Memory MAP

[Chickenlump]

It might be helpful to compile every memory address known into one place. Here is the current listing compiled by Geiger.

That's the ones used in the coliseum

[Chickenlump]

7F01D3 - Guardia Forest tabs collected? (past and present) (bit 4 set for present,  bit 8 set for past if collected)
7F01D2 - Guardia Forest sealed chest opened? (past) (bit 80 set if opened)
7F01D1 - Guardia Forest Dead End sealed chest opened? (present) (bit 20 set if opened)
7F014A - Truce Inn sealed chest opened? (present) (bit 20 set if opened, If 7F004A has bit 40 set, you get powered up item)

Each chest and tab check a different address to see if it's collected.
If the guardia forest tab is collected, it sets bit 4 at 7F01D3, but when drawing it, it checks 7F00D3 to see if it's been collected, and hides it if it has...
Same with 7F01D1/7F00D1, etc...

If locations are different in your hacks, these types of addresses can be used for extra storyline counters and the likes. It would be good to go through all the events and make a master list of these.

If the guardia forest tab is collected, it sets bit 4 at 7F01D3, but when drawing it, it checks 7F00D3 to see if it's been collected, and hides it if it has...

This is the "Bug #4 Event Command 16 Wrong Address Displayed"  I mentioned in e-mail yesterday.  That's why I thought the bug should be in the Critical category.  The check address is supposed to be the same, 7F01D3.

Nice find with the HDMA colors.

7F01DF - Character lock status

7F01EC - Status of last battle fought 00 - You won/ran away, 01 - defeated

The sad part is, I read the email about an hour before posting.  
I have egg on my face. Boiling hot, scalding egg.

The HDMA colors aren't palettized like other snes colors, but still pretty easy to edit. I'll post again tommorow with the ROM addresses for these.

Could you show a small pic of the coding...I want to see what lil detail you used to do that stuff...Like bit math byte math Mem-to-mem etc...

What effect are you wanting to see exactly? These RAM addresses can be modified with event code in TF, but some of these addresses are always being updated and cleared and changed, so using events to write to some of these addresses (like the HDMA colors) won't do any good. Most of these are being edited and discovered with Geiger's Snes9X Debugger, which allows for all sorts of information finding, and hacking of SNES ROMS, while playing the game.

There are some nice finds here. I really wanna see how those HDMA colours are worked out if they're not palette based.

Scroll Mask in RAM for the current location

7E1D1A - Scroll Left
7E1D1B - Scroll Right
7E1D1C - Scroll Top
7E1D1D - Scroll Bottom


soooo.... one map, and as many rooms as you can fit in it, and through events (value to mem) you can set the scroll mask properties in the event to correctly block out everything else in the map, all proper like. WOOO

I used GetObjectCoordinates yesterday.  It's really easy to use so we'll definately be able to make use of the Scroll left/right/top bottom.  Way to go chickenlump.

--jp

[Chickenlump]

Make sure to change them before the screen loads (as soon as the event begins).  Changing it after will still change it, it just won't reflect visually unless you refresh the screen somehow (like going in and out of the menu).

[Agent 12]

if you put it in startup/load that would work right?

--jp

[Chickenlump]

I've tried it twice successfully, so it should work. Events load, and then the screen is drawn (I think). I'm going to see if I can find out more on this.

[Agent 12]

I'm wondering how to use the Epoch Memory correctly.  What I'm doing so far is using an assign command to 7f0290/292 and putting in the exact coordinates.  But it still isn't showing up.  So

Do I have to somehow say what map it is (I see that 7F029A)
Do I have to do some hex calculation (like location ->Overworld exits)
Something else?

Note:  TF 2.0 has 7f029A=Mem.DactylXCoord
