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.
