BGI hook:
|
||
Usually game folder contains BGI.*. After first run BGI.gdb appears.
|
||
|
||
BGI engine has font caching issue so the strategy is simple.
|
||
First find call to TextOutA or TextOutW then reverse to function entry point,
|
||
until full text is caught.
|
||
After 2 tries we will get to the right place. Use ESP value to split text since
|
||
it's likely to be different for different calls.

At some point the beginning four bytes to search for were removed, but the difference below were not corrected? Or maybe they were?

I don't have all these games so no way to confirm which (if any) are wrong.
|

But the first difference (the important one since it's the one detecting offset=arg3, all others give new) seems to be four bytes off when hooking https://vndb.org/v8158
|

...but maybe it's not? Maybe I discovered a new difference?
|

I think the safest option is to just add the new? difference as a case that detects offset=arg3 since either way one case will detect offset=arg3 correctly.

And all the other cases fall through to offset=arg2.
