Level Select Selection Issue

I have re-arranged my Level Select so all zones are now on the left. The selection for that works. Here's a picture:





I wanted to add an entry for HPZ, and I did so in PlaneEd. Selection was broken, so I went to make a copy of EHZ's level select highlight array, and modified it to the HPZ values. Now, HPZ Act 1 selects sound test, and does what sound test does. Act 2 is not selectable at all! I know there must be some offset table telling the game where to find what zone, but my bigger problem is the highlight. I looked through all of the Level Select code for some kind of maximum selection value, but changing the values that look like they could be this value simply breaks the level select completely. Can anyone point out to me where this index would be, like in what method or what it's ASM command is. Thanks so much, since I really want this fixed.

 

The reason why it's not as simple as you want it, is because it's been written in an optmized way, in order to save not only space, but also time, enabling the processor to perform these operations, the quickest way possible, so I'm pretty sure that the Sonic 2 level select menu is very hard coded in that respect, and you'd need to know a fair bit about the VDP to get it the way you want. Unfortunately, that requires you to learn how to operate the VDP and manipulate it's mapping plane spaces.


Until then, 'fraid I can't help you.

 

Would it be easier just to add some kind of second Level Select, or go to HPZ when holding A and selecting EHZ? Just an idea.

 

It would be easier of course, but it would also be pretty dumb

 

If you know the values, or have altered values and the selection has changed to say, from EHZ to sountest, then your proberly on the right track just edit them until its positioned right. Also I think you have to change how many entries there are, like say it was 13, then change it to 14 if you want to add another ect. The one that esrail done for sonic 1 which is a replicar of the sonic 2 levelselect for sonic 1 is a bit easie to understand but again its for sonic 1. I wish I could go on ssrg at home, and check my s2 disam but I'm afraid my laptop thinks website is down lol, so thats all I have for my knowledge plus I'm currently at work.

 

I did get the positioning and stuff right, it is just the amount of values. It's just a matter of finding that value. I've looked at that code for at least an hour and tried changing almost everything, but no luck.

 

I am pretty sure there is a table that needs to be expanded as I have done this before and didnt seem to have any problems... the thing to remeber is if you add something to a table you must expand the table to allow the new entry if you get what I mean?


edit: Have a look at this label in the S2 asm file.... Misc_9454:

 

I have added an item for HPZ there ($800 and $801) and added a selection index thing there also. Now the selection table looks like this:




byte_96EE:


; First Column


dc.b 3, 6, 3, $24, 3, 6, 4, $24 ; EHZ 1+2


dc.b 5, 6, 5, $24, 5, 6, 6, $24 ; CPZ 1+2


dc.b 7, 6, 7, $24, 7, 6, 8, $24 ; ARZ 1+2


dc.b 9, 6, 9, $24, 9, 6, $A, $24 ; CNZ 1+2


dc.b $B, 6, $B, $24, $B, 6, $C, $24 ; HTZ 1+2


dc.b $D, 6, $D, $24, $D, 6, $E, $24 ; MCZ 1+2


dc.b $F, 6, $F, $24, $F, 6, $10, $24 ; OOZ 1+2


; Second Column


dc.b $11, 6, $11, $24, $11, 6, $12, $24 ; MTZ 1 + 2


dc.b $11, 6, $13, $24 ; MTZ 3


dc.b $14, 6, $14, $24 ; SCZ


dc.b $15, 6, $15, $24 ; WFZ


dc.b $16, 6, $16, $24 ; DEZ


dc.b $17, 6, $17, $24 ; Special Stage


dc.b 3, $2C, 3, $48, 3, $2C, 4, $48 ; HPZ 1+2


dc.b $12, $2C, $12, $48 ; Sound Test



Doing this still doesn't let me select HPZ correctly.


Lips2k8: There must be some other value somewhere, since expanding the table didn't help. If it helps if I upload my complete level select code, tell me and I'll do so.
