Here's my 15 or less percent finished game.  I havn't coded on this since this summer.  It's dead.
I wanted to make a RPG, but with many rooms.  I decided that storing each room needed to take as little room as possible.  The method I used was storing a number for each room to rand.  It worked, but rooms didn't mesh together at all. Because of the difficulty for finding rooms, I lost intrest.  I'm uploading a screenshot so you can see how it was going to look.  The code is riddled with placeholders for what was to come, so if you see the code that is why it looks wierd.  The best parts are the menus.

Here's my map maker for 8*16 homescreen tiles.

2nd-Pick tile
Alpha-Go to custom tile screen.  This uses whatever is in Str0 as its custom menu.
Clear-Clears Current Tile
Enter-Saves to Ans and Str1

Enjoy.  I'll have a gif up this afternoon.

Edit:  I "forgot" to mention the best part:
Press 1 to 5 to store the tile your cursor is on to F1-F5.  Enjoy!

Oasis is a basic shell that will run basic programs.  It uses Celtic III.

Let me know what you think.
