Gameplay / Re: Unused/useless variables safe to use in savemap? (PSX)
« on: 2014-10-23 16:33:40 »just because its not shown on the save map does not mean its unused. there are some spots that we know are unused but you have to check the documensts. becareful if you set some things the game may crash at some points or one very specific one. you can use the unused var under the test tab in black chocobo to compair slots to see what changes when testing to make it a bit easier to spot.Great, thank you! So looking at your notes, if I delete those two potions from the dead guards at the start (md1stin), I can use those values for my own purposes?
please see: http://blackchocobo.sourceforge.net/wiki/index.php?title=Savemap
for a more updated savemap. (i have not updated the qhimm one in abit)
and https://drive.google.com/file/d/0BxqH9L8_QubjV0EwTnJmbGlKdmc
for some of my notes that are not on the savemap . i have other notes that finish off all the used field vars for items (most of the notes focus on items not progression)
as for the offsets they are not as stright foward as you might think 1/2 are the same address one bank is used for 8bit access the other for 16bit access. (all the field used banks have this dualility) some blocks addressed by the field are not saved.
you can also view the fielditemlist from ff7tk for all offsets and bits
https://github.com/sithlord48/ff7tk/blob/master/data/FF7FieldItemList.h
you should also look at FF7Save struct
https://github.com/sithlord48/ff7tk/blob/master/data/FF7Save_Types.h
there might also be some more hints located in FF7Save.cpp as well since some of the "unused" data (z_#) is accessed outside the struct.
But how did you know Var[15][32] correlates to Z_38[44]:0? Whats the difference between Var and Z values, and how do you work it out? I looked at this specific slot in the Black Chocbo test data and saw: 0F 15 00001111 - that means the save already has the two potions and some more stuff in reactor (but not the poison materia you mentioned later).
So earlier you said "as for the offsets they are not as stright foward as you might think 1/2 are the same address one bank is used for 8bit access the other for 16bit access. (all the field used banks have this dualility) some blocks addressed by the field are not saved." so what does that mean exactly for the above? How does that affect me if I just want to delete those two potions and use that value elsewhere?
Thanks for the Black Chocobo link, that's a great program. I looked in the test data and understand how it works with the memory slots, but I'm not sure how to use those unknown vars in Makou Reactor yet as I don't know which variables it points to (or is it something we all have to work out)?
Sorry for the questions, I'm very new here and just trying to understand
