With the rerelease of the original Generation I games, some youngins might not be familiar with them, or veterans may simply be spoiled on newer features.
So hereâs some quick reminders for those who have never played/need a refresher on PokĂ©mon Red, Blue, and Yellow:
All PokĂ© Balls, of any type, have a chance to completely miss. Yes, even the Master Ballâalthough its catch rate is so absurdly high, itâs a one-in-a-million chance. Still, make sure you save before going and chucking it.
Steel, Dark, and Fairy types do not exist: the former two were not introduced until Gen II and the latter until Gen VI. (ex. Magnemite is a pure Electric, Jigglypuff is simply a Normal, etc)
Because Steel and Dark do not exist, Psychic types are overpowered as hell. While they are weak to Bug-type moves (although thereâs only 3 in Gen I), Ghost moves will only deal standard damage to them due to a programming bug. If youâre having trouble, get a Psychic-type.
The Mew exploit is alive and well in the 3DS rereleases. Make sure to do it as soon as you get to Cerulean City because you wonât get another opportunity. See Bulbapedia or Serebii to figure out how to do it.
Thereâs nothing under the truck in Vermilion Cityâs port, but it is there, and you can still go check it out for kicks.
Bind, Wrap, and other such âbindingâ moves work much differentlyâthey completely prevent the victim from taking their turn until the moveâs effect ends.Â
Multi-hit moves such as Fury Attack are all-or-nothing when landing a critical hitâeither all of the hits in the move will crit, or none of them will.
A PokĂ©mon that is frozen doesnât thaw over time. You must manually do so.Â
When a Pokémon wakes from sleeping, it will take the full turn.
Poisoning CAN and WILL KO the victim outside of battle if not removed. Keep Antidotes or Full Heals/Restores on hand.
You must manually switch PC boxes when you fill themâthe automatic switching was not introduced until Gen III. You wonât be able to capture any more creatures until you switch. The only reminder youâre going to get is when you attempt to throw a Ball when your box is full.
You have only 20 slots in the PC box before you must switch.
Thereâs no Special Defense statâitâs all done with just the Special stat. This can lead to Special sweepers that have absurdly high resilience to Special moves.
Certain type moves will use either Attack or Special stats in their effectiveness (ex. Grass uses Special, Fighting uses Attack, etc). The physical/special split wasnât introduced until Gen IV.
Leech Seed and Toxic use the same damage counter. Try inflicting both at once and laugh when your opponent rages.
Do not use Focus Energy or a Dire Hit! These are meant to raise the crit ratio of the active battler, however, they will actually lower it by 75% due to a bug.
The EV/IV system in Gen I is completely different.Â
Base crit ratio, as well as accuracy of OHKO moves such as Fissure are completely based on the userâs Speed. They will always fail if the user is slower than the target.
If Hyper Beam successfully KOs the target, the user will not need to recharge on the next turn. This also applies to destruction of a Substitute. In addition, Selfdestruct and Explosion will not KO the user if a Substitute is destroyed. This can be abused to great rage and hilarity.
On the subject of Substitute, the game wonât stop you from using Substitute even if the user is at 25% or less of their maximum HP. You can accidentally KO your own PokĂ©mon this way, so watch it.
If Rage connects, the user will become disobedient, and will continue trying to use Rage until it faints or is recalled. Pls calm down you are doing me a frighten.
The playerâs inventory is not sorted into pockets, and you only have 20 slots to use. However, your PC can store extra items, a feature that was removed in Gen IV due to being rendered obsolete.
Some other stuff thatâs missing or works differently
PokĂ©mon arenât gendered (barring Nidoran)
Pokémon cannot hold items
No breeding (caveat: a Day Care does exist south of Cerulean City and can be used to level up Pokémon for you, but you can only put one in at a time)
Cannot set an item to the select button
No day / night system or clockÂ
No shiny Pokémon or Pokérus
No way to re-challenge previously defeated trainersÂ
Stuff exclusive to the VC releases:
Wireless trading (havenât tried to see if thereâs online)
Some visual effects were toned down to be slightly easier on the eyes (most flashing effects, to consider those who may be sensitive to bright, flashing lights)
Jynxâs sprite in Yellow has been recolored to avoid racial concerns (which interestingly breaks the â8-bit ruleâ of color palettes)
In Yellow, you can play the Surfing Pikachu minigame as long as Pikachu is in your partyâit does not have to learn Surf as this is not possible in the VC versions
Thatâs all I could think of off the top of my head. Check Bulbapedia or Serebii for anything I missed.
