Alright, I have been asked to share the routines I made for form(e) changing in Platinum Red & Blue multiple times, and I finally found the time to do so. This thread will be updated as I clean up old routines and create new ones. Enjoy.

Rotom & Deoxys
Spoiler:
This routine simply changes the index number of a Pokémon in your party.
.thumb

getpokeoffset:
	push {r4, lr}
	ldr r0, var8004
	ldrh r2, [r0]
	mov r0, #100
	mul r2, r0
	ldr r0, poke_slot_1
	add r4, r2, r0
getandsetnewindexnumber:
	ldr r2, var8005
	mov r1, #0xB
	mov r0, r4
	ldr r3, pokemon_setattr
	bl jump
recalc20bytes:
	mov r0, r4
	ldr r3, pokemon_calc_effective_stats
	bl jump
	pop {r4, pc}
jump:
	mov pc, r3
	
.align 2
	var8004:			.word 0x020270B8 + 0x8004 * 2
	poke_slot_1:			.word 0x02024284
	var8005:			.word 0x020270B8 + 0x8005 * 2
	pokemon_setattr:		.word 0x0804037C
	pokemon_calc_effective_stats:	.word 0x0803e47c

/*insert anywhere. set var 0x8004 to the desired pokemon's slot and 0x8005 to the new index number, then callasm this routine+1.*/


Burmy
Spoiler:
These routines will transform any Burmy that enters the battlefield according to the terrain.

The first routine, burmytransformjump:
.thumb

main:
	ldr r3, burmytransform
	mov pc, r3

burmytransform:	.word 0x________	@address of burmytransform.asm here

continue:
	str r0, [sp]

/*insert at 08030D40*/
That routine loads a second routine, burmytransform:
.thumb

getdex:
	mov r1, #0xB
	ldr r3, pokemon_getattr
	bl jump
	mov r6, r0
	ldr r3, species_to_pokedex_index
	bl jump
compareburmy:
	ldr r1, burmy_dex
	cmp r0, r1
	bne ender
getform:
	ldr r0, idx_for_battle_screen_elements_by_env
	ldrb r0, [r0]
	lsl r0, #0x1
	ldr r2, area_to_burmy_cloak_table
	add r2, r0
	ldrh r0, [r2]
	cmp r0, #0x0
	beq ender
burmeeeeeeeeeeeeeeeeeeh:
	mov r0, r4
	mov r1, #0xB
	ldr r3, pokemon_setattr
	bl jump
ender:
	mov r0, r6
	ldr r3, return
jump:
	mov pc, r3
	
.align
	pokemon_getattr:			.word 0x0803FBE8
	species_to_pokedex_index:		.word 0x08043298
	idx_for_battle_screen_elements_by_env:	.word 0x02022B50
	area_to_burmy_cloak_table:		.word 0x________	@pointer to burmytable here
	pokemon_setattr:			.word 0x0804037C
	return:					.word 0x08030D48
	burmy_dex:				.word ____		@dex number of burmy here

/*insert anywhere. place a pointer to this routine in burmytransformjump.*/
Now, this routine uses a so-called burmytable. It has ten halfword entries, being either zero or the index number of the following forms:
plant plant sandy 0000 0000 0000 sandy sandy trash plant
Insert it anywhere, and place a pointer to it in the routine above.


A note on spelling
Spoiler:
Please use the word forme for legendaries and form for other Pokémon. Thank you.

I really can't wait for the rest, but I do have a question. Will you be doing the moves related to Rotom?
Nope, the moves can be handled from the script. Ask Bela if you want an example


(by the way guys, an ugly version of this first routine has been available for quite some time :/)

It changes the index number of the Pokémon in party slot X (var 0x8004) to Y (var 0x8005). Instructions on how to implement it are in the last line of the routine, as always.

Everything is just FR so far, until somebody ports it.

I'm sorry, didn't see this one at first. Typo: I meant 0x2 , which means if greater than. Special 0x9F will return a party slot from 0 to 5, and 7 if no pokemon is selected.
Also, for the full script you need to check if the selected pokemon is in fact a Rotom or Deoxys too, of course.

EDIT: whoops, seems like I missed the fact that in Platinum you never actually have to select a Rotom or a Deoxys... :/
Derp here, so I guess this would require one of FBI's routines instead.

On another note, what exactly were you referring to with Arceus and Giratina?
The routine that changes the index number based on hold item (and location).
