(registered 2020-04-06, last updated 2020-04-06) Name: Connor Horman Email: chorman64&gmail.com Media type name: application Media subtype name: vnd.snesdev-page-table Required parameters: There are no required parameters. Optional parameters: There are no optional parameters. Encoding considerations: binary This format is usually binary data, however there is also a text based version of this format, which lacks the signature bytes (magic number), and is encoded as a csv table in the ISO 646 invariant subset of 7-bit ascii encoding. This version also uses this media type. Security considerations: The format can be used to describe the layout of virtualized memory within emulation software. Therefore it may be possible for a malicious file to exploit vulnerabilities within such software. The exact effects of this are not known. Additionally, the format provides no form of security or integrity protection (aside from a checksum, designed to protect against corruption, rather than malicious construction). As such, care should be taken when loading an untrusted file into such software. Interoperability considerations: There are no interoperability considerations Published specification: The latest published version of the specification can be found at https://chorman0773.github.io/BinarySpecifications/SNES-DevPageTable/latest. Applications which use this media: Emulation software for the 65816 processor can use this media type to generalize the layout of memory within the emulated environment. It can also be used by programming language compilers to describe targeted memory layout when generating code for the 65816 processor. It can further be used in conjunction with a physical 65816 processor through a memory mapping coprocessor, after writing the file to a persistent storage medium. Fragment identifier considerations: There are no Fragment Identifiers Restrictions on usage: There are no Restrictions on Usage Additional information: 1. Deprecated alias names for this type: None 2. Magic number(s): 00 70 74 FF (used by the binary form only) 3. File extension(s): .ptrom, .pt 4. Macintosh file type code: None 5. Object Identifiers: 1.3.6.1.4.1.54569.0.1.6 General Comments: No additional information Person to contact for further information: 1. Name: Connor Horman 2. Email: chorman64&gmail.com Intended usage: Limited Use The use of the format would be limited to 65816 emulators, code- generators, and memory mapping coprocessors which subscribe to the specification. It has limited to no use cases outside of these applications, Author/Change controller: Connor Horman
