Delta-V is one of Bethesda's back catalogue games released for MS-DOS in 1994, which sets the player as a net-runner - basically a corporate hacker for the Black Sun Corporation, throughout a campaign that involves infiltrating corporations to steal data, sabotage or completely destroy them, while trying to defend Black Sun from enemy corporations doing the same.
Curiously the game presents this as a trench-runner, with you sitting in the cockpit of your virtual trace, dodging turrets, enemy fighters and obstacles that were placed by rival corporations to damage and destroy incoming traces frying the brain of the hacker who was piloting it.
I owned a boxed copy of this game that came on the most floppy disks I had seen for a game at the time (i think it was six), which gave me time to read the copious amount of lore that was in the manual while it installed. When it finally booted up the ominous soundtrack set the tone well for the dystopia the game presents. Launching into the first mission, i loved racing down the data trenches, dodging and weaving, towards whatever objective was next. Unfortunately i never got very far until years later and I was older when I reached the final mission (but never beat it).
Tracking down a copy to play fairly recently in DOSBox, I discovered some curious obstacles:
1. The CD version installs with it's save data location pointing to the CD (doesn't work because CD's are read only).
2. Due to the way DOSBox reports the time and date, meant that the copy protection would always fail, even with the right answer.
Thankfully a bit of config tweaking and a visit to the VOGON forums resolved both problems. The users there had discovered the timing error between DOSBox and Delta-V, so patched an exe to disable the time-reporting portion of the copy protection (making it work correctly).
Therefore I was finally free to run the dystopian data-trenches again and one day i'll beat that final mission to see the ending. One day...
