| May 22, 2022 at 15:47 | comment | added | hippietrail | Now that I realize I'm asking about the Family Basic file format I found a thread where a couple of people have posted their disassemblies of that ROM: forums.nesdev.org/viewtopic.php?t=13237 | |
| May 22, 2022 at 15:40 | comment | added | hippietrail | @snips-n-snails: That's really cool! Listening to a couple of them it seems the BASIC files consist of a sync tone followed by a short header followed by the same sync tone followed by the program data, which can vary in length so the length should be one field of the header. I don't think I have the skills do analyse it further. | |

| May 22, 2022 at 15:13 | comment | added | Brian H | I'd assume tape images (used by an emulator) could at least be analyzed (in a hex editor) to understand the binary format. Though, I suppose the modulation details would require analyzing the actual tape audio, right? | |

| May 22, 2022 at 2:21 | comment | added | hippietrail | There is some incomplete low-level information on the Nes Dev wiki. | |
| May 22, 2022 at 1:55 | comment | added | hippietrail | The Nintaco emulator supports the tape drive and comes with full Java source code. It doesn't seem to include a document on the tape format though maybe there's an overview in the code comments I haven't found yet... | |
