IncludeFolders=textures), this will add all files (including those in subfolders) to the game's root folder. Useful for organizing PVRsSTG02.ini in the mod folder, it will read that instead of pattern.ini when patching STG02. 1
630C2=FF07
630C2 is the actual address in the file (memory address 8C0730C2 minus 1ST_READ key 8C010000), FF 07 are the bytes to be written at that address in the order they would appear in the file, so the value 0x03FF would be written as FF 03, and 0x07FF would be FF 07. Since the FF part doesn't change, this can be optimized to:
630C3=07
The other lines are pointer replacements. Basically you look for bytes 00 80 B6 0C and replace them with 00 37 C8 0C and so on. In the patcher, there's the "pattern patch" thing which looks through the file and patches all specified pointers. However, unlike byte patches (like the first line), pattern patches replace actual pointers, not byte sequences. So to convert what Speeps wrote to a pattern patch, you need to flip those values like this:
patch1,0CB68000,0CC83700
patch2,8C78EA40,8CC91A70
patch3,8C78EA44,8CC91A74
patch4,8C78EA48,8CC91A78
patch5,8C78EA4C,8CC91A7C
Save that in 1ST_READ.ini and place it in the mod folder. Then in mod.ini you need to include the file to be checked for pattern patching in the PatternFiles field. The whole file (without the texture stuff) would look like this:
Name=Windy Valley
Author=Speeps
Version=1.0
Description=
Autodemo=True
PatternFiles=1ST_READ.BIN
[1ST_READ.BIN]
;Expand object list for Act 1
630C3=07
Since the patcher is being developed alongside the mods made for it, I'm experimenting with different ways to make changes to files. This is how it's set up at this point.
