    The events settings looks similar to the quick match from GT6.

    Yeah, it does. Another feature from the beta that is still in Gran Turismo today is the Time Attack events and the News section. You can tell that the online beta definitely set the stage for how Gran Turismo would go online in future titles.

    As per usual there are many more vehicles accessible on the Gran Turismo 4 First Preview demo than what you are able to select normally.

    With this being a later build of the game some of the car models are slightly different. The Honda S2000 for instance was originally present with the roof up.

    I'm going to see if there are any other circuits present on the demo. You have a choice of 3 normally.

    Good stuff! You should make a video of this :)

    The graphics seem to be better than the final imo.

    His YT channel has not been updated in quite sometime now. He may have forgotten about GTP, and the other GT betas that we still need to find out. I have more questions about the PS3 betas like GT:HD and GT5P.

    GT HD in original idea should have been split into 2 games : GT HD Classic ( basically GT4 on 1080p and 16 cars , and every car and track could be bought for some money ) , and GT HD Premium ( the GT HD we know, now only the Concept remains to us ).

    Funny thing is that GT HD in original had the premium impreza ( later disappeared) , and also there's 900° animation .
    This could be seen also in the official GT HD Concept and in first videos of GT5 Prologue.

    I still feel that GT:HD Concept still used some leftover data that no one has found yet. If we can find the binary files and just regular files for the cars. Like GT2, it should be in there waiting to be found, so far we only have seen two different Eigers, that then Eiger Nordwand that we got in GT5P.

    It could be related to GT4 in some way, but I think they were going the Free-To-Play route with buying tracks & cars.

    Here's the first version of Eiger, with the Impreza.
    The offscreen video shows the HUD Map of the track.


    Chase cam here :)

    Initial D Hybrid Stage.

    On another note I managed to fix the rather prominent graphical obstruction preventing me from using the emulator in hardware mode and decided to take a few more and a few better pictures of what appears to be a very early envisioning of El Capitan.

    I also managed to open nursnow and got a brief glimpse of what it looks like before the emulator crashed. I've attempted to access this one several times and 99 percent of the time it refuses to take me beyond the loading screen. However, I did manage to open it and whilst it crashed before I could identify the layout its clear that this one is very early being little more than a floating black stretch of road.

    Early El Capitan looks so cool :O But in a different track kind of way. I really like how it is in the final, but this seems like a pretty (though unfinished) place to drive on. Kinda reminds me of that one forest-y japan track in Enthusia.

    From what I can tell, in the last image, their could be something in the program that will not let you in the track, maybe you can try editing the global file in the game if possible. Sadly, I can't do this because my PC is weak as crap, but I would like to attempt something like this.

    One question, is it possible to find out exact horsepower figures specific Turbo or NA upgrades would give to each car?

    Excellent thread, keep up the great work!

    Don't they add a certain percentage instead of a constant horsepower figure? That's what I always thought, at least.

    Not really, some cars gain more from the same Turbo/NA upgrade, some less.

    It's a percentage. However some cars get slightly different percentage for specific parts, mainly turbos and n/a mods.

    Most things like ECU multiply the car's power by a percentage, like 103% in this example if i remember correctly. So technically you can calculate the amount of HP your car will make with some maths.

    So a car that's 300hp, when adding the ECU will make 300 x 1.03 = 309hp. Add in a turbo with a 200% power spike (the New Beetle stage 3 turbo iirc), and then you'll have either 309 x 2.00 = 618hp, or 300 x 2 = 600hp (the only thing I'm not certain of is if the power scales on base HP or HP with current mods installed.

    A way to know would be to install the turbo and see if adding the ECU adds the same amount of HP than instaling the ECU on stock power. I think the game scales on base HP.

    I conducted an experiment and Turbo and NA level upgrades seems to be the only parts where there is no fixed percentage increase.

    Buy Sirion CX and Honda Today. While Sirion CX gains gets 90% increase after buying Turbo Lvl.1, Today can't hit even 50%. I wish I could present actual figures, but my sheet I was working on got corrupted.

    That is why I want to know if somebody can get the Turbo/NA increases for each car using codes or special program without taking each car to a tuning shop.

    Use this. I included a program called GT3 garage editor that I found a while ago with some trouble that lets you modify save files (and that works on pc) to make hybrids and my GT3 PAL savedata (uncompressed) so that you can load it into the program and look at the values. You should be able to find what you need with it, such as percent upgrades to parts. :)
