c7f8f37822 Ensures typers terminate. 2017-12-30 13:46:30 -05:00
Thomas Harte
9339f3413f Liberalises the end-of-file test for MSX ASCII. 
From: must be back padded with 0x1a to merely must contain 0x1a.

6da8a3e24b Causes the MSX to respond to the appropriate standard configuration options. 2017-12-29 18:36:42 -05:00
Thomas Harte
e349161a53 Rejigs the typing relationship so that use of a typer is not strongly implied by the interface. 
Simultaneously implements typing on the MSX by direct insertion into the key buffer.
 2017-12-29 18:30:46 -05:00

d5b1a9d918 Moves the typer functionality behind a functionality-based naming scheme, eliminates its C-style memory management. 2017-12-29 15:26:03 -05:00

76af0228dd Corrects longstanding survival of camel case in the analyser's loadingCommand. 2017-12-29 15:15:29 -05:00
Thomas Harte
2cc1a2684a Introduces [over-]analysis of cassette contents prior to starting the MSX, and simplifies ROM checking. 
So a proper loading command is now known.

98a9d57c0b Imputes the alignment requirement for CAS headers. 
Also stops adding a spurious 0xff as the final byte on the tape.

c481293aca Liberalises CAS interpretation. 
It seems to be an even weirder file format than I thought; it can contain only ROM-formatted data but seemingly often contains blobs that the ROM cannot write.

5fd0a2b9ea Attempts to pull reimplementations of TAPION and TAPIN better into line with originals. 
Also improves whole flow of the fast tape hack that uses them.
 2017-12-28 22:48:04 -05:00
Thomas Harte
11b73a9c0b Adds preliminary, non-error-checking wiring in of MSX parser alternatives to TAPION and TAPIN. 
As both a prototype of the pending fast tape loading, and to provide for exact behaviour comparison.

c4950574ea Introduces an attempted reimplementation of the MSX BIOS's two main tape reading entry points. 2017-12-26 22:19:37 -05:00

9a7e974579 Corrects skipping of every other file, and transition from bytes back into header. 2017-12-23 19:20:04 -05:00
Thomas Harte
f4d414d6e4 Removes stray line break. 2017-12-23 18:42:04 -05:00
Thomas Harte
b4bfcd4279 Switches to an attempt to break the .CAS into files ahead of time. 
Hopefully the better to insert appropriate lengths of header and gap.

e8ddff0ee0 Makes a first, messy, attempt at serialising CAS files into audio. 2017-12-21 22:34:03 -05:00

f17758e7f9 Attempts better to deal with large numbers. 2017-12-20 21:03:24 -05:00
Thomas Harte
0bb24075b6 Immediate fixes: TSX is seemingly TZX 1.21; the tape motor control works the other way around. 
Input is not yet being recognised.
