The gold hack works, but the mana one doesn't. I don't know about the rating one because I didn't try to complete a level after letting someone touch a gem.
However, an easy way to win a level is find the mana record (4b*1, changes location for each new level you start), change it to your maximum, and freeze it, then use meteor after meteor (remember holding shift). If you want to win the classical way and enjoy tower upgrades, instead, search for gold (4b*1, like said before) and change it to an high number. Don't freeze it, when I did it the money continued decreasing after each tower bought, like it should normally do, and I couldn't find the record anymore with cheat engine. Then, use the mana hack to cut out everything and build every tower you want. Like said before, the tower exp is a double, but it's useless because you'd have to change every single tower separately. The exp AoB hacks does not work with me.
Note: I'm currently using firefox. With chrome it could not even find some AoB in the game, I don't know why.
For the skill points hack, it is important to freeze, so you can buy every upgrade in short time (even if you change it to 56567547, it gives you only one point more). So, repeating the whole process, level up, search for 3 (4b), purchase an upgrade, search for 2, purchase another, search for 1, and only with the zero you should find the correct record. Change it to 1 and freeze it, then return to the upgrade screen, and you can click everything you want without having to come back to the main menu screen to re-enter to the skills one, or having to change the value in cheat engine after every upgrade purchased.
About the .sol files, the one you have posted so far does not work with me. I kept my savegame after replacing it, except for the fact that it changed my level to 2, so I had to start over because even after replacing with my backup it was still fucked up. Maybe it is because I have two files in the folder, and I actually have 2 folders (I don't know if one of them is for Cursed Treasure 2, but the names are both "Cursed Treasure.swf"). I tried deleting my files and applying again my backups (both folders) and it worked: losing a game you get the last three badges. My advice is the same as the others' one, get the easy badge on your own. With the meteor hack, it should be pushovers. I wasn't able to edit it with minerva, there are no explicit records, so I actually finished the game on my own using the hacks I described above. I am level 16, which is the minimum possible (the one you obtain playing each level only once, and getting brilliant the first time), so it won't be so suspicious in the high scores list. I attached the files you need to get the badges.
BTW, crazy request but... is it possible to do an AoB hack that lets you build every tower type where you want (temple on ice, for example)? Or even in the path?
