First of all, thanks for helping me to debug this. You must understand from my point of view, all of my games use the same ways to play, so if the game won't load then it is difficult to discover the reasons. I see you noticed my RTG warning in the installer. I wont move or replace any system files on a users machine, as this is invasive installation and could damage other software. But at least the note in the installer is there to give you some clues. I spent all week trying to diagnose the issue, and that's the one thing I was sure was a culprit.
Good to know your setpatch seems ok. I tried 43.4 and it failed to load, so maybe a conflict with less than 43.6. CanDo itself wont run without setpatch, so I presumed it was the same for the games, but with KS3.2 it probably has those things patched internally, so no need for setpatch? I'm guessing in the dark here.
Anyway, for some reason I can't fathom, the HDD version of the game is still buggy (boy!), so I've uploaded the normaL EXE and icon as a downloadable file for you to test. It is the exact same game and version as V1.0A HDD, only without the HDD patch tools, and without the CanDo.library built in. As you already copied this library with the installer, there is now no need to use the big old executable anymore.
The normal V1.0A exe should at least fix the help not working. Sometimes if you gear up too quickly, it can take a second until the voice speaks the gear, before you can gear up again. As you start in 1st, and 2nd gear is perhaps 30 seconds further down the track, you should only be moving up to the suggested gear (in easy mode) when prompted.
Thanks for this, we are almost there!
