. After running in attract mode for a while, a tennis court shows, some music starts, then the music gets quieter, the screen fills with garbage and then freezes. MAME keeps running (no crash), but the game is no longer working. You can still insert coins and get a tone, but unable to start a game. The parent "prosport" has no problem.
Steps To Reproduce	>mame prosporta Press a key to skip the orange warning. Let it run for a while until the sound starts playing and watch. The error log is full of unmapped writes to main memory.

No.24308 Robbbert Moderator 2 hours ago	Thanks, no crash now. Noticed bad gfx, which also happens with "prosport", as if the gfx roms aren't loaded correctly. But maybe that's what the gfx flag is for.
