+The text printer in Emerald is very versatile and has a lot of control codes. But it seems Game Freak skipped implementing one of the control codes in the release of the game, since it was likely never used. There's a control code that pokeemerald calls the `SIZE` control code, allowing you to change fonts (and thus font size) mid-text. But there's another control code right after that called the `RESET_SIZE` control code that does nothing. Here's how to implement it:
+
+In the text.c, find the function `RenderText` and add the following:
+```diff
+            case EXT_CTRL_CODE_SIZE:
+                subStruct->glyphId = *textPrinter->printerTemplate.currentChar;
+                textPrinter->printerTemplate.currentChar++;
+                return 2;
+            case EXT_CTRL_CODE_RESET_SIZE:
++               subStruct->glyphId = textPrinter->printerTemplate.fontId;
+                return 2;
+```
+
+Further down the same file, find the function `GetStringWidth` and add the following as well:
+```diff
+            case EXT_CTRL_CODE_ENG:
+                isJapanese = 0;
+                break;
+            case EXT_CTRL_CODE_RESET_SIZE:
++               if (letterSpacing == -1)
++                   localLetterSpacing = GetFontAttribute(fontId, FONTATTR_LETTER_SPACING);
++               else
++                   localLetterSpacing = letterSpacing;
++               break;
+            case EXT_CTRL_CODE_PAUSE_UNTIL_PRESS:
+```
+
+Both of these will reset the font to whatever the previous font was when the text printer comes across a `RESET_SIZE` control code.
