yes, I am well aware and VERY appreciative of Vas finally doing that but as he has told me himself this is simply a skeleton driver done off of schematics and was done in hopes really that others may take it on. I also would like to say I appreciate that Matt Ownby (Whom I consider the most knowledgeable person on the planet about the hardware) helped Vas providing him with dumps of previously undumped chips. As far as I know that was the first time Matt has contributed to MAME, I could be wrong? Anyway, YES I love that there is finally a STARRIDER driver in MAME but Vas did it to try and start something. It's been some time now and nobody has touched it. :/
