MS-DOS Player v2/19/2024 - Released

Details: Category: Windows; Published: 18 February 2024

What's New:

Google Translate:

- When using strcpy_s(), when a string longer than the specified buffer length is specified as the copy source, exception 0xc0000417 may occur.
- For INT 67h, AX=5B00h/5B01h/5B04h, an error is now returned when a value other than 00h is specified for BH.
- Added support for MDA (Monochrome Display Adopter).
- Instead, the conventional memory limit has gone from B8000h to B0000h, a decrease of 32KB. (Still, it is 64KB larger than the normal environment due to the lack of VGA VRAM.) I also made the CRTC and Status Register accessible using the MDA address, and set the synchronization signal to 50Hz.
