I have updated the mod player extension to the second version. This release adds the ability to go back using B, stop and restart the mod using A/Y, and looks a bit better too. Get it here.
Also, I'm going to release the pre-alpha version of my text/ini file editor. So far, it has scrolling and cursor support, as well as saves back to the file, but nothing else. Please be cautioned as pressing start to save and go back WILL save your file in unix file format, not windows! Keys are arrow keys for the cursor, L+R for page up and down, select to change from insert to overwrite (does nothing now, because you can't insert or overwrite anything), and start to exit back to the main screen. Comments are appreciated. Get it here.
