Do everything as usual up to dratini LG
after dratini, fly to viridian
ORB grimer, ponyta, meowth, dratini
Old man catches ditto
Burn heal dragonaite on ebuzz menu still gives red bar
Continue as normal until crazywarp
after kabuto LG, fly to celadon,
withdraw orbs, change boxes
do game corner + evolve + snorlax
warp to vroad from guardhouse (top tile of bottom left exit)
normal v road then pallet
fly to lavender after pallet
LG for koffing, orb stuff, deposit, change boxes 
Fight shellder trainer (hyper beam, ball)
get lapras, warp to seafoam
do seafoam and eggs and jynx

saves 2 resets (koffing and kabuto), and a fly (after snorlax)
but only 2 seafoam pokes go to party
but shellder does

If you have koffing:
Don't reset after machamp, fly to vermilion and orb instead
Do shellder, lapras, then seafoam
After seafoam, fly to pallet
After pallet, fly to vermillion
Eggs, jynx done
Same number of flies, but there may be a way to save 1 since we don't fly to lavender

Could also do Shellder+V road+pallet in box 5
And Celadon+Seafoam in box 6
Nicer warps+ box space but more scrolling for the seafaom warp
