Ecstatica 2 DOS/Win95 Debug Symbols #18
Description
Just to let you know both Ecstatica 2 (DOS, WIN95) watcom executables have debug symbols which can be tested with your tool.
I got some xcode related errors that may be related with my setup:
[1759756556] [WARNING ] Offset != entry["end"]: offset: 0x1cc38, entry["end"]: 0x1cc3c [1759756556] [WARNING ] Length != entry["end"] - entry["start"]: length: 0x0 (0), entry["end"] - entry["start"]: 0x4 (4) [1759756556] [WARNING ] Offset != entry["start"]: offset: 0x1cc38, entry["start"]: 0x1cc3c [1759756556] [ERROR ] Error: command failed with exit code 1: [1759756556] [ERROR ] /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/objdump: error: unknown argument '--architecture=i386'
but the convertion tool kept going and was able to produce multiple files, but I am unsure they are all complete.
I'm sending the game's dos version and the log and output_plain files in case it helps.
I've made a small script to dump the variables and function names into IDA
