Thanks Dominic but just now I played game from ROFS##.DAT instead of extracting them and the game didn't crash so now I have save from STAGE 2 which is enough to start working on supporting that stage, but still I'll probably will need saves from other stages soon, Now I can get saves from other stages (3, 4, 5, 6, 7) by my own since the game working that way but if you have some free time spend to get those saves go ahead that would help me I would spend spend saved time on tool rather playing game. I need saves for standard PC PAL version English
Edit1: Just have add support for STAGE 2 English version for now have test it with several rooms and it seems that it work. I guess now I'll work on STAGE 3 support. By the way it seems that I'll have to add support only for STAGES 1~5 cause it seems that the regular game use only those stages, and STAGES 6~7 used for mercenary mode I guess!?
Have applied sepia effect on BG and Mask.
Edit2: Have add support for STAGE 3 too, need more tests to be completely sure if it's will with all rooms in that stage though.
