Gyruss (Konami)

0.29 [Nicola Salmoria]

0.20 [Mirko Buffoni, Michael Cuddy, Nicola Salmoria]


- 0.111u5: Buddabing added save state support to Gyruss.

- 0.94u2: Nicola Salmoria rebalanced Gyruss volume.

- 0.93u1: Nicola Salmoria rebalanced Gyruss sound.

- 0.93: Added audio RC_Filter.

- 0.37b12: Added M6809 (2MHz) CPU2 and fixed CPU2/3/4 roms addresses.

- 21st January 2001: Nicola Salmoria added accurate sprite multiplexing emulation to Time Pilot and Gyruss. Gyruss with also emulating the slave 6809.

- 0.34b3: Francesco Caporali added RC filter emulation to Gyruss. This improves some sound effects, e.g. the force field noise.

- 0.34b2: Nicola Salmoria added clone Venus (bootleg 1983).

- 0.30: Nicola Salmoria added full emulated sound in Gyruss. You can remove all the samples, they are no longer needed. Also, music tempo should now be correct. Tatsuyuki Satoh, Fabrice Frances, Nicola and Pete Ground completely rewritten the 8910 emulator and interface. This affects a lot of games, but the one which benefits more is Gyruss: it now plays many sound effects which were missing.

- 0.29: Nicola Salmoria added Gyruss (Konami). Renamed (gyruss) to (gyrussce). Nicola Salmoria fixed sprite/character priority in Gyruss. Accurate colors in Gyruss.

- 0.27: Nicola changed the 8910 sound chip emulation interface to allow updates more frequent than 60 per second. Also increased the sampling frequency to 44.1kHz. These changes provide dramatic improvements in sound quality, which you can appreciate in e.g. Gyruss and Pooyan. The price to pay is slower execution. To make things worse, he had to (hopefully temporarily) remove some optimizations, so the above games will probably not run as well as before on slower systems.

- 0.20: Mirko Buffoni wrote a driver for Gyruss (Centuri 1983), one of his favorite games and one of the reasons why he started emulation. Big special thanks to Michael Cuddy (GYRUSS emulator), without help and information this game would probably never be done; and to Nicola Salmoria that fixed some of the sprites bugs that turned him mad and cleaned the code! Changed 8910intf to support 5 PSGs (Gyruss have them!). Issues: Some of the components of spaceship do wraparound the top of the screen for a while. Dunno if the original machine does.
