Re: DRAW CALL debugging.

So would I just find and hook into a general CPU memory write function and go "if(inside VRAM range)run_hook()"? You don't need to check "if inside VRAM range" - Dosbox does it for you. Look at vga_memory.cpp VGA_SetupHandlers function. There are already several page handlers (set up using MEM_ …

Re: DRAW CALL debugging.

First of all, get this ready-made tool called Bitmap Memory Debugger: http://www.theycamefromhollywood.com/bmd/ You will be able to examine Dosbox's memory visually.

Re: How to slow down real-time

in PC Emulation
I actually made such a version of Dosbox that allows adjusting the emulated video refresh rate, which works for speeding up and slowing down many games. http://www.vogons.org/viewtopic.php?p=326732#p326732 I might have had a version where refresh rate could be adjusted on the fly with some keyboard …
