IT IS NOT TRUE

MAYBE IT IS TRUE and EVERYTHING ELSE is USERFAULT? Could be.

How do you mount? How do you install? Did you read the README?
Did you work through the guides?

I did "mount D D:\"
then I did "D:\install.exe"

I read the README more or less ^^

Seems there's a difference between reading and understanding. Well, if you only mount a d:\ drive, where do you want to install the game to? A little hint: have you ever seen a PC without a c:\ drive?

then, what must I write ?

60 seconds guide to getting your game to run in DOSBox

Thank you so much

Got it working? The guides are mostly a good startup and work for
the very most of the games.

it works, the game is installed but I can't play, it'a about 1 or 2 frames per second, it's ABSOLUTELY UNPLAYABLE

Use dosbox 0.70 and set core=dynamic as well as cycles=max in your dosbox.conf

it still unplayable ...

Then try playing with the core/cycle settings some more.
What pc/processor do you have?

I have a win 2000 (bought in 2001 or 2002)
I don't remember for the proc 😕

Then you probably have a p III or similar processor. It might be too slow to play gp2, as gp2 originally needed a pentium to run at reasonable speed.

Me, I have a Pentium Mobile 1,6 GHz (Centrino). The speed is ok and I can play gp2 in svga and with all graphical details.

For me, though, setting cycles=max is not the best solution for this game. Somehow the cycle guessing does not work 100% for this game. It's better if you set the cycles to 65000 or similar, core=dynamic and then AFTER STARTING THE GAME manually set the cycles up to ca. 85000 (for my machine).

it's worst than before ~~

you have to play without textures to get a good speed
Dont know why textures tax emulation speed that much (same with Fatal racing for instance)

ok I'll try

it's much better but the sound is awful 😵

anyway, thanks to all of you

the sound is perfect in GP2, so i guess you didnt run the setup or something
