Of sizes of data blocks previous to the required one, added to the position of the end of the table. slt, the emulator should find the correct entry in the table (type = 1, identifier matching theĪ register when the ED/FB instruction was encountered), get its size from the table and calculate its position from the total Supported if other values are encountered, that data block should be ignored by the emulator. Currently, only data types 0 (end of table) and 1 (level data) are z80 and attempted to load it into an older emulator)Īfter the "SLT" signature, there is a table of data types and sizes. With these three null bytes, they just complain about an error in the snapshotįile instead (this presumes you have renamed the. The three null bytes after the end of the snapshot are for compatibility reasons older versions of Z80 would crash if theĮxtra data was just appended to the snapshot. the following blocks are the data files themselves. the following blocks make up a table to access the data files -Ģ word data type (0 = end of table, 1 = level data)Ģ word data identifier (for type 1 this is level number) The format was designedģ bytes Three null bytes (compatibility see below) Rui Ribeiro (WSpecEm) and Darren Salt (helping with Z80Em), and is quite widely supported. It has been designed in co-operation with James McKay (x128), Gerton Lunter (Z80), The super level loader was developed by Damien Burke to replace this multi-file format with a single snapshot fileĬontaining all the level data files. The level loader trap has one annoying disadvantage lots of extra files lying around for each game. z80 format is now located on a different page. Into an emulator almost instantaneously, but cannot normally be used to recreate the original tape. Snapshot files represent the contents of the system memory at a particular moment in time. See the TZX Vault entry for a large number of files in. An extremelyĭetailed specification for the. Possible, in theory only since no utilities exist that allow it, save cassette images as. Only, it can also be used to reproduce tapes for the Amstrad CPC, Commodore 64, Enterprise, Jupiter ACE and SAM Coupe. Although originally designed for use with Spectrum compatible computers Non-standard loaders in a format much smaller than. tzx format was originally developed by Tomaz Kac (now maintained by Martijn van der Heide) to allow the storage of games with Tapes can be reproduced using a variety of utilities. TZX is the 'preferred' format for emulation since it can be used to replicate the original tapeĬontent exactly. tap files by simply stringing them together, for example COPY /B FILE1.TAP + FILE2.TAP ALL.TAP Then raw tape data follows, including the flag and checksum bytes. All blocks start with two bytes specifying how many bytes will follow (not counting the two length bytes).

tap files contain blocks of tape-saved data. Hardware type (for example) can often be encoded with files of this type, and custom loading systems are both reliably and accurately preserved. Additional information regarding the intended

They are generally preferred to 'snapshot' files, although they are slightly less well supported. Files stored in one of the following formats can be used to reproduce exact (or near-perfect) duplicates of the original source tape.
