Wait, a graphic style like Lufia 2 where you fight with a creature instead of directly?

Okay, one more guess: Robotrek

Maybe Chrono Trigger?

There are multiple characters fighting at the same time, but one of them is a frog, so maybe you just confused something?
Anyway, you should try this forum as well.

You said it wasn't 3D, but I figured that meant full 3d; While those two games (much like FF7) have images for backgrounds.

maybe Bahamut Lagoon


EDIT: Missed that it was already suggested

Rings of power!

I doubt that's it, but it's 3d isometric with some dragons in it.

Can you remember anything about it? The UI or anything? Can you draw a scene?

My two suggestions had 3D models in it and it's a no-go, so i will assume no for you too.

Septerra Core?

It's all 2d but has a 3d look from the usetric view. But I still doubt it.

I looked at your suggestions but it's too recent to be the game I look for. It was in the end of 90's and before 2005 or 2006 I would say, it's very "gameboyish"
no sorry :/
Thank you for your answer but it's not Rings of Power, the view is not Isometric but in 2D like old pokemon games. I don't remember exactly the UI but I would say it's like every Jrpg games with attack name, you select it in the menu and your monster does it.

Last thing BUT /!\ I DON'T KNOW if my memory created it or if it was like that, but I think you are in the "snow" at the beggining of the game, I didn't played very much so I think it's at the beggining

This was bugging me, so I kept digging and found something I'd never heard of that might fit the bill:

DemiKids

I feel so embarassed to say "no" everytime, I think the game is more "medieval" oriented and not "modern" like your game :) but the style is nearly the same, if I remember the game I'm looking for is not very colorful

Eh, you really shouldn't. Nigh-impossible internet investigations are always a fun little distraction, and especially so during the holidays where the general cheer goes so overboard that it starts to sound sarcastic.

Unless it's something painfully obvious like Final Fantasy 6, the console emulation possibilities are pretty much dried up at this point. I suppose it's possible that it was some old freeware or RPG Maker 95/2000 game, but finding detailed information about those is proving pretty much impossible. Some random possibilities:

Warrior Dragon
Pokemon: Evan's Adventure
The Midnight Avenger
Dark Skies

... But without detailed gameplay footage, those recommendations are based mostly on something vaguely dragon-looking or the possibility of Pokemon-style combat and a walkthrough's mention of early coldness possibly indicating snow. Needless to say, pretty thin stuff.

Thank you again for all your answers, but it's none one of them. I think the nearest game is Final Fantasy VI but it's not with robots etc, as I said, I don't remember very well this game I only have flash image (don't know if this sentence exist in english) so that's why I'm stuck to find it (for years) maybe one time !

To resume :
It's a turn base rpg with dragons, very similar to Final Fantasy, it's not Dragon Quest, it's in full 2D, when you move your character you see it from above. The fighting screen look like Pokémon with your creature at the bottom left and the opponent on the top right. The begginning of the game MAY BE in the snow but I don't know if i'm creating some information or not since this time.

anyone ? :/
