Weird, I'm sure I have the latest iso because I downloaded it last night. I redownloaded it from https://www.mediafire.com/file/qw71cbrclfukbh2/Winning_Eleven_7_International.7z/file to make sure I got the right one, hashed both files and got the same hashes. I played on PCSX2 tooI just tested the game and have no crashes. Started a new ML campaign first in the Northern League. Game loaded fine, cutscene showed fine, fixtures loaded, match loaded and played to the final whistle, negotiations loaded fine and the next match too. Tried the same with the Southern League and all fine there too.
Please ensure you downloaded the ISO again as I had updated it a few weeks ago to fix any crashes in Cup, League and Master League mode. Also this needs to be played on an emulator not real hardware as I have changed the LOD levels which may crash the game on actual PS2 hardware. If I get time I will release a version that is compatible with official PS2 hardware.
