Chrono Cross Modification / Re: Element Grid Growth Formula
« Last post by glennxserge on May 14, 2024, 07:59:38 pm »
Well, another year has gone by, and I finally had some time to sit down and plug away on this problem again.  Not solved yet, but I'm much closer now.

There's a bunch of weird MIPS stuff in the post battle routine that took a while to sort through, but I was able to unpack the element growth tables and verify that you can alter this table and unlock a slot anywhere in the element grid at any level, provided the character's stat block has the right mask to allow it. 

The growth tables are explicitly defined as 100 consecutive 8 byte strides.  Each 8 bytes represents one star level, with the character's growth stat at 0x03 determining which of the 8 bytes is used for their grid.  I've compiled the standard 8x8 element grid with the table values that correspond to unlocking that slot as a reference, which I'll list below.

Code: [Select]
    Element Grid
1  2  3  4  5  6  7  8
-----------------------
02 0C 16 20 2A 34 3E 48
03 0D 17 21 2B 35 3F 49
04 0E 18 22 2C 36 40 4A
05 0F 19 23 2D 37 41 4B
06 10 1A 24 2E 38 42 4C
07 11 1B 25 2F 39 43 4D
08 12 1C 26 30 3A 44 4E
09 13 1D 27 31 3B 45 4F
These values are actually pretty easily derived, despite the game's obtuseness in how it generates them.  Given a row and column, the slot values is:
column * 10 + row + 2  //Decimal values, indexes start at 0

The table that the game generates ends up at 0x80101448 through some sort of DMA transfer, but I'm unfamiliar with doing traces of DMA requests through emulation.  There's probably some way to find where it's coming from.  That'll be my next test.  In the meantime, here's the full, 100 star level entry, that represents the element growth for all characters:

Code: [Select]
☆LV Growth Pattern Index
----------------------------------
0 FF FF FF FF FF FF FF FF   <--- 8 FF's mean the level up routine skips entirely
1 07 07 07 FF 08 08 08 07   <--- a single FF means that one growth index skips

So for example, if you wanted Serge to unlock the most upper right slot in his grid at star level 1, after defeating the Komodo dragon boss, you'd change the first byte on line 2 from 0x07 to 0x48.  Like this:
Code: [Select]
1 48 07 07 FF 08 08 08 07
That's the short of it, but if anyone knows how the DMA stuff works, I'd love a pointer.  no$psx does spit out some debug TTY messages for when the DMA transfers happen and which interrupts get set, I just don't know how to interpret it yet.  Getting a little further here will help me figure out where the table comes from, and hopefully mean we can more easily modify it. 

Edit: Oh and I've compiled this info in a google doc that has a little better formatting.  It can be found here-> https://docs.google.com/spreadsheets/d/1uWDsskF8QeLrxV0DXz-7It5X9FZosdwmdJ9F1sUKYn0/edit?usp=drive_link

Chrono Cross Modification / Re: How to extract NPC overworld model & texture

Woah, great work GrobycFTW !  That must have taken a while to figure out. 
I always wanted Miguel to be a playable character.  I'll have to try it out, and it gives me a good reason to give the purple cat tools another shot (I always run into some problem when I've tried).

Hey, Booster!

I know it seems I’m takin’ HELLA long w/Trigger but I just have the Rainbow Shell left to do and it’s off to the Ocean Palace. I have to pick up sommore sealed chests too. I was thinkin’ abt it today and I know it seems like I’m playing a lot of games at the same time but this playthrough of Chrono has been really meaningful to me I dunno if it’s bec of all our talks in this thread too but: it’s helped me become a better me. It reminded me of a time where I was careless as a child is but everything seemed to always just work out for me. I just needed that carefree feeling or thinking back. I’ve started to do the push-ups everynight now and all the pain I had in my neck is now gone and upper shoulders, it was really all due to me just being I dunno maybe still depressed and being a lifer just laying about not taking care of myself. This might seem random but CT helped me do stretches on my bed that eventually got that knot out of the leftside of my neck, I rem one night I didn’t crack but I crunched and WRENCHED!!! my neck to the right and that spot finally disappeared so I’ll always remember CT and our talks about exercise, getting older, etc. I don’t want to talk to other guys abt it. You’re a really cool guy and you remind me to take care of myself now that I’m living all alone by myself. Namaste ::bows::

I’m tryna finish Atelier Escha & Logy, tbh I just wanna go back and platinum the first game Rorona cause I want a PS3 plat lol. I’m tryna get thru Steins;gate VNs are easy I just click X really fast through it half-reading just getting the gist. And on-for Switch I tried out Luigi’s Mansion 3- I wanted to get your thoughts on it cause my friends on Discord don’t really play Switch too much and you seem to be versed in’it. The vacuum is so much fun to play with just sucking everything on the screen. I’ve kinda put away LUNAR: SSH cause the music lulls me to sleep like a siren …

He secured the goods. My Dad and his friend got a PS5 Slim wDiscdrive in Manila today I can’t wait to try it out. I foresee myself getting super obsessed about video games from now on I just feel that excitement in my veins again. I’d love to know what titles you’re into, esp NON-JRPG since I’m so curious

Anyway Have a good one!

General Discussion / Re: Finally, vtubing as an OC "Schala"
« Last post by yatowek on May 10, 2024, 12:01:39 am »
So, a good portion of you might know I've vtubed as... myself, full Toriyama design and all.. However, because of C&D always being a possibility, and me wanting to do some fundraising, etc, and flex my creativity without restraint, I spent about 5-6 months making a "reboot" -- original character, original backstory I'm still trying to figure out, but with the same name with 'Zeal' dropped.

