Hi,
is there any way to change the resolution screen to 4:3 instead 16:9? The game at the time was made for 4:3 monitors screens, so in 16:9 the game image it's shrinked....

That would be an issue with your graphics card scaling options. Basically, it's told to stretch images to fill the screen. What card do you have? There should be an option in its control center to change this. Also, the sticky at the top can offer some alternatives.

It's a ATI Mobility Radeon HD 5145, the screen problem it's only on this game, others seems fine, it should have a patch or something that we could change the resolution somehow, in game options i change the resolution nothing happens...

Assuming you're on a laptop. Open Catalyst Control Centre, find My Built-In Displays>Properties on the left, tick "Maintain Aspect Ratio".
Additionally, click on Preferences (top-right) > Hotkeys, Tick "Enable Hotkeys feature" and set a combination for "Toggle internal panel scaling modes". Then, when something looks stretched, hit the combination and see if it helps.

It's really not a matter of the game needing patching, sorry. If that doesn't work, again, check the sticky, it might work better.

Spinorial is correct. The game does output to a 4:3 resolution (the game only has settings for 4:3 so it must output a 4:3 screen resolution), it is your hardware that is stretching it to fill a 16:9 screen.

I've not used ATI graphics cards so I don't know the Catalyst software to be able to tell you where to look, though Spinorial's comment seems clear enough. Nvidia's software has a similar setting for their cards, and I always ensure that it is turned on as I prefer to play 4:3 resolutions in 4:3, not stretched to fill the screen.

I just want to add, thank you all of you, I just now decided to give this version of the game another chance, and the 16:9 Hutt-like stretched screen bugged me a ton.

For all the Nvidia people out there, in Nvidia Control Panel, under "Adjust desktop size and position", there is a scaling tab. I selected "Aspect ratio" but originally it did nothing, I had to go to "perform scaling on:" and select "GPU" from the dropdown, and went ahead and checked "Override the scaling mode set by games and programs" for good measure. "Override" did nothing while the dropdown was still on "Display". Selecting "GPU" is the key for me.

I can deal with the primitive graphics and resolution (I played this game to death and back on an N64 as a teen, I can deal with old graphics), but that aspect ratio was killing me. Black bars are better than Hutt-stretch.
