If, you have RPG Maker Decrypter and know what you are doing, you maybe able to play to a certain point. ( I have not tested all routes all cg all battles all etc. ) You need : 鬼と刀のメリトクラシー Append. ( game + the append, you can get it from a lot of sites/torrents )
Make a backup copy of both of the above or save the zipped file, so you will not rage if you break something!
Lots of files/pictures/etc. are missing from the Steam version + Append + Uncensor.
When you download Sarica's file, unzip it and compare it to 鬼と刀のメリトクラシー Append unzipped, 鬼と刀のメリトクラシー Append is larger. You need to decrypt 鬼と刀のメリトクラシー Append, move the Graphics and Data folders or just rename them Graphics2 and Data2 or something else. You need to decrypt Sarica's File move or leave the Graphics and Data folder right where they are or move them next to Graphics2 and Data2. Graphics2 has files/pics/etc. that need to be moved into Graphics folder.( the decrypted one NOT the one in Meritocracy of the Oni & Blade ) You need to take your time and move/replace/copy over the files in Graphics ( again not into Meritocracy of the Oni & Blade ) with Graphics2. PLEASE take your time when you do this. Ignore Data2 folder for now. You could also do the reverse and Move Graphics2 into Graphics, BUT I know for a fact if you downloaded the right 鬼と刀のメリトクラシー Append the Graphics2 should not have any errors.
When you have replaced the file/pics/etc from Graphics2 into Graphics, move the files/pics/etc from Graphics into the Graphics folder from Sarica's game.(Meritocracy of the Oni & Blade or whatever you named it) Again PLEASE take your time, open the folder see what is missing in Sarica's Graphics folder and move the files/pics over. (you can overwrite the stuff that looks the same just to be 100% sure) When you have completed this go back and move Data into Sarica's game folder. Inside Sarica's game folder remove/move games (games.rgss) some place you can find it again. Fire up the game and see if it worked. If, the above did not work for you, move game (games.rgss) back into Sarica's game folder (Meritocracy of the Oni & Blade) so you can decrypt it again. If, you did the above correctly the game should work. ( again I have not had a chance to 100% test everything, but the game is no longer getting error's/crashing )
If, you can explain the above better than me please do, there is a lot of moving files around then back again.
I hope this works for some or all of you, until a PERFECT working game can be uploaded.
The method above has been used to fix the past games released on STEAM, while waiting for OneOne1 or Steam to release an Official fix/patch.
