Update runs near perfect on this build this is my fav baseball game of all time.. I first played it on the megadrive :) still love it funny megadrive version is not as hard..

Ps if the sfx goes off just pull the left trigger it will come back on kind of hack fix on the other builds the sfx stays off
Anyways correct sfx and 60fps :)

Fast note the over clock in the c68 is 15mhz from 12mhz and the timer and frame rendering have throttle to allow it so on a over clocked dreamcast you get the 240mhz it's not locked.. with this build so if you had a overclocked dreamcast this build should allow fullspeed on almost all games.. So this has throttle and if to slow it skips by 1 fps get's slower then 50fps it will skip 4.. really never runs slowe then 54fps and when it does that it's for 1 sec or less only on some games.. games that would really work better would be metal slug 1 and 2 on a overclocked dreamcast..

Can it work in the future with this bios?

In Dreamshell is it possible to restart these games with the common controller entry (A,B,X,Y+Start) ? I need to know this because for those who have Dreamcast with HDD have to power off the console every time to play another Neo-Geo game, and the function is essential in order to prevent damage the HDD
