I have noticed recently that upon closing, DOSBox-X crashes (even with the provided Win32 Binary Build). Doing some debugging on it, I have found that it is trying to deallocate memory for different lists that were never allocated (or not properly allocated) in the first place. I have found that …

ReactOS (extract jar file) boots in jDOSBox (attached picture below). However, DOSBox+enhancements (major emulation featured in DOSBox-x) results in this error when booting ReactOS: INT13: AH=41h, Function not supported 0x55aa for drive: 0x0. jdosbox_boot.JPG I looked at the JAR file there.

Thank you for this updated release! I noted the disabling of INT2h for booting into an OS and also the work on the psp/dta functions. I've also noted a ~5% speedup in DOS and Windows games, using (GL)Quake as a benchmark test. I believe this speedup occurred at the time of the memory leak patches. …

when the menu is disabled, no errors are detected, so, there's something wrong in the gui menu. OK, I figured it out: Remember when I said that whoever wrote the INT 33h emulation didn't know that mem_readb() could cause page faults? The Win32 GUI code also didn't know that apparently. The reason …

looks like for me your gui menu is quite buggy with NT since it still does that trap bsod when clicking to the menu or to the close button of DOSBox :( I'll look into that when I can. It's probably the same issue as DOSBox's "kill" switch triggering page faults in NT. Perhaps the popup menu reads …

Okay. another update. I fixed the aforementioned use-after-free bug and then went ahead and went through the code with Valgrind to look for other memory leaks and patch them up.

Ah... shit. Alright. The fact that the DOS kernel is clearing Drives[] even if the CD-ROM emulation or floppy emulation intends to use it means that I've now created a use-after-free bug and DOSBox will eventually crash when you swap CDs. Zeroing the array on free resolved the possibility of stale …
