These dumps cover the GBA version of A Link to the Past, which includes Four Swords. The ALttP text is encrypted in a strange manner, making it difficult to decrypt. The Four Swords text, on the other hand, is regular ASCII, making it easy to dump.
ALttP GBA Complete text transcript (v1.0). Not actually a text dump, but made by typing up every quote in the ROM. Contains every quote in the same order as in ROM, but there may be typos. Thanks goes to for making this transcript.
