* Initial plan * Add INT 70h RTC interrupt handler implementation Co-authored-by: maximilien-noal <[email protected]> * Add INT 70h test and update documentation Co-authored-by: maximilien-noal <[email protected]> * Refactor RtcInt70Handler to extend InterruptHandler base class Changed from implementing IInterruptHandler directly to extending InterruptHandler base class. This eliminates the need for custom WriteAssemblyInRam implementation since the base class provides the same functionality. The handler now uses the standard pattern with Run() method instead of custom callback registration. Co-authored-by: maximilien-noal <[email protected]> * Address code review comments on RtcInt70Handler - Fix timeout comparison: use < instead of <= to match IBM BIOS SUB/SBB/JNC logic - Fix documentation: clarify INT 4Ah callback is not implemented - Fix null pointer check: properly check for 0000:0000 using AND logic Co-authored-by: maximilien-noal <[email protected]> * Wire up RTC periodic interrupts to PicEventQueue for deterministic timing Instead of lazy evaluation on I/O access, RTC periodic interrupts now use the PIC event queue for deterministic CPU cycle-accurate scheduling. When periodic interrupts are enabled, events are scheduled via PicEventQueue. When disabled, pending events are cancelled. This ensures interrupts fire at predictable CPU cycle positions as demanded. Co-authored-by: maximilien-noal <[email protected]> * Simplify RTC interrupt handler to match DOSBox pattern Reverted PicEventQueue integration - RTC uses lazy evaluation on I/O access as before. Simplified HandlePeriodicInterrupt to match DOSBox logic more closely: - Use 997 microseconds decrement (DOSBox value) instead of 976 - Simplified conditional: if count > 997 then decrement, else complete - OR user flag with 0x80 instead of setting it (matches DOSBox mem_writeb pattern) - Reordered CompleteWait to match DOSBox sequence The interrupt handler itself is cleaner and follows the established DOSBox pattern while keeping the real BIOS behavior. Co-authored-by: maximilien-noal <[email protected]> * Address Copilot AI review comments - Simplified null pointer check to use SegmentedAddress.ZERO constant for better idiomatic code - Added bios_int70_wait.asm to Makefile SOURCES list so it compiles with 'make all' Co-authored-by: maximilien-noal <[email protected]> --------- Co-authored-by: copilot-swe-agent[bot] <[email protected]> Co-authored-by: maximilien-noal <[email protected]>

Co-authored-by: maximilien-noal <[email protected]> * Fix CodeQL warnings and code review issues 1. Removed virtual property access from DosDeviceHeader constructor - Moved NextDevicePointer initialization to call sites - Avoids virtual call in constructor (CodeQL warning) - Prevents accidental overwrite of valid pointer values 2. Fixed duplicate enum value in GenericIoctlCategory - Removed Printer enum value (was duplicate of CodePageSwitching at 0x05) - Per MS-DOS spec, printer uses category 0x05 (code page switching) 3. Explicitly initialize NextDevicePointer at all device creation sites: - CharacterDevice base constructor - NullDevice constructor - BlockDevice constructor - EMS and XMS device headers All tests pass (681 passed, 1 skipped, 0 failed) Co-authored-by: maximilien-noal <[email protected]> --------- Co-authored-by: copilot-swe-agent[bot] <[email protected]> Co-authored-by: maximilien-noal <[email protected]>

* Initial plan * Fix DOS environment block to preserve full program path The environment block now correctly preserves the full directory path of the executing program (e.g., "C:\GAMES\MYGAME.EXE" instead of just "C:\MYGAME.EXE"). This fix addresses the issue where VB3 compiled DOS programs couldn't find their runtime. The runtime is typically embedded within the executable and the program determines its location by reading the program path from the environment block (after the double-null terminated variables, followed by a WORD count and the ASCIZ path). Changes: - DosFileManager.GetDosProgramPath: Now properly converts host paths to full DOS paths by finding the matching mounted drive and constructing the correct path including subdirectories - DosProcessManager.CreateEnvironmentBlock: No longer redundantly calls GetDosProgramPath since the program path is already a valid DOS path - DosDriveManager: Added GetDrives() method to enumerate mounted drives - Added integration test to verify environment block contains valid program path Co-authored-by: maximilien-noal <[email protected]> * Address code review feedback - Move path normalization outside the foreach loop in GetDosProgramPath - Use OfType<VirtualDrive>() instead of Where().! for null filtering Co-authored-by: maximilien-noal <[email protected]> * Address code review: fix StartsWith false positive and use ConvertUtils - Fix StartsWith check to verify exact directory boundaries by checking if the next character is a separator (e.g., "/home/user/games" no longer matches "/home/user/gamesdir/file.exe") - Replace inefficient while loop with ConvertUtils.ToBackSlashPath and ConvertUtils.ToSlashPath which already handle double slashes properly - Consistent use of forward slashes internally for host path comparison Co-authored-by: maximilien-noal <[email protected]> * Remove fallback path behavior in GetDosProgramPath Remove the backward compatibility fallback that would use current drive and filename when no matching mounted drive was found. The old behavior was incorrect MS-DOS emulation anyway, so throw an exception instead.

Following the FreeDOS EMM386 formula: (physicalPages + 1) * 4, the correct value for 4 physical pages is 20 bytes, not the count of allocated pages.

TODO
still needs to fix INSECTS.EXE
still need to fix IOCTL
still need to fix 'EMS: Less than 2 Mb' warning (day of the tentacle)
still need to implement a small function for B.A.T. II
still need to implement a small PSP function (INT21H) for Alpha Waves (edit: done)
still need to fix the DOS console (INT21H function)
This is only a reference branch, do not merge !
Still this branch fixes (among other things) :
Each area should be put in a separate PR, triple checked, and put under tests.
This branch is only for reference, as games need a lot of fixes in a lot of areas together in order to work.
This PR also brings lots of ASM based integration tests
Does not fix (and I will most certainly let other people fix it) :
Mouse clicks not registering in Rules of engagement 2 (but it can be played via the keyboard)
Mouse drift in some games
Mouse being way too fast in Princess Maker 2
