Authentication code

The encoded part of HOF2lap-output. It is this code used by me for verifying your laptime.

Example extract of a DOS-screendump:

CC stands for Computer Cars. Also often referred to as the "AI" (Artificial Intelligence).

Chicane-cutting

On certain tracks, it is possible to take shortcuts. GP2 does use black-flags to prevent most shortcutting, but this is not very effective in some locations. Curva della Roggia at Monza and Busstop Chicane at Spa are two obvious examples. HOF2.5 doesn't allow shortcutting, and with the help of GP2LAP it was possible to ban it completely!

GP2LAP

The verification software that is used to log various factors that can influence the performance. HOF2.5 uses a special version that does some other things, too.... Like making shortcutting impossible, and warning you when some settings are wrong. Read the GP2LAP & HOF2LAP Howto's to find out more.

HOF2LAP

The first generation of verification software. HOF2LAP scans saved hotlap replays and games to detect the used BHP, car setup, laptime etc.  The latest version is now used to work in cooperation with GP2LAP. Read the GP2LAP & HOF2LAP Howto's to find out more.

Replay

The file that you get when you save a hotlap (or game) within Grand Prix II. Can be played back on another copy of GP2. It contains driver input, performance factors like BHP, driver and track name, framerate... But NOT things like carshapes, textures and the processor occupancy. Note that there's a difference between the information in a "normal" replay, and a replay saved while GP2LAP is active.

Slowmotion driving

Slowmotion driving is the result of the internals of the GP2 game engine. Instead of dropping frames when the CPU isn't capable of giving you the configured framerate and graphics details , the engine stretches gametime. This helps in getting better laptimes, and is of course against the spirit of hotlap leagues. Read more about this important subject.

Target Laptime

Laptime that can be considered as a fast laptime if you drive on this track according to the HOF2.5 rules, in the official trackslot and with default setup (the standard GP2 car setup). I used the standard setup to test the new tracks so no-one can accuse me from gaining an advantage.... Ain't I a nice guy?

Time-multiplier

Closely related to the track slot issue below. Each trackslot in GP2 seems to have its own "timefactor". If you use the same track in each of the 16 slots, and you drive identical laps around them, the times shown by GP2 will differ with a certain factor. On the other hand, the time in reality will be the same on each track! Only in some of the trackslots, the time displayed by GP2 will be identical to the time in reality (if you don't drive in slowmotion anywhere on the track).

Track slot
The trackslot is the position of the track in GP2. Interlagos is in slot 1, Aida is in slot 2... Adelaide is in slot 16. Each track is a file in the /GP2/circuits/ directory. So we have f1ct01.dat  upto  f1ct16.dat. (tracks are only copied to the harddrive if you do a full install of GP2). With the arrival of new tracks, it was discovered that the laptimes shown by GP2 change from slot to slot. If you put the same track in slot X and slot Y, and you drive identical laps, the driving will feel exactly the same but the times will differ significantly! If we want to compare laptimes driven by different people, it is important that we use the tracks in the same slot. "Putting a track in slot 1", is as easy as copying the trackname.dat file to the circuits directory and renaming it to f1ct01.dat. When you play the game, Interlagos (slot 1) will have been replaced by the new track.
