No.09598 etabeta Developer Jun 12, 2013, 07:59 edited on: Jun 12, 2013, 08:00	these are two separate issue. I can reproduce the former and it seems due to command line handling being unable to add automagically the cdsys cart with current code. in a sense, it's accurate to the system (which would not have worked without the cd cart inserted), but it's still a bug because we are supposed to force the cart loading... I cannot reproduce the crash on the other hand. does it work if you run "mess64 pce -cart scdsys -cdrm draculax" (which for the record would be the correct syntax from command line ;) )? or does it crash in that case too? depending on the answer I might have an idea about what the problem could be...
No.09599 LordFlux Tester Jun 12, 2013, 09:00	when using: mess64 pce -cart scdsys -cdrm draculax MESS loads scdsys correctly. When I press Run to start the game, MESS crashes and displays the following: 00000f32 00000002 00000f34 00000001 00000f75 0000000a ----------------------------------------------------- Exception at EIP=00000000007B30FC (not found): ACCESS VIOLATION While attempting to write memory at 0000000008578B60 ----------------------------------------------------- RAX=00000000084A6B60 RBX=00000000035149E0 RCX=000000000351D5A0 RDX=000000000792B860 RSI=0000000003514E40 RDI=0000000003514E40 RBP=0000000000238820 RSP=0000000000238820 R8=00000000000D2000 R9=000000000000004C R10=000000000351C640 R11=0000000000000001 R12=0000000000000001 R13=0D075737546939E4 R14=0DE0B6B3A763FFFF R15=F21F494C589C0000 ----------------------------------------------------- Stack crawl: 0000000000238820: 00000000007B30FC (not found) 0000000000238860: 0000000001D55333 (not found) 00000000002388A0: 0000000000F95CEC (not found) 0000000000238960: 000000000138DDD0 (not found) 0000000000238B50: 00000000013A44F4 (not found) 000000000023F350: 00000000012E2D1D (not found) 000000000023F890: 0000000001449B63 (not found) 000000000023FE00: 0000000000CA6124 (not found) 000000000023FE60: 000000000175D59C (not found) 000000000023FF20: 00000000004013F0 (not found) 000000000023FF50: 00000000004014F8 (not found) 000000000023FF80: 000007F8BB02167E (BaseThreadInitThunk+0x001a) 000000000023FFD0: 000007F8BD8CD609 (RtlUserThreadStart+0x0021)
No.09600 LordFlux Tester Jun 12, 2013, 09:12	I just tried several other CD games using the corrected syntax and it looks like some games work and others don't. One interesting case in particular is: mess64 pce -cart scdsys -cdrm cotton The game starts and tells me that the File Cabinet is not initialized. When I press Run to start the game, then it crashes. Maybe the crash is NVRAM related?
No.09601 LordFlux Tester Jun 12, 2013, 09:44	I believe I found the cause of the crash. When I reported the bug, I didn't think about the fact that I had 'window 1' set in my MESS.INI file. When I change it back to 'window 0' then draculax works. Now when I run: mess64 pce -cart scdsys -cdrm draculax -window The game crashes after pressing Run. It works fine in full screen mode.
No.09602 etabeta Developer Jun 12, 2013, 10:00	that's even weirder than I would have expected... are you in a position to compile the source? it would help a lot if you could get a build with SYMBOLS=1 and obtain a full backtrace
No.09604 etabeta Developer Jun 12, 2013, 12:15 edited on: Jun 12, 2013, 12:15	OK. with some help from Tafoid, I was able to spot a bug in the RAM handling for SuperCDSys cart (and for Populous too). The crash problem should be fixed in current svn.
No.09606 etabeta Developer Jun 13, 2013, 06:58	only half of the reported issues has been fixed by my change... the bug about "mess pce -cdrm draculax" not working has not been fixed and it's due to an issue in the automount code from softlist
No.09607 Tafoid Administrator Jun 13, 2013, 12:18	I had no idea of any automount code. That just sounds like someone being lazy. You'd have to mount the card manually for CD's anyway. I took this bug, anyway, as the CDROM's not working issue due to the RAM handling. If the other issue needs a report (which I don't think it does), then so be it.
No.09609 etabeta Developer Jun 13, 2013, 21:02	No lazyness involved. ;) Some releases ago (at least 1 year has passed, maybe more), Micko explicitly added to softlists the capability for MESS to be aware that a specific item require another item to be loaded See lines <sharedfeat name="requirement" value="cdsys"/> and <sharedfeat name="requirement" value="scdsys"/> in hash/pcecd.xml This broke in latest release, because Micko's code seems to take precedence over the slot option setup, causing the cart not to be properly initialized. it's a bug :)
