I was attempting to set up HMM on my Steam Deck for use with Sonic Frontiers. For reference, here is the guide I used:
https://linuxgamingcentral.com/posts/updated-sonic-frontiers-steam-deck-modding-guide/
By the end of it, Tinker opens up fine but HHM won’t open when I type in the command to do so. To make matters worse, I triggered Denuvo’s anti-cheat protection and can’t open the game until 1:00am tonight. Can anybody help me?
Hedhehog Manager is probably the worst thing to get running on the Steam Deck. This guide worked for me last year, but stopped working around June for me (Steam updates only, no other changes). I’ve tried SteamTinkerLauncher, Protontricks/Winetricks, Lutris, Bottles. Currently it is borked.
I suggest manually installing mods if possible, which should work without issue. Though codes and other “hacks” that require different dlls loaded probably won’t work. You can use https://github.com/primetime00/memory_hack as a cheat engine to change values in memory though to get stuff like infinite rings in frontiers. If you play Sonic Origins, the music mods work via simply dragging and dropping the files, but for the other mods you will need to manually decompile the rsdkv5, drag the mod changes into it and recompile. This sounds complicated but much faster/easier/reliable than installing HHM on Steam Deck.
