Can't generate toml file for Spider-man Edge of Time
Ive been trying to see if SMEOT generates anything but Im getting inconsistent failures, as in there been one instant where it creaes a blank toml but all others have just done nothing. This is the log from my latest attempt, what am I missing?

there can be 2 problems, first, your paths are wrong written or XenonAnalyse are unable to read properly the base address from the game and it won't generate the toml, so i'm gonna give you my setup to make it to work properly.
1.-try using XenonAnalyse "C:\Users\Nevan\Desktop\Spider-Man Edge of Time\Default.xex" "C:\Users\Nevan\Desktop\Spider-Man Edge of Time" , do not use the square brackets., maybe you can have some problems for using spaces in the path so you will need to change the folder name to Spider-Man-Edge-of-Time
if the problem persists
2.-try editing the xex.cpp file from XenonUtils like this (only add the red dotted lines of code, watch out because there are 2 lines of code that already exist, these are the contents of the conditionals)
this is how it works for me (i already added the lines of code to my xex.cpp file
the content inside the toml
I couldnt get the first method to work so Ill try the ccp, but what did you use to edit it?
I was able to change the cpp and rebuild the project but it doesnt give a toml file.
you need to use idapro or ghidra to identify a pattern of the jump tables and modify the XenonAnalyse\main.cpp file so that it fits the logic of your game

1.- you need to find the way to get the toml file at least with an empty toml from xenonanalyse (i use visual studio and remember to use clang to debug the project)
2.- if the toml file says "# Generated by XenonAnalyse ---- ABSOLUTE JUMPTABLE ---- ---- COMPUTED JUMPTABLE ---- ---- OFFSETED JUMPTABLE ---- ", probably you will need to find the pattern of the jump tables as @derlineUn says

Can you please clarify where I look for the jump tables pattern.
at the bottom of the main.cpp file there are some patterns that you can use as a starting point to look for the pattern in your game. You need to use a disassembler to search for the instructions, a free option is ghidra, just search for ".xex plugin for ghidra" and install it, although it is good for beginners, ghidra is very difficult to use, I strongly recommend you use IDA Pro.
Im looking around there, what should I be considering?
if you are using Ghidra and the xex plugin you need to search for patterns that appear in the bottom of the main.cpp file in the folder of xenon analyse, and you will need to change the pattern in that file it looks like this
this is a quick example from battlefield 2 modern combat
As you can see battlefield has that pattern, you can find them quickly in Ghidra by searching for bctr and filtering the results for namespace you will see a text that say switchD label or switchD_some numbers
OK, Ive started going through those now, but how do you know which switch is which, or if it even corresponds to the switch, or if say addi and rlwinm switch places or they contain different terms like subi?
Hi. Ive been able to generate the absolute table now but not the others. Im also not sure how to integrate the other terms used into the main.cpp. I assessed and grouped the locations based on the instructions at those locations, but how do you suggest I proceed?
This is what Ive done:
lis, rlwinm, subi, lhzx, lis, addi, ori, add, mtspr, bctr 82375cc4 82296d9c 82293934

From what I have seen with games like Minecraft, Edge of Time, and TASM1, it seems like you will need to adjust the search pattern like @derlineUn mentioned. This is most common in games mader after 2010. ideally, you should for XenonRecomp, replace the main.cpp in XenonAnalyse with this one here:
And run the analysis tool. Then you will generate your jump tables 🙂
I was able to get all tables bare a few to work using derlineUns method but I had to give up I just dont have the technical ability to go further unfortunatley
