Hello, my Name's Stephane (aka: JAGO/FRANCE) Just registered this community but let's keep it straight. :D i'm actually "trying" reverse engineering (IDA PRO) a Taito TypeX game already hacked and running through standard hardware. Unfortunately there are some issues about lag input, but it's not currently my first objective. I'm trying to figure out the detailled game behavior for hint and speculated /very hided game features.. i found your post from google : http://www.assemblergames.com/forums/showpost.php?p=390498&postcount=36 where you're talking about Taito Type X SDK. I need to understand some statically linked library behavior. Could you help me to figure out some things, or how to obtain some material you are refering in your post ?
