*Xardion (U) : 0x7e0d02 : 30 : 5 : sephiroth2k

* Due to the weird way Xardion deals with sprites (storing them relative to position in level), the screen may
jump briefly when crossing certain vertical thresholds. If anyone has a serious problem with this I'll fix it, but I really don't think it's worth it.
** This mem follow address will jump up when text is present so you can read it and down when there is no text so you can play

.:HOW YOU CAN FIND ADDRESSES:.
You Need:
ZSNES, from www.zsnes.com
VisualBoy Advance, from zophar.net
PocketSNES, from snes.pocketheaven.com
A SNES ROM, from an undisclosed location

Extract all your files into a single directory, it will make things simpler.

+Finding addresses for SNES ROMS+
Step 1) Open ZSNES, and start your rom.

Step 2) Hold down ~ key to fast forward until you're at a place where
you can control the sprite you want PocketSNES to follow.

Step 3) Now go to the 'CHEAT' menu and select 'SEARCH'

Step 4) Select '2 BYTES', 'DEC...', and 'COMPARATIVE SEARCH'

Step 5) Click 'START'. Now return to your game, but DON'T MOVE.

Step 6) Go to 'CHEAT'->'SEARCH' and select 'NEW VALUE = OLD VALUE'
and click 'SEARCH' again.

Step 7) Return to your game and jump, changing your sprite's vertical
position.

Step With your sprite at a higher position than it was at when
you started, go to 'CHEAT'->'SEARCH' and select 'NEW VALUE != OLD VALUE'
and click 'SEARCH'.

Step 9) Return to your game and bring the sprite vertically down from
its previous location.

Step 10) Go to 'CHEAT'->'SEARCH' and select 'NEW VALUE != OLD VALUE'
and click 'SEARCH'.

Steps 11-X) You probably see the pattern by now. Repeat until you
have as few addresses left as possible.

Step X-Y) Now go to 'CHEAT'->'VIEW'. If you're lucky, you won't have
too many addresses left. Now highlight likely addresses and select
'ADD'. Modify the value of the address and see what happens.

Step Y+1) If you were lucky and modified the right address, your sprite
should be stuck at some height corresponding the value you entered.
Write down this address. If you weren't lucky, you're not at step Y
yet.

Step Y+2) Fire up PocketSNES.exe and add your ROM with the address
you found in the memory following box*, scale% set to 30 or so. Create
PocketSNES gba rom. *use format 0x<Address>

Step Y+3) Open said gba rom in Visualboy Advance, and see if it works.

Step FINAL) If working, post address at http://www.pocketheaven.com/boards/viewtopic.php?t=97
If not, try again.

Very nice...it works rather well


I don't mean to beg or anything, but do you think a Castlevania 4 follow address could be found?



Edit- Lol, the Gradius 3 follow makes the screen follow the tip of the whip in CV4

Interesting when the whip can be swung around and the screen goes funky

hehe. thats a cool effect. Looks like something that the GBA shouldn't be fast enough to do.

[sephiroth2k]

I'm in school (Java) right now, but when I get home I'll work on it. Might have to wait to submit (I think my ISP cut off my service - they seem to want payment or something), but I'll get it.

Oh and is there anyone who wants me to make a guide for finding memory addresses? It's very similar to finding them in NES games.

PS - Loopy, great work man - I watched PocketNES progress and am enjoying this PocketSNES as well.

If there's a systematic way to go through it sure, I thought it was just trial and error. I'm not so good with programming (only know basic stuff wih C, basic, ASM, HTML, and java) but I can try to do all of the other misc work that needs to be done.

Heh.. glad you like that one.. here's a few more:

Game : M.Address : Scale% : Offset

Super Castlevania IV (U) : 0x7e054e : 30 : 10

Skyblazer (U)(12134) : 0x7ef101 : 40 : ? NOTE: I know it's not playable yet

Demon's Crest (U) : 0x7e1034 : 30 : 10

Tweak the offset and scale% to taste.
Any other requests? I don't play many of the currently playable games.

All right.. basic tutorial time.

You need : ZSNES, rom you want to test, pocketsnes, visualboy advance

Step 1) Open up your rom in ZSNES
Step 2) Get to somewhere where no sprites (or as few as possible) are moving, and you can make your desired sprite move
Step 3) Go to the cheat menu in zsnes, do a comparative search.
Step 4) Return to game for a little while, then go to cheat -> new value = old value
Step 5) Return to game, move sprite. Go to cheat -> new value != old value
Step 6) Keep narrowing down values.
Step 7) Now you can go to cheat -> view. Now write down all the addresses with values that seem plausible (ie, less than 50000 )
Step Fire up pocketsnes, and drag the rom you want to test into it as many times as you have values for.
Step IX) For every rom, set scale% to about 30
Step 10) Going from top down following your address list, set each sepearate copy of your rom to have the corresponding value in your list
Step 11) Test in visualboy advance (With frameskip->9 and throttle->none and speed up -> on). Write down whichever value(s) work.
Step 12) Tweak scale% and offset till you get it the way you like.
Step 13) Post it here

Now that's a bad tutorial! Good luck.
Oh yeah, and *MAKE SURE* you change the scale% for testing, if you don't you won't see any following, even if you have the correct address!
Also, try to narrow down your possible addresses as much as possible, it would be a pain to test too many values.

Thanks for the guide. I hope a tutorial on finding speed hacks might be that simple.

What games do people need sprite following values for? I could try to find them for you too.

Great work sephiroth2k! I remember you from the pocketnes scene too
If you want to I can make this topic a sticky, but please put all the important stuff (found values, and the toturial) in the first post so it's easier to read.
