Chrono Trigger DS was probably TOSE's most perfect port to date. I really can't find ANYTHING to complain about it, there are no slowdowns, no loading times, all features from each version prior is included, and even the original music is identical. Maybe a few sound effects sound slightly different, but I really can't see much difference. They didn't even wash out the graphics or distort anything. I'm assuming they couldn't do much to hurt the game since it was on a system that was many many times more powerful than the original system.
Honestly speaking, I probably WOULD have been quite happy with a GBA port at the time. I wanted the game to be ported to GBA back when the system was big. But now, I'm glad they chose DS.
Here's the basic rundown of the other SE games ported by tose to GBA though-
Final Fantasy 1&2 DoS- This was originally two separate Wonderswan color games. Then later, a PS1 game. And then even later, a GBA game. The wonderswan benefited from being a full remake, instead of a port of the NES games. The GBA one in particular, I can't find anything wrong with. The music and graphics were slightly downgraded from the PS1 game, but that's minor and understandable.
Final Fantasy IV Advance- This was also a port of the Wonderswan game made by Sting, which in itself, was once again NOT a port of the SNES game, but more of a remake. Unfortunately, both WSC and GBA versions had some annoying bugs in the battle system. And the GBA version at least had some rather annoying lag in battles and the mode7 world map parts. Graphics were sort of upgraded from the SNES game. The sound was too electronic.
Final Fantasy V Advance- I hear complaints about this one, but I actually think it's a pretty good port by TOSE's standards on GBA. I had little slowdown, I didn't see much washing out of the palette, and I didn't mind the music quality. Of course, then I played that sound hack a while back restoring the music quality, and realized my ears are off.
Still, not too bad.
Final Fantasy VI Advance- My favorite game in the entire series. Sadly, It actually had some annoyances, most of which will be fixed in this hack. The palettes were too bright, the music was off, and there was some noticeable slowdowns in battle and mode7 parts when things get hectic.
Honestly, a lot of early GBA ports could benefit from palette restoration and sound restoration. I can think of one of the first GBA games, which was Disney's Magical Quest, port of a SNES game.
Just take a look at the SNES game-
