Hello, everyone. Since the new VBA player seems to be working now, how about this game as a possible run?

Depends on the difficulty. On Crazy it's really hard to keep stuff interesting, and I believe the fastest method would involve buying no items so you're stuck using Dragon Feet/Mach Punch with your ally/allies being stronger than you

Would you even be able to get any good allies (= the Shitenou) without spending time to boost your reputation? Edit: Of course you couyld use one of the Omake modes to get techniques. Or mess with other settings to make the gameplay interesting (change gravity to allow for air combos etc).
someone is out there who will like you. take off your mask so they can find you faster. I support the new Nekketsu Kouha Kunio-kun.

I don't know the japanese names but if you mean the Generic Dudes, they'd take far too long to get. I think the only partner who's really worth it would be Ivan, unless you play fair (slow) enough to get Thor.

The Shitenou (Kinoshita, Mochitzuki, Taira, and Kobayashi) are the four main bosses of the game.. they all attend Reihou Academy. You can get any of them to join but at the end of the game Yamada kills all of them for betraying him so you have to fight that battle alone. If you can wait that long without a full team you could get Gouda and Godai once you're at Reihou.. ..but again, all of these people need reputation, which you don't really have time to amass.

...that, and the fact that you take a reputation hit when you hit a boss during their intro spiel, pretty much cancels that out. It would be better to play as either Alex or Ryan (Kunio/Rikki) alone, and get Gary (Sugata) at the beginning, or Rick (Maeda) at the park. Both characters have higher starting stats, so they can be used as support/a shield as necessary. Actually...I don't think you need reputation to get Ivan (Gouda), so if a little backtracking is ok, you have a third, powerful member for your group. If you've got him and enough reputation (hmm) you can recruit Tex (Godai), although I wouldn't recommend it--with three non-Zombie allies, Slick calls in help that really slows the game down. Actually, you get reputation every time you get knocked down (sympathy?), so if you let your partners handle the enemies and just run into a wall repeatedly, perhaps you can gain enough points.

I don't think Ivan(Japanese Name Here) needs reputation, all it takes is a run-about which wouldn't take too long compared to how awesome strong he is.

After the NES playaround with two players, which had me rolling on the floor holding my guts in from laughter, I found this cool remake of the game on the Game boy Advance. It's actually a lot better than the NES version in terms of gameplay and graphics. What do you guys think? Would a GBA run of this game work?

Gathering from only these 2 threads (1 and 2), there isn't any way to get up-to-date information on the GBA game, River City Ransom EX. Gotta start somewhere, I guess... This will be my thread, containing information, RAM addresses and values, and other stuffs about the game that can be useful to get a speedrun going. I appreciate if anyone else is interested in doing the run, or share their findings about the game. ----------------- This is my current submission (00:08:39) This is the current submission discussion I don't think it's gaining traction, so I think maybe one has to tackle the high grounds first in order to at least get some publication going... To start, this is my current findings with RAM values. Beware that different ROMs will have different RAM addresses. Please correct me if I got anything wrong, or if you know what other info I missed: Latest findings

Store items and their leveling stats (Part 1):
Numbers - How many points it will add to your stats total, accumulatively.
Green Text - Emphasis on potential leveling shortcuts.
Red Text - Special Techniques (Moves)
I probably will continue to update this when I find more information. The goal is for me to understand what the game is doing with all these numbers, and see if it's possible to do a Crazy (Hardest difficulty) speedrun. There are other factors at play, such as:
  • Figure out how to control the randomness of the enemy gang type when entering a new area.
  • Figure out what optimal stats is preferred to give the most damage.
  • Figure out if I need to increase my willpower, which affects how quick you recover after taking a blow that knocks you into the air. Would it make it more interesting?
  • Figure out how to quickly nab the best technique to unlock. So far, I have one in mind that I use prominently when playing regularly.
  • Find out if playing Solo or having an ally is more interesting.
  • Find out if playing a non-protagonist character as Solo or have allies join up over the course of the run is more interesting.
That is all.

Updated OP thanks to feedback saying different ROM variations will have different IWRAM variations.

Small hiatus aside (due to me being unrealistically put off with the way I thought Bizhawk is capable of doing), Bizhawk's Freeze Address and Poke Address does not permanently modify the game's IWRAM. This actually sucks because I would truly not be able to manipulate RNG the way I wanted to do. Ideally, if the modified RAM values are permanent, as in, ignoring whatever the game calculated and only using frozen address values through poking it, then the game would truly reach capabilities of making a great TAS. I can confirm address 2AB4 is indeed the current "calculated" lump sum of your player character's money. However, at the start of the game, it's only when you start entering a new area, does the game then starts keeping track of your current money count. This also means, in the first area, no matter what money you picked up on, it doesn't update the value until subsequent area changes later on. Address 2424 hold the previous calculated lump sum of your player character's money and doesn't update the value at all.

In my opinion, I think these 3 techniques are all you ever need in a TAS run, be it aiming for the best times, or dealing with secret events. Swap Dragon Kick with Mach Punch if you're playing as Ryan.

Found a useless strategy in RNG manipulation to get 3rd prize Lotto Tix ($1000.00) There is a random number counter that starts from 0x270 and decrements until it reaches 0x0. When it does reach 0x0, it loops back to 0x270. Another counter was found where the random value, which I found out, is tied to another value. This value is coined as the "determinant" (by me), where, each time it decreases the counter, it increments itself. It's a 4-byte counter, guaranteeing the Lotto Tix lottery results are unique every 0x270 times. The trick is to manipulate the CPU enemies to make any actions, to start decreasing the random value, and reach a specific random number counter and determinant as fast as possible, in order to reach a particular combination of the random number counter and the determinant, to get the calculating Lotto Tix prize. The upside to using this strategy allows you to always get your Lotto Tix prize of whatever monetary value you want, but the downside of using this strategy is it takes a bit of frames to do. Here in the GIF, I'm just lucky that, after exiting the Merlin's Secrets shop, I can get the 3rd Prize within 500 frames from the frame I exited the shop.
