06765 Crash/Freeze Critical (emulation) Always 29 days ago 6 days ago

Summary 06765: tranqgun: Resets or Crashes on Game Over or if you pass Round 3 - No dipswitches
Description The dipswitches do not work..
Cocktail mode is stuck on permanently.
Doing save states during a certain time resets the emulator, ie while truck bonus is adding up.
Game crashes to Game Over after Round 3 complete. Tranquilize all 4 animals on screen at once.
During some game overs the screen freezes does not go to attract but you can get around it by putting credits.
Steps To Reproduce Here's something that most people have probably not tried. Your jeep only has 30 lites of gas. To get 10 more liters of gas you must tranquilize and drag 1 of each species to the jeep (4). This works

To pass a round in Tranquilizer Gun, tranquilize all 4 animals on the screen at once to go to the next level (monkey, lion, elephant, and snake). The game crashes with Game Over if you do this on round 3. (The only way to advance levels)

The only known other working version of the game is a Playstation 2 version on the Sega Ages collection where I had played and verified it and made it to round 5. I also tried using a super old version of mame from the early 2000s the problem is still there. (.36)

I have some more information about this bug now that the new version of MAME is out. It looks like the game is definitely having trouble trying to save any score data to any of the three high score slots at the top of the screen after the last life is lost. (Before GAME OVER is displayed). This appears to be where the crash happens.

I'm currently working on the vicdual driver, so I'll take a look at this soon.

Just so it doesn't get lost, here's a pic of the dip-switch settings provided by gregf: http://www.mameworld.info/ubbthreads/download.php?Number=371809
