How to create a new version of The Soul Shrine

I wanted to create a version of The Soul Shrine in GBA Version of FF6 but in different way I know its not easy.And also how can appeared a set of monster consecutive one by one like did in FF6 advance and what place should I have put in World of Ruin.Is there a way to create a new version of The Soul Shrine?

P.S:
BTW this image shown is what I'm say.

Well, in your super atma(as guest) hack you enter into hidon cave and then warp to Gogo room... you should do a similar thing i guess...

The map you have to edit is obviously Cyan's dream.

In order to call many consecutive monsters, you have to check when all the monsters of the current formation are dead(battlescript) and then call a specific formation using F2 command(i use it a lot )

I'll leave the rest of explaination to the others.

FF6 T-edition implements this without sacrificing anything else, that I know of. You could study that, but it's Japanese and heavily modified. It also implements the full Dragon's Den, though not with quite all the minibosses (as he had used most of his extra 128 enemy slots elsewhere).

Uhm, i have the feeling that he doesn't need of jap version of the game...

You can have consecutive battles like the GBA version, the only difference is that each battle ends individually while in the GBA version has each battle wave on the same battle (without a battle ending with exp, gil and lvl up). This is map and event editing mostly, it's fairly easy to implement.

Actually it's really easy to implement a wave of a lot of monsters... see the previous post i wrote... with a proper check and F2 command you can even create a wave of 1000 formations... even an endless cycle, if you want

Yeah I removed my edit. I haven't touched a monster script in like 2 years, so my knowledge is all gone :/

You're either going to need to code a command to check the background being used or you're going to need expand formations (for formation check).

Why checking the background?

In Soul Shrine the background is always the same

Checking the background enables you to have monsters check for that specific one, and trigger formation changes based on that one. It'd be the only way to not have to use special formations.
