Okay, since I'm an idiot, the folowing rips weren't using DSP at all (stupid Koei using more than one mixer)

Angelique Special (1996)(Koei)
Nobunaga's Ambition - Tenshouki with Power Up Kit (1997)(Koei)
Sangokushi Koumeiden (1997)(Koei)

Please redownload for 100% more reverb/echo.

Also, one new rip:

Romance of the Three Kingdoms 5 [Sangokushi V] (1996)(Koei)
