5 overworlds, one for each appliance
1 signpost script for returning to rotom-n

each appliance OW has this script: http://pastebin.com/YUUiAg2M
just alter the @start so that 0x4001 is assigned to the following values and the string buffered for the respective appliances:
0x0 = microwave oven [person ID flag: 0x2c8; person number 11]
0x1 = rotary fan [person ID flag: 0x2c4; person number 10]
0x2 = refrigerator [person ID flag: 0x2c5; person number 9]
0x3 = washing machine [person ID flag: 0x2c6; person number 8]
0x4 = lawn mower [person ID flag: 0x2c7; person number 12]

the reversion sign has this script: http://pastebin.com/s3TCpKAD

special 0x154 should be a pointer+1 to this routine: http://pastebin.com/zEX1vRC7
special 0x6 should be what JPAN's hacked engine special 0x6 does
special 0x17 should be what JPAN's hacked engine special 0x17 does
callasm 0x98722ED should be replaced with a call to the location+1 of this routine: http://pastebin.com/FwZf5R3L
callasm 0x98722A1 -- " -- : http://pastebin.com/KvBX7skm
callasm 0x9872101 -- " -- : http://pastebin.com/XKdtWkxx

the scripts and routines assume that:
move 0x13b = overheat
move 0x193 = air slash
move 0x3b = blizzard
move 0x38 = hydro pump
move 0x1B5 = leaf storm
pkmn 0x214 = rotom-n
pkmn 0x30E = rotom-fire
pkmn 0x30F = rotom-water
pkmn 0x310 = rotom-ice
pkmn 0x311 = rotom-flying
pkmn 0x312 = rotom-grass

it's a mess but it works, lol
