info	0.115u3 [David Haywood] WIP: 0.125u7: Couriersud fixed duplicated inputs. 0.122u6: David Haywood removed speedups in the G-Stream driver which were breaking the game. 0.121u1: Aaron Giles optimized the hyperstone core, gaining ~50% speed improvement in most games. Implemented clock prescaling and corrected interrupt priority handling. Then fixed the clock speeds on the most of the games and killed most of the speed gains in quite a number of them (Sorry!). Changed E1-32XT CPU1 clock speed from 16MHz to 64MHz. 0.119u3: G-Stream driver update [Pierpaolo Prazzoli]: Changed to use a default NVRAM handler. Checked the inputs. Aligned the sprites. Added some comments about oki banking. Fixed sound1 rom loading. Removed 'Unknown' dipswitches. 0.115u3: David Haywood added G-Stream G2020 (Oriental Soft Japan 2002). 28th May 2007: David Haywood - G-Stream G2020 Part 2 at 4:37 PM: The video should now be fully emulated, however, there are still problems with the sound (some sample banking is not understood yet) There also seems to be a general problem with the game speed, it runs at 100% speed, but seems to spend most of the time polling the sound status register causing the game to run very very slowly. Not sure why it's doing that yet because the sound status register seems to be acting as expected, could be related to the banking problem tho. Thanks to Tormod for the PCB of this one in any case. It should be supported in the next update for any side-by-side comparisons. As pretty as it looks it's just a very generic Raiden Fighters wannabe. 28th May 2007: David Haywood - 2:03 AM: Streaming... Streaming... Recommended Games (Terra Force): Xevious Vs.
