Unfortunately yes. When you can choose whether to fight Magus or not, that decides whether he can join you or not.
After defeating the Blackbird [...] if Frog [or the Party] refuse [to fight Magus], Magus will join the party.
The main differences are:
All the PS1 version movies are included
New control scheme for DS
Several new dungeons and sidequests
Monster battle arena
1 new ending
Monsters & Bosses
You don't get the Masamune as a weapon until after a cutscene. When you get Frog back into your party, head to the North East of the forest you got him from. There should be a mountain (not the one you got the broken Masamune from). Go to the base of that and enter it. There, you will get the cutscene. Afterwards, Frog automatically equips it. It's ...
A simple way to hear any character's theme (assuming that they have joined your group yet) is to not have them in the party, talk to them at The End of Time and tell them you want to change your party, except when you're at the point where their sidequests are available. Regardless of whether you actually change your party or not, that character's theme will ...
Try going to the Black Omen.
There are three time periods where you can go to there. 1,000 A.D., 600 A.D., and 12,000 B.C. It's important to start with 1000 A.D. and make your way back, because if you beat the Black Omen in 12,000 B.C., it won't be there in 600 A.D. and 1,000 A.D. since you already beaten it (you've altered the future by changing the past!)...
I don't think the requirements of this have changed on any of the platforms.
Did you specifically initiate the event with Frog in your party at the time?
If you have Frog in your party when you head to the North Cape, there will be conversation about the curse. Consequently, Frog will fight the battle on his own. If you win in this scenario, then it should ...
Frog's Theme shows up the first time you meet Frog, near the beginning of the game. Following the first link you posted, if you use game save #1, slot #2, you should be right at the point where you meet Frog. My memory is a bit hazy, so it may be slightly before or after that-- once you've loaded the state, check to make sure Frog isn't already with you; ...
"Tech Points" are similar to experience, but they help to unlock more of the techs (and/or spells) each character has access to. Unlike in other games, you don't learn techs based on your level.
In the "Tech" menu, you'll see a list of the techs each character can learn, and you can see how many more TP it will take to learn the next one on the list. ...
You must first go back to where Marle vanished (that'd be the Queen's room — from the throne right and upstairs) and only then back to where the gate opened in the first place. Lucca has the device to reopen it.
I don't know about Android, but in the SNES/DS versions, you have to press the action/talk button when you get close enough to the rat to catch it. Once you do that, it'll give you the password to move through the next room.
This ending it's called in the wikia as Revenge for Cyrus
If you face Magus in Noth Cape with Frog on face to face battle, sparing him or killing him will result in this ending after defeating lavos.
Furthermore, killing or sparing him changes a little the final sequence but in both cases Frog becomes Glenn (human) again.
This is the answer I found on one of the Chrono Trigger wiki :
His main reasons for starting his war against Guardia were left out in the English version; however, in the Japanese version, he stated his intentions of gaining the power to immensely increase his chances of defeating Lavos. Seeing his strong magic and strange appearance, most people took him ...
Is this ever explained in a non-handwave manner?
The only explanation I can provide, is by using a real world example - Latin. Like "Caveman-ese" Latin is a dead language, but that doesn't mean it isn't still studied. Additionally, stories from ancient times might also hang around, but only as myth and legend. It's possible that this is what ...
Chrono Trigger for iOS does not 'sync' to iCloud in the way you are hoping.
I've played on my phone and seen that the save game does not sync my iPad.
To check for other games/apps (if you own them) look under Settings > iCloud > Storage & Backup > Manage Storage.
The apps listed under 'Documents & Data' sync between devices.
The apps listed ...
Here are the steps according to this Wikia, I haven't done these endings in ages but all of this sounds correct.
Ending 1e: Revenge for Cyrus
Method: When Frog and Magus face each other on the North Cape, either
fight and kill him or spare Magus' life
In the canon ending, Frog spares Magus' life, as killing him will not
return Cyrus. Magus ...
