Razoola took over Kawaks so many years ago. The owner of Kawaks is no longer around. Rename to WinKawaks. He had to hack it in order to add the new drivers and changes.
Just like the owner of Final Burn quit and the new people took over. Made the changes, rebuild and rename it to Final Burn Alpha.
I have to say that Final Burn Alpha is better than WinKawaks. MAME is better out of all.
You probably Kawaks fan boy. I'm the MAME fan boy. MAME have HLSL and GLSL that will blows the rest away. MAME will continue on the changes.
By the way. I love the MAME Dev Team. Like a family.
Oh another thing is that WinKawaks will never change. Still the same old Kawaks. It need to be rebuild from the ground and up without any hacks.
