I want to extend the int 33h handling within dosbox with some custom functions. So calling mov ah,99h int33h would be handled by my code, but normal mouse driver calls would still be handled by the existing mouse drive code.
A normal DOS-TSR would install itself into int 33h and call the previous installed handler afterwards.
Is this also possible when creating callbacks in Dosbox? I'm aware that I could also modify int33_handler from the DOS mouse driver, but I would prefer a cleaner solution that also works when the mouse driver is not loaded.
