I tried and it doesn't work. The error number is 5 and the description is "invalid procedure or function". I don't have any functions and my procedures all match up. I tested some downloaded games and some said that they couldn't be edited because they were made in a previous version of Quest. Some games got the same error I did. I tried my game on Quest and it worked, no probs I tested everything.

Should try opening up the .asl files and changing the version of quest it says they are using.

You should only receive a message saying you can't edit the game because it's a previous version if the game was designed for Quest 2.x.

Games for Quest 3.12 should still be able to be opened in QDK 3.5. However there is a bug in the current beta which causes a problem with opening some games. I'll release an updated beta this weekend which will fix this and a few other problems.