Her weapon is the Masamune -- a different one of course, which is conjured using her inner mana into solid steel (think Tenchi Muyo weaponry wordle unlimited) and it can also split into 2 blades for each hand.

I love the works in that version

Hello!

Link’s Awakening (remake) was great. I managed to find all 32 Pieces of Heart and all 50 secret seashells so I did everything, can put the game on the shelf and not have to look at it again. The ending wasn’t surprising to me at all,—only because the game and its characters (esp. the bosses when you defeat them!) gave so many hints as to what would happen if you wake the Wind Fish from its sleep I wasn’t shocked at all. I do think I managed to get the secret ending and it showed Marin in the sky and if you re-load your completed save the game forces you to make the island is un-touched and you wake up outside the last dungeon & everyone is fine contrary to what the cutscenes show. So, I dunno! 🤷🏼 ((Truth be told,—I did follow a 100% complete walkthrough on YouTube LOL only bec I have soo many games to get, and beat and get-through I just wanted one gimme I can finish in 15 hours have done everything and be proud of myself. Hehe.))

Yeah, after this experience I’m gonna look into trying to play some of the earlier Zelda games I missed out on. Def before Tears of the Kingdom & Breath of the Wild. I do look for those games to play in-between taking breaks from epic JRPG games.

I haven’t secured the PS5 Slim yet but it’s in the works. Been talking to my Dad’s friend (I just call my Uncle?) who stays in Manila, and seeing if he can secure me a brand-new one. I’m still taking my time w/ other games so I’m in no rush…

CT—I just finished another sidequest, I only have 2 more to go. The one about “someone close to you … you should help them fast” I have no idea whose it about I had thought Lucca/and her mom but I already did that one. Been appreciating the Trigger as an amazing JRPG I can see myself re-playing it years down the line and really immersing myself in the experience I wish I wasn’t playing so many games at once but it almost excited me in that way. I’m gonna push tthroguh to the end like you say but I almost don’t want it to end. Loved the scene with Frog at Cyrus’ grave and their friendship they only showed a few scenes of them two together but it seemed like 2 stoic friends and kinda was like big brother-ly. Pretty cool shit.

Nice on Harvestella! I’m just playing whatever comes to mind when I can. This week it’s been Atelier Escha & Logy and Puppeteer for PS3. I’m also interested in starting up Luigi’s Mansion 3 for Switch since I got it. I think I’m just excited to pick up the PS5 and pick up where I left off on the PS4 before it died (since it’s backwards-compatible). I was on such a good trip too: I left off on Dragon Quest Builders cause it reminded me of Survivor and you had to build a shelter and forage for food, and build a little community. I’m also looking forward to catching up with the times and playing games like Horizon and Yakuza Kiwami and just feeling like I’m in modern-gaming? I’ve been stuck on the PS3 for way too, long…

Aside from gaming: Been doing push-ups everyday. Been noticing I need to up my food just noticing whenever I eat just rice and vegetables (I get my workout in/notice progress) but I feel a little weak and my workout wasn’t like URRRGH!!!! I got some burgers a few days ago and 2 pizzas which’s lasted me these last 3 days… and the work outs have been AMAZIN’!!! I want to feel stronger instead of getting weaker. I’ve been bugging the workers on the farm to make me dumbbells too. But anyway yeah, just taking more time to exercise everyday and my fixation is just on staying consistent and everyday doing the push-ups. :)

Have a good one, Boo!!! :)

I'm back! Sorry for the long absence, real life has just taken it's toll.

Link’s Awakening is pretty cool. I know you’re talking about the really classic GameBoy version but I’m playing the remake on Switch. I was thinking you must really know your games if you’re talking about GameBoy Zelda cause I pretty much just started out on SNES with my RPGs.

Both, actually! I first played it on the original GameBoy, then bought the DX version for the GameBoy Color (which added a bonus dungeon). The remake is an outstanding remake, though. It has all the charm of the original, it's just that the graphics had a makeover. The gameplay and overall game plays entirely the same, which is awesome. I wish all remakes were this solid! Anyway, glad you're loving it!

One thing I really love about the Zelda series is that, up until Breath of the Wild and it's sequel, the Zelda series were generally games you could pick up and finish in ~20 hours. They are a great break to the grind of jRPGS.

Did the ending catch you off guard at all? I always found the ending pretty sad -- Koholint and all of those on the island were all just a figment of the Wind Fish's dream. It was sad to see them all snuffed out like that.

Speaking of remakes, I hear the Super Mario RPG remake is like that. :D

So met up for lunch and dinner w/ the parentals and they sat me down and told me they thought I haven't been spending money and having fun with my life here in the Philippines so instead of a PS4 Pro I'm thinking about going ahead and just picking up a PS5 Slim.

Nice! Did you get a PS5 slim? You'll need to pick up Final Fantasy VII Rebirth, if you did!

Yep not too much just same old same old.

Same. I've been swamped with life responsibilities. The weather's warmed up here, so I've put in my garden and we've gotten more animals, including some ducks. It all keeps me very busy, but I enjoy it. I haven't been gaming much, to be honest.

I did decide to rush straight to the ending of Harvestella. It also had some post-game content, so I grinded through that got done as quickly as I could while skipping over most of the optional stuff. It was a pretty solid jRPG and there was a lot I liked about it. The storyline was time-travel oriented, but I'll save spoilers in case you ever play it. In fact, there was one scene where I swear it was intentionally alluding to Lavos...

Since I've wrapped up both of those games, I haven't played any video games in a few weeks. I've not picked Yazuka 0 back up, although it's possible I will sooner or later. I enjoyed the ambience, but the story and gameplay was just so-so.
