Rockman 8 FC route

General note: thunder claw does not work like it does in real 8, in 8FC the best way to use it is to just mash it against an enemy. Tornado hold is also useful for getting up ladders very fast, but before you leave the top of the screen, quick weapon switch to remove t hold from the screen, because if it blows you off the screen you need to wait for t hold to end so you can fall back on screen to grab the ladder and trigger the screen transition upwards. Quick weapon switching works like it does in MM10 rather than MM8, if you weapon switch, if you have any shots on screen quick weapon switching will immediately make them disappear.

Frost
Tengu - this fight sucks a lot
Clown - you can save a single cycle on the final block/climb section using tornado hold
Grenade - you need 30 bolts after this stage, ice wave the snake pit after the midboss if you still need bolts - e tank is worth it. Use thunder claw against the midboss.
Shop - Buy high speed charge
Sword - Grab the big bolt next to midboss hole, suicide if you miss it. Use high speed charge on the sword fight.
Search - get the bolt hidden behind the foreground on the third screen (in the alcove you need to slide into), and the bolt behind the thorn bushes in the next screen, you can t hold to get the e tank quickly if you want it (refights suck a lot)
Astro - This stage is terrible
Aqua - get the bolt after t holding the spike ball at the bottom in the area after the midboss, need 100 bolts by the end of the stage. Use thunder claw against the midboss.
Shop - I'm really iffy on this because I haven't tested it, but in my current route buy energy saver, you don't get ammo refills between wily stages, bosses use up a crap ton of ammo, and then you need to do refights and wily, so I think energy saver is worth it. The other two alternatives worth looking into (lol) are buying high speed charges (one time use item) for some of the refights, or to cut out all the bolt pickups in the last 4 robos and to go into the Tengu refight first and intentional game over for a full ammo refill. I haven't timed it but I feel like just buying energy saver is the best option because the bolts really aren't that far out of the way in the second set of 4 robos.
Wily 1
Wily 2 - don't get partners still, just astro crush the boss and he dies
Wily 3 - This stage is terrible, for green devil you want to flame sword him 2 or 3 times (I forget) and then you switch to thunder claw. I looked for a bit but I honestly couldn't find a better way to kill green devil, he's really bad.
Wily 4 - the moved frost and astro to the top left and right, the rest of the capsules are in the same spots basically. On machine just use water ballon, for capsule flame sword deals the most damage and you can get 2 hits in per cycle if you're good, if he gives you a high spawn or you're low on health you can get an easy 2 hits in with homing sniper. This stage is really rough if you're not familiar with the boss fights, so the e tanks from Grenade and Search if you picked them up are very nice.
