I recently released a free upgrade patch for the original RISC OS
version of the game 'Star Fighter 3000', which can be downloaded from
the usual place: http://starfighter.acornarcade.com/sfdownloads.htm

'Star Fighter 3000' is a futuristic combat-dedicated flight action
shooter rather than a realistic flight simulator, which places it in
broadly the same genre as games such as 'Apocalypse' and 'Terminal
Velocity'. It was first published in 1994.

The changes since the last version are as follows:

1) No longer attempts perspective division on coordinates that are
behind the camera. (Previously multiplied X and Z coordinates by
indeterminate values read from outside a lookup table.)

2) Corrected the speed of glissandos to match early versions of the
SFX_Handler module. (This effect was accidentally reimplemented at
half speed after the sound player was rewritten to support 16 bit
sound.)
