I managed to get myself stuck on a ladder and cannot get unstuck. I was exiting the Zora's Domain right after doing the Dive thing, was climbing the ladder as the timer ran out. Right as the timer ended, my character stopped and the avatar is frozen in a standing position (not climbing the ladder). I tried rebooting the program, but it just loads to the same glitched spot.
Can you post the save file? (It will be a very small file only a few KBs in size, located in PJ64's save folder, whose default location is either C:\Program Files\Project64 1.6\Save or C:\Program Files (x86)\Project64 1.6\Save.)
I can't give you verbatim instructions since I'm away from my Windows PC at the moment, but if you poke around in PJ64's settings, there is an entry that will let you see/change the path where PJ64 stores/looks for saves. Once you find that you should be able to locate the save file. If you're still unable to find it by Monday, I can assist you further if no one else has.
Sorry, I can't locate the file. Are newcomers unable to post attachments? (Should be available under Additional Options when posting a message. You'll have to either "Reply to Thread" or "Go Advanced"; it is not available in the Quick Reply box.)
In PJ64, go to Options->Settings... On the Options tab, ensure that "Hide Advanced Settings" is unchecked and click OK. Then go back to Options->Settings... On the Directories tab, there will be a section named "N64 Auto saves" that specifies the path to your save directory. Navigate to that directory and there should be a file named "THE LEGEND OF ZELDA.sra". Post that file here.
