i did extract the fix rar u linked in ur previous comment
now the game crashes to desktop when i choose Thermal General on challenge Mod , and when i load a Nuke General Challenge
It works on my PC. No crash, no intro bug.
Is there a way to skip or remove him from challenge mode?
Yes, you can. Extract Campaign.ini (you need FinalBig to open .big files) and edit map rotations.
where is the Campaign.ini file ?
Search for Data\INI\Campaign.ini in !Contra009Beta.big.
Data\INI\ folder is empty
there is nothing inside the DATA> INI folder
