Summary	02872: smgp, outrun: Multisession crash going from smgp to outrun
Description	MameUI crashes and baseline goes to a blank screen when you launch smgp and then choose to run outrun in the same session.
Steps To Reproduce	MameUI: 1. Launch Super Monaco GP 2. Quit 3. Launch Out Run 4. Crash Baseline: 1. mame64 smgp -v 2. tab menu, select new game 3. choose outrun 4. black screen
Additional Information	Doing it on baseline when you get the black screen you still have OSD control, F10 works for example.

No.03641 Tafoid Administrator Jan 24, 2009, 21:32	For what it's worth on my build I get a crash, normal command-line.
No.03645 Atari Ace Senior Tester Jan 25, 2009, 01:43	This is an order of initialization bug. segaic16_memory_mapper_init() expects fd1094_driver_init() to have already been called, but this isn't done here (or elsewhere for that matter). This is typically harmless it seems, except when the last driver had a 1094 key and the new driver does not. Moving the routines around fixes the problem, but the problem occurs elsewhere so I'll see if i can come up with a more robust fix. diff -Nru zzs0/src/mame/drivers/segaorun.c 0hack/src/mame/drivers/segaorun.c --- zzs0/src/mame/drivers/segaorun.c 2008-12-20 17:11:26.281250000 -0800 +++ 0hack/src/mame/drivers/segaorun.c 2009-01-24 17:11:48.890625000 -0800 @@ -148,12 +148,12 @@ segaic16_textram_0 = auto_malloc(0x01000); workram = auto_malloc(0x08000); - /* init the memory mapper / - segaic16_memory_mapper_init(cputag_get_cpu(machine, "main"), outrun_info, sound_data_w, NULL); - / init the FD1094 / fd1094_driver_init(machine, segaic16_memory_mapper_set_decrypted); + / init the memory mapper / + segaic16_memory_mapper_init(cputag_get_cpu(machine, "main"), outrun_info, sound_data_w, NULL); + / reset the custom handlers and other pointers */ custom_io_r = NULL; custom_io_w = NULL;
