Windows build will be up later plus more features (source already on GitHub):
- Left/Right and Centered text
- The program now automatically trims your text to length (26 characters) and allows only 4 lines.
- Adds those two extra FF values on the end that break the game if their changed (i.e. the hex is now fully independent, cut and paste into your ROM at 68D).
- Expanded the HEX data field to show all values with no word wrap.

Working on applying the fix directly to a ROM file or saving as an IPS, and adding support for any punctuation found in the game data.

So have they come up with a way to throw out the messages at whim like they did with Super Metroid like Subversion and Adcent where they got the room name on screen, or are you confined to editing the original "time bomb set!" End/intro text type stuff.
