A program to generate optimal Star Power paths for Clone Hero.
Download the latest version from the Releases page. If you're on Windows, you will need to have installed the latest Visual Studio Redistributable.
If you are unfamiliar with the intricacies of reading paths, read this guide.
CHOpt has two versions, a command-line version and a graphical version. The graphical version has the same options as the command-line version and is self-explanatory enough. As for the command-line version, an example usage to path Trogdor on Hard and save the output to trogdor_path.png is
> CHOpt.exe -f trogdor.chart -d hard -o trogdor_path.pngOnly the -f parameter is required, the difficulty defaults to Expert and the path is by default saved to path.png. The full list of arguments can be found by passing -h or --help to CHOpt, or by consulting the table below.

| --sqz, --squeeze | Set squeeze % |
| --ew, --early-whammy | Set early whammy % |
| --lazy, --lazy-whammy | Set number of ms of whammy lost per sustain |
| --delay, --whammy-delay | Amount of ms after each activation before whammy can be obtained |
| --lag, --video-lag | Video calibration, in ms |
| -s, --speed | Set speed the song is played at |
| -l, --lefty-flip | Draw with lefty flip |
| --no-double-kick | Disable 2x kick (drums only) |
| --no-kick | Disable non-2x kicks (drums only) |

If you would like to conveniently run CHOpt on a setlist and you happen to be on Windows, I made a PowerShell script that I've put here. Change the four variables then run the script. The simplest way to do that is probably to open the folder the script is in, double click the top bar and type in cmd then enter to open a command prompt in that folder, then run the command
> powershell -ExecutionPolicy Bypass -File setlist.ps1- Boost for Boost.Test
- CImg to produce images
- libpng to save pngs
- Qt 6 for the GUI and various utility code for both versions
- SightRead for parsing charts and midis
- zlib is a dependency of libpng
CImg is vendored in the repo. Boost, libpng, Qt, and zlib will need to be provided by anyone compiling CHOpt for themselves. Boost is only required for tests. libpng and zlib need to be set up so that FindPNG can find them, and the same is true for Boost and Qt (see this and this page for details). SightRead is included a git submodule.
- FireFox2000000's Moonscraper .chart and .mid parsers were very helpful for getting an initial idea of Clone Hero's parsing behaviour.
- Dinoguy1000 and shadoweh helped me make sure CHOpt runs on other peoples' machines.
- Various users for feedback and testing, including 3-UP, ArchWK, Bromik, CyclopsDragon, DNelson, GHNerd, Haggis, Jdsmitty1, Joel, Jrh, Kyleruth, LightlessWalk, Littlejth, Lucretio, NicoBrenChan, RandomDays, RileyTheFox, Taka, Venxm, and Zantor.
If you have any bug reports I would prefer they be reported on the GitHub page, but feel free to send them to me on Discord at GMS#5303.
