Regarding LAA (found
HERE).
There are two versions of the LAA app now.
One for a .netFramework v3.5 and lower......."
laa_2_0_4.zip".
AND one for .netFramework v4.0 and higher......."
laa_2_0_4_NetFramework_4_5.zip", (the latest .netFramework v4.6xxxx is used on the Windows10 latest build).
So the first obvious questions are........ which .netFramework version do you have, and which version of LAA are you using?
Another obvious question is (well actually there's more):
Is LAA confirmed doing its magic on your sh4.exe file?
To check this, use the "Advanced" option under the "Mode" menu heading. You should see this page pop up:
Two things you need to check here.
Is the "Path" (highlighted in blue) correct to find your "sh4.exe" file?
Is the "True" statement listed under the LAA column for your game?
My other obvious questions are, what's your computer specs?
