Summary	06302: cybsled: Crash after defeating Round 3 in Vs. Computer Combat
Description	The game crashes directly out of MAME to command-line after defeating Round 3 in game. I was able to build a debug version and got this backtrace on crash. warning: assert: ../../../../../src/emu/devfind.h:333: index < m_length Thread 1 received signal SIGTRAP, Trace/breakpoint trap. 0x7668338e in KERNELBASE!DebugBreak () from C:\Windows\syswow64\KernelBase.dll (gdb) bt #0 0x7668338e in KERNELBASE!DebugBreak () from C:\Windows\syswow64\KernelBase.dll #1 0x0339f8e1 in osd_break_into_debugger () at ../../../../../src/osd/modules/lib/osdlib_win32.cpp:232 #2 0x02f7aec8 in emu_fatalerror::emu_fatalerror () at ../../../../../src/emu/emucore.cpp:29 #3 0x00bfe2ab in region_ptr_finder<int, false>::operator[] () at ../../../../../src/emu/devfind.h:333 #4 namcos21_state::read_pointrom_data () at ../../../../../src/mame/drivers/namcos21.cpp:539 #5 namcos21_state::transfer_dsp_data () at ../../../../../src/mame/drivers/namcos21.cpp:675 #6 0x00bfe3b5 in namcos21_state::dspram16_w () at ../../../../../src/mame/drivers/namcos21.cpp:790 #7 0x03f975ff in delegate_base<void, address_space&, unsigned int, unsigned short, unsigned short>::operator() () at ../../../../../src/lib/util/delegate.h:514 #8 0x03cfd562 in handler_entry_write::write16 () at ../../../../../src/emu/emumem.cpp:453 #9 address_space_specific<unsigned short, (endianness_t)1, false>::write_native () at ../../../../../src/emu/emumem.cpp:1170 #10 address_space_specific<unsigned short, (endianness_t)1, false>::write_word () at ../../../../../src/emu/emumem.cpp:1455 #11 0x03c0011c in tms32025_device::M_WRTRAM () at ../../../../../src/devices/cpu/tms32025/tms32025.cpp:310 #12 0x0261e4ac in tms32025_device::PUTDATA () at ../../../../../src/devices/cpu/tms32025/tms32025.cpp:487 #13 tms32025_device::sacl () at ../../../../../src/devices/cpu/tms32025/tms32025.cpp:1289 #14 0x0261ffc6 in tms32025_device::execute_run () at ../../../../../src/devices/cpu/tms32025/tms32025.cpp:2068 #15 0x02ff75cc in device_execute_interface::run () at ../../../../../src/emu/diexec.h:191 #16 device_scheduler::timeslice () at ../../../../../src/emu/schedule.cpp:473 #17 0x02fc3338 in running_machine::run () at ../../../../../src/emu/machine.cpp:341 #18 0x01badcb5 in mame_machine_manager::execute () at ../../../../../src/frontend/mame/mame.cpp:226 #19 0x01c05585 in cli_frontend::execute () at ../../../../../src/frontend/mame/clifront.cpp:282 #20 0x01bacd74 in emulator_info::start_frontend () at ../../../../../src/frontend/mame/mame.cpp:325 #21 0x01b0c996 in utf8_main () at ../../../../../src/osd/windows/winmain.cpp:300 #22 0x0339c9d1 in wmain () at ../../../../../src/osd/windows/main.cpp:45 #23 0x004013f0 in __tmainCRTStartup () at C:/repo/mingw-w64-crt-git/src/mingw-w64/mingw-w64-crt/crt/crtexe.c:329 #24 0x7641338a in KERNEL32!BaseThreadInitThunk () from C:\Windows\syswow64\kernel32.dll #25 0x77829902 in ntdll!RtlInitializeExceptionChain () from C:\Windows\SysWOW64\ntdll.dll #26 0x778298d5 in ntdll!RtlInitializeExceptionChain () from C:\Windows\SysWOW64\ntdll.dll #27 0x00000000 in ??

No.21701 danylopez123 Tester Aug 16, 2023, 13:13	If i remember, i've found a way to dodge this crash, at least, with what i had using the first tank Madison Hawk: At Round 3, when you defeat the enemy, look away so the enemy Tank doesn't show on-screen and keep it like that, this will avoid the crash, same thing happens at Round 4, just do the same, look away, wait and done.
