Basic Questions and Answers Thread

OK, so I finnaly got the options menu ported, and I set up a screen mode options. Looking at savestates, I can see that the flag is actually set. The flag increases by 1, but I have to multiply it by 4 to get the screen mode index. So I use this code to do that:



move.b ($FFFFC90E).w, d0
add.b d0, d0


add.b d0, d0


move.w d0, ($FFFFF600).w ; Go to selected mode



THe deal here is that I always end up on the Sega Screen. The RAM adress contains a Word, but I read from $C90E to only read the second byte. I have no idea why this doesn't work. This code should work, right? This just kinda confuses me. Thanks for any help!

 

You are moving a word to $F600. Change it to move.b

 

sonic2 questions!!


Level order, i know how to do it...but is there a way of making ËHZ"not the first zone?


Adding zones i found a guide for s1, not s2.... any tips?

 

TitleScreen_Loop:



moveq #0,d0
move.w d0,(Two_player_mode_copy).w


move.w d0,(Two_player_mode).w


move.w d0,(Current_ZoneAndAct).w



to...



moveq #0,d0
move.w d0,(Two_player_mode_copy).w


move.w d0,(Two_player_mode).w


move.w #$XXYY,(Current_ZoneAndAct).w



XX = zone ID


YY = act ID

 

I changed it to move.b (how could I overlook that?) and made some small changes to the code, with one being a way of seeing if it works. Here's my code now:



move.b ($FFFFC90E).w, d0 ; Load selected mode into d0
add.b d0, d0 ; Multiply once


add.b d0, d0 ; Multiply again


move.b d0, ($FFFFC90F).w ; Debugging Code


move.b d0, ($FFFFF600).w ; Go to selected mode



So I load the contents of d0 back into a RAM Adress for debugging, it turns out it is always 00 for dumb reasons. Anyone know why this happens? I'm just completely discombobulated about why this code doesn't want to work.

 

People, I have a problem: How would i load PLCs for an extra char? It worked for Mapping and animation i think...

 

I'm trying to fix this problem:


I've put Flicky in place of the rabbit in Scrap Brain zone and kept the chicken in the level, but when I've loaded the level, only the chickens were in the level, and at different speeds. How do I fix it?

 

I can't use FSUTIL, but I want to make my levels from scratch. I want to make the tiles and palettes in SonED2. Do any of you have any empty .bin files I can use?

 

I also forgot this code:

Code:

Obj28_VarIndex:	dc.b 0,	5, 4, 2, 6, 3, 4, 5, 3,	0, 5, 1



Obj28_Variables:dc.w $FE00, $FC00

		dc.l Map_obj28

		dc.w $FE00, $FD00&#59; horizontal speed, vertical speed

		dc.l Map_obj28a	&#59; mappings address

		dc.w $FE80, $FD00

		dc.l Map_obj28

		dc.w $FEC0, $FE80

		dc.l Map_obj28a

		dc.w $FE40, $FD00

		dc.l Map_obj28b

		dc.w $FD00, $FC00

		dc.l Map_obj28a

		dc.w $FD80, $FC80

		dc.l Map_obj28b



Obj28_EndSpeed:	dc.w $FBC0, $FC00, $FBC0, $FC00, $FBC0,	$FC00, $FD00, $FC00

Obj28_EndMap:	dc.l Map_obj28a, Map_obj28a, Map_obj28a, Map_obj28, Map_obj28

		dc.l Map_obj28,	Map_obj28, Map_obj28a, Map_obj28b, Map_obj28a

		dc.l Map_obj28b



Obj28_EndVram:	dc.w $5A5, $5A5, $5A5, $553, $553, $573, $573, $585, $593

		dc.w $565, $5B3

Pretty much every hex editor includes an "Insert" function. Simply insert like 10000 bytes with 00 and save it as whatever.bin.

 

From what i see, XVI32 doesn't.

 

So, quick recap. Get a hex editor, type in the appropriate number of bytes, add 00, and save as cz.bin. Sounds straight forward, I'll try it.


EDIT: I've just noticed something! The Nemesis art format comes in a compressed and uncompressed state. So, after I make the file, do I have to copy and compress the copy? If so, how?

 

look at where the char. plc is loaded (under SonicLoadDynplc or similar) and add an extra char. check. you should also binclude the file....

 

well If you are talking about making your own custom art for your hack that's in nemesis format, then yes you would have to compress it.


as for actually compressing it, one way I would suggest doing it is by using SonmapEd and save whatever nemesis art file you are editing and Compress it like that. At least thats how I did it anyway.

 

Oh no, I'm working on Sonic 1. it'd be Incbin


Doesn't matter, as I've adapted to shittles the echidna's glitchy look. Thanks anyway.

 

That was for sonic 1 but ok. glad i could kind of help...

 

So, Moon and I tried to add another level as a kind of Hub. We removed it because it didn't work, but now we suspect what causes it, and I can't get it back in correctly. This is what happens:


">" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344">


The PLC and Main Block Load Cues are set up correctly also. Anyone know why this happens?

 

I also have a small question. I want to make a save feature in my hack. But i need to know how to do it, I mean, if I have ideas of how to program it i will try this. This question is for people with more advanced knowledge than me.

 

Learn ASM. Well, do you have any knowledge how the SRAM functions or how to write/read to it? Modify your header to let the Emu/console know there's actually SRAM. It's pretty complicated. You only write data to odd adresses, a word is the size of a longword, and a longword the size of 2 longwords. This is the kind of thing I really don't want to explain and provide code here, but PM me or get on my IRC channel and I'd be more than happy to help you.

 

I know ASM, but i don't know SRAM stuff. I'll PM you.
