23c34a8c14 Corrects calculation of intermediate buffer width multiplier. 
Specifically: I had failed to factor in that the multiplied-up input frequency might be less than than the full width of the bitmap.

The Atari and MSX in particular now look much better.

93ece2aec7 "Doubles" the bandwidth given to composite signals. 
Because I suspect it may inadvertently have been halved previously. I'm investigating.

0ccc104027 Corrects start sector and track interleaving for MSX DSK. 
MSX DSKs start with sector 1; Acorn disks still begin with sector 0. Also it turns out that MSX DSKs are indeed interleaved.

8be6cb827b Implements MSX interrupt/data request reading register. 
The disk ROM now appears to accept on-disk bytes, but still announces an IO failure.

Thomas Harte
999a0c22d4 Adds superficial support for MSX .DSK. 
In the sense that the file format itself is properly parsed, but the MSX doesn't actually yet have disk hardware.

Thomas Harte
655b971976 Establishes that there is such as a thing as a Konami SCC. 
Creates one, ensures it appears in memory when intended to, lets it handle reads and writes. It currently does nothing.

c07113ea95 Ensures no illegal accesses while testing MSX ROM type detection. 
Specifically: the static analyser doesn't even correctly identify everything that is an MSX ROM yet, let alone then properly determine type.
 2018-01-01 17:38:26 -05:00
Thomas Harte
bc2879c412 Corrects the MSX ROM unit test. 
I.e. the test is correct now, for those SHAs I could find. The static analyser is still wrong just slightly less than half the time.

bf0601123b Adds some document type UTIs. 
Will need to survey all the other Mac emulators to get a complete list, I guess.
