Summary	09091: punchout, spnchout: Access Violation crash with numscreens 2 for ini file under bgfx video
Description	When trying to utilize two displays for the games Punch-Out!! and Super Punch-Out!!, creating the respective .ini file, specifying 'numscreens 2' results in an Access Violation crash. Delete the .ini file, or just remove the 'numscreens 2' line, both games run without issue.
Steps To Reproduce	Create a punchout.ini or spnchout.ini file and place the line numscreens 2. Run "mame punchout" (or "mame spnchout") MAME crashes with an Access Violation error: D:\MAME>mame punchout ----------------------------------------------------- Exception at EIP=00007ff6ad530a94 (bgfx::d3d11::RendererContextD3D11::init(bgfx::Init const&)+0x1224): ACCESS VIOLATION While attempting to read memory at 00007ff6b8574750 ----------------------------------------------------- RAX=0000000004000010 RBX=0000016e04dc1040 RCX=0000016e04dce3d8 RDX=0000000000000007 RSI=00000004b30f8b40 RDI=00007ff6b4574e70 RBP=00007ff6b45743a0 RSP=00000004b30f8a90 R8=ffffffffffffffe0 R9=0000016e04dce408 R10=baac1f10365eb170 R11=00000004b30f8a60 R12=00007ff6b4574740 R13=00000004b30f8b40 R14=0000016e04dc1040 R15=0000000000000001 ----------------------------------------------------- Stack crawl: 00000004b30f8f80: 00007ff6ad530a94 (luaopen_lfs+0x9b3314) 00000004b30f8fd0: 00007ff6ad528785 (luaopen_lfs+0x9ab005) 00000004b30f9120: 00007ff6ad07ba44 (luaopen_lfs+0x4fe2c4) 00000004b30f92e0: 00007ff6ad08ad96 (luaopen_lfs+0x50d616) 00000004b30f9340: 00007ff6ad08ae22 (luaopen_lfs+0x50d6a2) 00000004b30f93b0: 00007ff6ad08b4fd (luaopen_lfs+0x50dd7d) 00000004b30f9420: 00007ff6ad08b822 (luaopen_lfs+0x50e0a2) 00000004b30f9450: 00007ff6ad08c1c3 (luaopen_lfs+0x50ea43) 00000004b30f95a0: 00007ff6abebfc37 (renderer_bgfx::draw(int)+0x0647) 00000004b30f9600: 00007ff6a7f55973 (win_window_info::draw_video_contents(HDC__, bool)+0x0063) 00000004b30f9710: 00007ff6a7f5a166 (win_window_info::video_window_proc(HWND__, unsigned int, unsigned long long, long long)+0x0736) Remove the numscreens line or delete the ini file and the game runs fine under just one screen.

No.22870 Robbbert Moderator 16 days ago edited on: 16 days ago	Works for me - no crash. Using "auto" video on Windows 10. You haven't said what video setting you're using. Going by the dump it appears to be -video bgfx -bgfx_backend d3d11 I tried that and it still worked.
No.22871 trebor Tester 16 days ago edited on: 16 days ago	You actually nailed the cause for me. Starting with a clean/brand new install folder If I have this set in mame.ini... # OSD VIDEO OPTIONS # video auto The above with numscreens 2 enabled in punchout.ini file created runs fine. However... # OSD VIDEO OPTIONS # video bgfx The above with numscreens 2 enabled in punchout.ini file created crashes mame.
No.22872 trebor Tester 16 days ago	I updated the Report Summary to better reflect the issue.
No.22873 Robbbert Moderator 16 days ago	Have to wait for what other people say, since it works for me.
No.22882 Robbbert Moderator 14 days ago	Setting this to acknowledged, pending someone, anyone, able to confirm a crash.
No.22885 hap Developer 14 days ago	What about other 2-screen games? I don't have 2 monitors connected, so I can't try. Does it crash with this for you? (works ok here): mame punchout -view 6 -video bgfx -nowindow
No.22886 Robbbert Moderator 14 days ago	I don't have 2 monitors either, so it just gives 2 windows, one for each screen. You can move them around so you can see them both at the same time. I don't know what "view 6" does, but your test just showed the 2 screens one above the other.
No.22888 hap Developer 14 days ago	That was for trebor. As for view 6, that selects one screen, so I was wondering if punchout also crashes with a single screen on his pc (no -numscreens 2).
No.22907 ICEknight Tester 11 days ago edited on: 11 days ago	I have three screens connected and just checked. Having numscreens 2 in mame.ini also makes it crash for me right away (even before it shows MAME's initial menu): ----------------------------------------------------- Exception at

No.22908 ICEknight Tester 11 days ago edited on: 11 days ago	Strangely enough, if I'm quick with the mouse and click on MAME's taskbar icon before the crash, MAME's windows will be restored in time and the game will run properly. It looks like, for some reason, only the last monitor starts with MAME's window in full screen and the others have to be restored manually by clicking on any of their icons.
