For newbies who is first time playing and those who wants play again (if some of you didn't remember how to edit a save just MUA & XML2 does) on Spider-Man 3 PC. According to some modder from via YouTube, if you want to play as the playable character inside Spidey 3's PC packs folder, here's the list you need to do:
1. Play as original Spidey first on new game start (Carlyle Part 1 and City Tutorial)
2. Exit game after auto save
3. Go to documents/activision/spider-man 3 to find main_save_data file
4. Open with HexEditor
5. Search ch_spiderman and replaced with following the list below (Large Alphabetic will work on the characters' working on the game):
A. CH_BLACKSUIT (original as ch_blacksuit)
B. CH_PETER (original as ch_peter while in DB)
C. CH_SPIDERMAN (original as ch_spiderman)
D. CH_PLAYERGOBLIN
6. Save it and WAZAAAM!!, ready to go & 100% success
Oh, there's a warning:
* If you switch with other Playable Path of Spider-Man (ex. Spider-Man > Black Suit), then switch again back to default unmodded Playable Path, as well as some mission that suddenly turned into one of 2 default playable Spider-Men. Following the bug list (3 Spider-Men only, mostly completed):
