A tiny, playful single-player roulette cheat for How to Fish.
Pick black, red, or green — RO steers the local roulette ball toward your color.
RO is a personal reverse-engineering project exploring Unity assembly inspection, runtime hooks, physics control, and safe patch generation. It installs a small local module into a compatible game build, letting you choose the roulette's outcome before each spin.
Built for personal, offline experimentation — not to harm the game, its developers, or other players.
- Free, Black, Red, and Green modes
- Detects compatible builds by structure, not a fixed version hash — works with renamed executables too
- Patch generated locally per build, with SHA-256 backups and one-click restore
- Refuses to patch anything it can't safely verify
- Download the latest ZIP from Releases and extract it.
- Close How to Fish, then run
How to Fish - Roulette Operator.exe. - Point it at the game's executable if it isn't found automatically.
- Confirm RO detects a compatible structure, then click INSTALL / REPAIR.
- Open the game, pick a color, spin.
Use FREE to disable assistance. Use RESTORE ORIGINAL (game closed) to revert to the original assembly.
RO locates *_Data/Managed/Assembly-CSharp.dll and checks the roulette types, methods, and fields it needs. Works across known and renamed builds while that structure holds.
No tool can guarantee support for future updates — if required members change, RO refuses to patch and leaves the game untouched.
Requires Windows x64, .NET 8 SDK, and your own local copy of the game (assemblies aren't redistributed here):
.\scripts\setup-references.ps1 -GameExecutable "C:\Path\To\How to Fish.exe"
dotnet build .\HowToFish.RouletteTrainer.sln -c ReleaseRO backs up the active assembly (SHA-256) before patching, and verifies the new patch before replacing anything. Always close the game first.
v1.0 is unsigned, so Windows may show an unknown-publisher warning. Only download from this repo and verify the ZIP against SHA256SUMS.txt.
