I tried to use mtool also with bob's translation, but after a while the tool stops because of the limit in the translation process and the game doesn't recognize some internal data and generates errors.Seems like you didn't waited enough after the launch of mtool before playing. You need to wait on the starting screen until the screen reset during 1s. After that you can load your save.
For the one patch I guess you can do the work with arzor translation one click patcher. I think my version doesn't have the one click patcher done because at this time this was just a way to play 3.4 until bob was done with his upgrade.
You can probably try to load mtool inside a bob translated version. I never done it before but it should work.
And I can't manually install the arzor patch on my side either, it usually gave me errors or corrupted the game itself. The only versions that worked for me were the ones you uploaded jsjsjs.
But no problem, the current version you attach doesn't stop me from continuing to play with Mtool, I'll just wait in case someone shares a version that links the tool with the one-patcher. Thanks for the recommendation anyway.
