This seems pretty cool, just based on what you wrote. I'll check it out and come back later with comments.

And if you're looking for a tutorial on adding Pokemon in the disassembly, I made one right here.

Actually, adding Pokemon can make existing .sav's stop working. The size of memory in the save file reserved for Pokedex seen/owned flags is based on the value in NUM_POKEMON, which you will be increasing.

I just updated the original post to include screenshots.  I'm going to swap the pallets for Mareep and Ampharos in the next version.  (If you want to know how Flaaffy looks you'll have to play the game.)

I would like to add nine more "families" of Johto pokemon all as in-game trades.  I'm open to suggestions, but Marill, Phanpy, and Togepi are most likely going to be involved since they were considered "Pokegods" before the original US release of gold and silver.  If I add Cyndaquil, Totodile, and Chikorita (which is not decided on yet) there will only be a few slots left unless I add in-game trades... of course that would be an easy option.

I can add moves but they're not perfect matches to later games unless the script already exists in gen 1.  So Cotton Spore acts like string shot (only lowers enemy speed by one instead of two), and mud slap is a purely offensive move.

If you're wondering the rationale for letting Geodude learn mud slap at an early level, it is to fit with the Charmander/Squirtle/Bulbasaur pattern, but there weren't any low powered ground moves to choose from.  If you pick Gastly as starter, your rival gets Geodude because ground moves are super effective against poison pokemon.  If you pick Machop, your rival gets Gastly.  Gastly learns confusion pretty early on, so we still have the same non-transitive deal as the original.

It also mimics the difficulty settings of the original. i.e.; If you picked Bulbasaur you would have a pretty easy time towards the beginning of the game and a strong advantage against the first two gym leaders, Charmander is the opposite (and if it hasn't evolved into Charizard or learned Flamethrower yet, it can barely hold its own against Erika!).  Gastly is the "easy" mode because not much can touch it through Viridian Forest, and its psychic move will help you get through the pokemon tower and beat the first Gym leader.  Machop is the Charmander (or hard mode) of Lavender version because fighting types generally just sucked in the first gen.  There is no way to win your first battle against your rival if you pick Machop and it doesn't get much easier since you're expected to face like 10 channelers in pokemon tower and the grass/poison types in Celadon gym are all resistant to fighting moves.

Hope that gives some insight on some of the design choices I made.

I just found out about and fixed a bug which allowed you catch Mew in the Pokemon Tower.  Sorry to anyone who thought this was intentional, but that is too early in the game to catch a legendary pokemon and would make the entire game too boring.

Along with the bug fix came a glitch.  Where it used to just say "Wild MEW appeared" and treat it like a normal wild encounter, it now behaves almost exactly like the original Marowak battle from Red (as intended).  Only difference is the ghost sprite is glitched and I can't figure out why.  Here is what it looks like.

P.s. you can still obtain Mew as in the previous version after beating the Elite Four.  In fact you can catch her over and over because she respawns every time you beat the Elite Four.  (I haven't decided if this is a bug or feature.)

Thanks for the feedback, LateNightHacker, and I do realize the first battle is basically guaranteed to go a certain way based on who you pick.  If you pick Gastly you will win without taking any damage, Geodude you will take little damage, Machop you will definitely lose.  This kind of forecasts the easy/medium/hard thing I talked about earlier, and Charmander/Squirtle/Bulbasaur aren't really "balanced" either for the duration of the game (although for the first battle they admittedly are).

Machop learns Seismic Toss at level 9, so you can win your second battle against Rival if you're smart and maybe a little lucky.

My personal preference is to start with Geodude, then get Abra right away.  I've played through the whole games more times than is fun for anyone and usually Golem/Alakazam/Lapras is my final lineup.

Speaking of Lapras, does anyone know where the game pulls the value from that is deducted when you buy Lapras (Magikarp in RBY) at the Mt. Moon Pokecenter?  As late as it is now in the game, 500 bucks feels like a freebie and I can't find anything in the script that I can change to make it more expensive.

wisejustin, I can't tell you how cool I think it is that you are asking me for help.  I have actually only been hacking for about two months myself, so total n00b.

Unfortunately I won't be able to help you with your hack of gold, since I haven't even wet my feet in 2nd gen yet.  But I wish you luck and just keep at it, if you're like me you'll get more excited every time you figure out a new trick.

You could make mud slap use the bubble secondary effect, so it lowers speed instead of accuracy. It may not be perfect but it makes sense.

Can u give me a .jar

Just updated link to v1.5 beta, with Crystal's exhaustive help I now have Cotton Spore, Mud Slap, and Rollout working as intended.  This stuff is over my head so any future move updates will be at Crystal's schedule.  (I will still update to add new pokemon if I have time, and I'm still looking for advice on unglitching the pokemon tower Marowak (now Mew) ghost sprite.)

Enjoy!

Just uploaded b2.0 patch!

Barring anything crazy, this should be the last release that messes with your save state.  I have eliminated debug mode, so your PC will only have one potion when you start a new game.  This game is playable from start to finish, you can obtain all 151 Kanto pokemon, and 24 Johto pokemon are included as easter eggs.

Did you know there are 10 in-game trades programmed into red but only 9 accessible without hacking.  I kept the locations of those 9 the same, but I'll give you one spoiler.  The 10th trade is in Viridian Forest.  All trades will give you Johto pokemon.

Crystal has been working really hard to implement some of the new moves for the 2nd gen pokemon, but there are still a few left.  If you try and use something and it seems wrong or says "nothing happened," don't report that as a bug.

I fixed the ghost/silph scope glitch so now the actual sprite appears, and as intended, you can't catch Mew in pokemon tower.  Total of 175 pokemon in the Lavender Pokedex, I will not be adding any more so like I said before, no new releases after this should ruin your save state (take that with a grain of salt).

ShantyTown, wPokedexOwned and wPokedexSeen don't have to be moved around anymore. In pokered, their sizes are dynamic.
