Ophil: You could try searching the bug tracker at bugs.scummvm.org. If this is not a known bug, you probably should report it so it doesn't get lost.

scu_do_mundo: We can only really offer support for "vanilla" ScummVM since we don't really know what patches Retroarch may have added or changes they made. Best to talk to the Retroarch project about that. It _may_ be possible to use the Keymapper functionality in ScummVM, but again it wou...

nozomi: I think the ScummVM project leads will echo this, but it is nice to hear that ScummVM is being used in this way. To cover your bugs / issues, these should be reported on the bug tracker at bugs.scummvm.org with full details. You should do a quick search first to check that this is not a know...

Did you complete the medication correctly? My walkthrough says: "Sadie Ovaree will enter the pharmacy. Exit the pharmacy. West. West. Enter the saloon. Get the shot glass from Doc Gillespie's table. Combine the shot glass with Ovaree's prescription and then use the glass to read it. Give the sh...

I think there would be files called VIEW....

I Am Not A SCUMM Engine Expert... but I think keyboard fighting uses the Number Pad keys:
viewtopic.php?t=2165

The GOB engine has not had any development work recently, but the design of the original engine is problematic as the game scripts are quite buggy and can corrupt the game state variables in unpredictable ways. Coupled with buggy original scripts and corrupted / fan-patched script versions floating ...

If it is a bug in the Switch port release for v2.2.0, you should file a bug at bugs.scummvm.org and check to see if the bug is fixed in the latest development release ie.
