Summary	03530: Many games in igs_m027.c and pgm.c: MAME crashes after game info screen.
Description	When running the game ddp2, MAME crashes after the game info screen. E:\Emulateurs\Mame>mame ddp2 ddp2_igs027a.bin NOT FOUND (NO GOOD DUMP KNOWN) WARNING: the game might not run correctly. ARM7: Unhandled coprocessor 13 The game is marked as not working, but with others not working games MAME don't crash, and MAME don't boot if roms are missing, so it is not because ddp2_igs027a.bin is missing (romset is best aviable, not bad). The problem seems comming from the ARM7, but others games like Ikaruga have an ARM7 to emulate and works.
Steps To Reproduce	Type : mame ddp2, OK at the message "game not working", any key at game information, and voila.
Additional Information	Tested in both 32-bits and 64-bits builds of mame. Sets which error out include: bigd2 ddp2 ddp2a dmnfrnt dmnfrnta klxyj kov kov115 kov2p kov2p205 kovj kovplus kovplusa kovshp lhzb3 lhzb4 mgfx oldsplus puzlstar puzzli2 sddz sdwx svg theglad theglada

No.05152 Tafoid Administrator Nov 10, 2009, 17:53	I'm going to set this up as a catch all for the "ARM7: Unhandled coprocessor 13" errors so reports like this are not repeated.
