Hm, so now that I am getting more serious about SHMUPs, I am wondering how much better the new CAVE driver might be. The existing one works well in that it runs games at 100% for me, but I am starting to realize that they run a bit "too" fast - the Arcade originals have slowdown when there is a lot of bullets on screen. So I am wondering if I should compile MAME .152 with the new cv1k.c driver diff or if it's best to just wait for .153 and hope they put it back in the official release (and hopefully address sound, etc) I saw Haze post somewhere saying that basically the new cv1k.c driver is has some speed issues because it's back on the path of accuracy rather than hacks. Hopefully it will now get refined into a good, accurate driver.
